883.1 | Kyosho So So | DISCVR::JONEILL | | Wed Feb 08 1989 14:53 | 7 |
| I too have a Kyosho Raider I got for my son. I've been real lazy
and still have a way to go. It's to bad they did'nt use a standard
bearing, it's hard to find the 4x8 they call for with out buying
the whole set ( I wasn't rich at the time and he had been patient
enough). I'll let you know my impressions as time allows.

883.2 | Over steer ??? | FSTRCK::HARGUS | | Wed Feb 08 1989 16:47 | 10 |
| .0
Could you tell me how bad the over steer problem was you had
and how much difference the new tires made. Alos have you considered
an eletronic speed controller for the car ?
Thanks Alot for this info, I am trying to decide wether or not to
buy the Raider myself. Price is right for my budget.

| How are ya Greg??Explain this oversteer and how rear tires corrected
this,I'm still dizzy trying to figure over/under/sideways/upsidedown
steer etc etc and how things correct them.I've been trying things
to death on my Blackfoot to correct steering problems to no avail.
I do believe my last stunt may have done(too much snow to really
tryit).I put 4 Proline Masher tires on(softer than original and
square on the edges as opposed to rolling off)seems to help the
flipping on corners.
As far as your servo's go,I bought a Futaba S-148 because I stripped
the top spline on the Kyosho with the giant servo-saver I put on
the blackfoot.I shaved off the key and it went right in,had to flip
the servo-reverse for that channel even though the polarity was
correct(black-,red+)This servo is far superior with a longer spline
for the servo-saver,Kyosho's is about 1/16"shorter and is just enough
to strip if you stress it.Other than this the 2000 is a pretty good
radio for the buck.

883.4 | Oversteer/understeer and tires on Raider | AIMHI::DWYER | Greg, MKO1-2/G38, 264-8070, ISM/FDG | Thu Feb 09 1989 13:40 | 49 |
| re. oversteer
Oversteer says your front end has good bite, but your rear end
breaks loose. Understeer is the opposite.
The oversteer problem on the Raider wasn't real severe as it came
out of the box, in my opinion (and on my home "turf", which is
fairly well-packed gravel). I have not started racing it on
a maintained track, so I'm still working with a limited amount
of experience. However, it's a guarantee that the surface you race
on will have a lot to do with handling, and that what works well
on one surface may work poorly on another.
What happened rather quickly though was that we wore out the rear
tires, which turned a little oversteer into a lot of oversteer.
The new pin spikes cleared it up nicely, and I feel they are
superior to the stock tires on at least my turf. Comments from
local racers tell me these tires are good at the indoor tracks
in our area (So. N.H.).
Dampening and spring rate changes can affect understeer/oversteer
conditions as well. If your suspension is too stiff, chances are
your tires will be bouncing and losing traction. Suspension too
soft, you'll have excessive roll or lean in corners and bottoming
over the rough stuff, causing loss of traction. And that loss of
traction will affect your steering control!
I think the Raider's suspension can be tuned up real nice with just
a little trial and error. I plan to have fun doing it! Plus
there'll be some tips on doing just that over the next few (?)
issues of the RC Car Action magazine, as their next "budget racer"
feature will be on the Raider.
Re. an electronic speed control...
When I buy my next one (soon I hope) I hope to do just that. But
on this one, when the stock rotary unit goes, I may try a wire-wound
from Parma. I understand they're a step-up from the stock 3-speed,
offering real proportional throttle. You can also get braking action
with these units, though I've a lot to learn on that aspect. Anyone
familiar with how this braking works? Do you still have a reverse
option on the wire-wounds with brakes?
I think I'm biased towards the Raider at this time. I looked at
a lot of cars before making the move. I couldn't find anything
close for the money.

883.5 | Info on Traxxas TRX-10 Bullet??? | AIMHI::DWYER | Greg, MKO1-2/G38, 264-8070, ISM/FDG | Tue Feb 14 1989 12:51 | 20 |
|
Here's a new tangent for the buggy's topic: The Traxxas TRX-10
Bullet.
Has anyone seen one of these in the flesh? Seen the kit or a
completely built and running machine? Read any test reports or
first-hand comments?
I've seen their advertising, and now I've seen Tower's price: $109
At first glance, it looks like a lot of car for the money.
I looked back through RC Car Action, but didn't see anything. I
could have easily missed it though, as I have to rely on their
"back-issue index" as I only have issues back to November or December.
Any info is appreciated, I'll post any further findings.
Greg (who's thinking maybe he won't get a second Raider!)

883.6 | A little info, would like more | PLATA::OSWALD | | Tue Feb 14 1989 16:09 | 16 |
| I was wondering the same thing. A local hobby shop (Colorado Springs)
has one for the $109.00 price and I looked at the box. The guy there
seemed to think it was very comparable to the RC10. It has oil filled
shocks, an aluminium chassis and oilite bushings. These were the
only things that seemed to me to really set it apart from the Raider.
I ordered my Dad a TRAXXAS Cat for Christmas. One of the things
that came in the box was a blurb sheet on the Bullet. Now that I've
decided I want a car too I can't find the darn thing, but one thing
I remember is that the motor in the Bullet is *NON* somebody legal.
I can't remember which orgainzation it was though.
Further info appreciated here also.
Raider order pending,
Randy

883.7 | Traxxas TRX-10 Bullet | AIMHI::DWYER | Greg, MKO1-2/G38, 264-8070, ISM/FDG | Thu Feb 16 1989 12:39 | 39 |
| Well, I yielded to temptation yesterday: I bought a Traxxas TRX-10
Bullet kit. I went through the kit and instructions last night.
This will be a fun project, there's certainly more challenge in
it than there was in the Raider.
Before purchase, I checked out a completed chassis. Felt good
and stiff/solid, good suspension travel, little if any slop
in any joints, but also a heavy buggy if you use the stock
speed control (it's got a three-pack of 5 watt ceramics in a
big heat sink). I don't think it offers reverse, either, but
I need to go back over the specs/instructions a few times before
it will all sink in.
Comes with bronze "oilite" (whatever that means) bushings.
At this time I'll venture a guess: This may be a little more
for your money than the Raider. However, consider Kyosho's
momentum in this business. Plenty of parts, both from Kyosho
and 3rd parties, and good basic designs that can be easily customized
and maintained.
How will Traxxas fair in the long run???? Hope my little gamble
pays off.
At least the shop I bought it from had a full complement of spares
for it. It also appears that bearings, connectors, linkages, and
wheels are "industry standard" (i.e. Tamiya, Kyosho, etc. clones).
If anyone's interested, I'll update this topic as the kit takes
shape.
Geez, now I gotta get a radio, batteries, and I should get another
charger ($$$$$$$$$).
Can I afford this hobby? Hell no, but what a way to go broke!

| Re. .9
Eric, my Bullet chassis is together and waiting for a radio.
I'm not sure I'd call it a tank, but it seems solid enough in most
aspects. It might be nice to have a wider front bumper, the
stock unit does not extend to anywhere near full wheel-track.
The body may/may not prove durable: the design of the tail end
makes me think it will be prone to *excessive* flexing during
tangles on the track, and may not hold up.
I'm very impressed with the chassis/suspension/steering gear.
I wish it had a R.O.A.R. legal motor.
I wish I had a radio so I could start track testing it. >:v(
I'm still convinced (at this early stage) that it's a lot of
car for the $$$$.
Gimme a call if you want to hear more,
Greg

883.11 | I like mine too | PLATA::OSWALD | | Wed Mar 01 1989 12:06 | 15 |
| I too broke down and bought the Bullet. Its sitting on the shelf
waiting for the radio from Tower to arrive so I can finish it.
I second the opinion that it seems to be a lot of car for the money.
It went together well and looks sharp. My only complaint is that
all the plastic parts (most all of the suspension and the front
bumper) are molded not in black, but in wimp white! The box and
the instructions show it in the normal black which looks much better.
Oh well, for $109.00 I'll live with it.
Does anybody know why the motor isn't ROAR legal?

I can hardly wait to here how it performs on the track. Can either
of you (or others)compare it to the RC-10 or Ultima Turbo ???
What motor will you put into the car after the first one burns

except that the motor it comes with will burn out very fast..
they did not say why ..)
Thanx for the info....

883.13 | Good car | RVAX::SMITH | | Wed Mar 01 1989 15:34 | 15 |
| My son has the bullet also. For the money, it is a very well built
car. Set up correctly, with the right motor etc., it compares very
favorably to my RC10. Several people I race with have them and in
the hands of an experienced driver, there definately competitive.
As to the "plastic", actually I believe it is nylon, it's the dyable
nylon which enables you to dye the parts any color you want. That's
a nice advantage for someone that's detail oriented rather than
sticking you with one color.
I suspect the motor (which is junk) is part of the reason the car
is priced the way it is.

883.14 | More Bullet ramblings... | AIMHI::DWYER | Greg, MKO1-2/G38, 264-8070, ISM/FDG | Wed Mar 01 1989 17:16 | 26 |
| re. the limp white color
I dyed several components on the Bullet to black (roll cage, bumper,
knock-off hubs). I may someday do them all. It's an easy and
effective procedure that not only helps in the esthetics department,
but supposedly "stress-relieves" the nylon (or delrin?) parts.
re. compared to RC10
In many respects I think it's a clone of the RC10: suspension
design, modularity of construction, component layout. The
chassis is not a tub though, as is the RC10, it's an almost
perfectly flat aluminum pan with a fiber radio plate/stiffener
mounted about an inch above.
re. the motor
A dud huh? Oh well, it should last me through "driver ed".
My son and I are trying to decide what motors to pick up
come serious racing time. We'll be stock class, can't afford
anything else. Trinity seems to have a good rep as a motor
vendor, but then there's Reedy, Twister, etc. etc.
Suggestions on motors would be much appreciated!

883.15 | Motor Info | RVAX::SMITH | | Thu Mar 02 1989 10:18 | 15 |
| Most clubs have a specific list of motors they will allow to run
in the stock/superstock class. Most major brands are covered, but
then again, some are better than others. I, as well as most of the
people racing in superstock are using the SPEEDWORKS DIRT/OVAL stock
motor. At least those of us that are winning. This motor sells for
$28.00 which is the usual price limit for stock motors. The speedworks
motor is made by Trinity. One of the other guys tried the Reedy
superstock motor, and went back to the speedworks. Twister is supposed
to make a good/fast stock motor but I don't know of anyone using one
at this time. If you do pick up the speedworks motor, make sure
it is the BLUE LABEL. They make other "stock" motors with different
color labels that are not legal for superstock.

883.16 | trash it if it's hot... | NINE::COMINS | | Thu Mar 02 1989 11:10 | 8 |
| Just a word of advice...
When you notice the 'junk' motor starting to get unusually hot after
a run, GET RID OF IT! It will only get hotter with each run and
eventully start melting any plastic near it. Once you buy a decent
motor for it you'll wish you had it since day one.

883.17 | Motors and heatsinks... | AIMHI::DWYER | Greg, MKO1-2/G38, 264-8070, ISM/FDG | Thu Mar 02 1989 12:58 | 17 |
| re. thoughts on motors
Thanks for the tips. I am looking at adding a heatsink on both
cars (my Bullet and my son's Raider). I know that it won't help
much in offsetting the Bullet's stock motor if (when) it exhibits
the overheat problem, but it may help the future motors. Now
finding the best heat sink for both these cars should be interesting!
The Bullet being relatively new, and the Raider (also relatively
new and unproven in terms of popularity for aftermarket parts
houses) with its mid-engine design, will both pose problems in
finding the right heatsink.
Well, time will tell (gotta get that radio first).
Thanks again for sharing the info,
Greg

| ****Update on Traxxas Bullet****
Remember way back in February I replied saying I picked up a Traxxas
Bullet? Of course you don't, you've all got better things to remember!
It does seem like quite a while to me, because I'm the one who's
been staring at the completed chassis/body and wishing I had the
radio.
Well now I've got the radio!!!!!
Picked up a JR beat 2 Alpina, and I'm hoping this will be a good
choice. Had a problem right away with the transmitter though,
wouldn't transmit! Swapped it the next day, no problems, down
at Hobby Etc. in Nashua. This seems like a very good radio, and
I'll try and report further after I have some hours on it.
Now to the Bullet: It's got problems. First and foremost, those
folks who responded here saying the motor is junk seem to have hit
the nail on the head. After ~3 minutes run time it was too damn
hot. It began to draw some serious current, too (no surprise, huh).
Secondly, I'm not at all pleased with the speed control. Sure,
when I first saw it I knew it was too heavy and too bulky to be
considered for a competitive racer, but I figured it would at least
suffice during my learning curve with the Bullet. Not so, at least
at this point. The contacts on this controller are flakey. I cleaned
and tweaked the pressure/angle to no avail. There are just too
many "dead" spots in the arc (this is a 3 forward + reverse rotary
type). Also, I'm concerned with the values of the resistors used.
There are three resistors: first speed has the power routed through
two of them (a .15 ohm and a .22 ohm), second speed routes power
across the .22 ohm ownly, and third is straight through. Reverse
drops voltage across all three. Know what? There's not enough
power left in reverse to move the weight of the Bullet on a slightly
rough surface! First is barely useable too. It's not until you
hit second that the car gets any reasonable motivation at all.
In third it moved along nicely, but as I stated earlier, the motor
heated up quickly so my fun didn't last.
I will say that in my brief shakedown, that chassis/suspension/
steering combo does seem to perform (even with all that excess
fat!). The car cornered well, jumped beautifully, and showed
real promise. I will be making some small adjustments, like
removing the sway bars (they're great for flat tracks, but I'm
not convinced they belong off-road), adding some shims/spacers
here and there to correct clearance problems, and swapping the
stock front ribbed tires for some spikes.
I'll also be talking to both Traxxas and the dealer today, as it just
ain't right to sell such low quality components as that motor (and
maybe that speed control too, although resistor changes may help
there).
Any of you other Bullet owners still out there? How's it going?
I'll update the note as the story unfolds!
Greg
P.S. I'll have my own off road track ready in a few weeks. The
10-wheeler load of screened loam arrived this weekend!

883.20 | Tie rods on Raider | AIMHI::DWYER | Greg, MKO1-2/G38, 264-8070, ISM/FDG | Wed Apr 19 1989 11:16 | 25 |
| re. .18
Not only do they not line up, you'll also find that they rub on the
chassis at both extremes of suspension travel. I "adjusted" (i.e.
bent) the ones on my son's Raider, then modified the chassis to
stop the rubbing. The chassis mod was nothing more than some
careful filing in the right places. You may have to remove quite
a bit of material though on the upper rear corners of the steering
linkage cutouts in the chassis. The best advice I can give is go
at it slowly, remove a little at a time, and check to see how much
ground you've gained. On the encouraging side, my son has many
hard hours on his Raider, and the chassis (as well as the rest of
the car) is holding up well.
Have fun,
Greg
P.S. Try to minimize the number of times you pop the rod ends on
and off of the ball joints. These are a high-wear item, and you
don't want to accelerate the process. My son and I plan to replace
all the stock rods/ends with better quality (on-the-car adjustable)
hardware. It doesn't cost much and makes maintenance so much easier.
And there is plenty of maintenance on an off-road machine!

883.21 | so fd | ORIENT::JONEILL | | Wed Jul 12 1989 08:50 | 14 |
| I must just be spoiled. I just finished my sons raider and
I guess I expected more. I know, it's only an entry level car
but it did receive alot of praise in the right ups. It's not much
faster than a grasshopper with a 540 from what I remember ( he had one
of those also) and I'm not impressed at all with Kyosho's cars.
I myself have an RC 10 and thats why I think I'm spoiled, mind you,I
never expected the raider to perform like an rc10 I just thought it
might be a little quicker. As far as the tie rods hitting the frame,
I only notice it when your holding the car off the front wheels so
I did'nt have to file or cut anything. I will say it handles alot
better on road than a grasshopper with a 540, I'm not to fond of
off road , to much time spent cleaning up after a run. My feelings
may change after this weekend when we can take out to a good size
area and I'll let you know how it goes.

883.22 | Faster Raider... | AIMHI::DWYER | Greg, MKO1-2/G38, 264-8070, ISM/FDG | Wed Jul 12 1989 18:32 | 25 |
| re. .21
Did you use the optional gearing? In the kit they supply two idler
or counter gears (I can't remember correct term). Try the optional
one. Your final drive ratio will see a nice percentage change in the
"go-faster" direction.
We just did this to my son's Raider, as he feels he's ready for more
speed. The car is noticeably quicker/faster! He's blowing my
doors in (Traxxas Bullet) and loving it. Dad will catch up though,
as my only major problem (speed-wise) with the Bullet is the low
quality stock motor. Okay, it is a little on the heavy side too,
but we'll take a big chunk out of that when I dump that mechanical
speed controller!
BTW...For all you folks looking at 2wd off-road machines, the Bullet
should be a definite consideration. The chassis/suspension is GOOD,
and the price is right. Also, Traxxas is introducing new goodies
for it (lightweight components) and aftermarket outfits are beginning
to do the same. Add to this the tremendous support that Traxxas
seems to offer their customers, and it's even more appealing (my
calls to their 800 # have been VERY rewarding. I'm sold on dealing
with these folks!).

| re. .24
Jim, I think a Raider would fill the bill nicely in terms of
cost and durability. They can also be easily modified if racing
becomes important. I'm currently maintaining or helping to maintain
the following: 2 Raiders, 1 Futaba FX-10, 1 Minicraft Lazer, and
my Traxxas Bullet. There's no end to maintenance on dirt-track
machines in general, but of all the above, the Raiders are holding
up the best. A key point: *my* 12 year old (he'll be 13 end of August)
needs plenty of assistance in the maintenance department. If I don't
work with him continuously, he'd have a lot more down-time and much
bigger maintenance $$$$$. He's learning, but I think that age group
will need lots of Dad's (or someone's) help unless they're
independently wealthy.
Don't rule out the Futaba FX-10, it's a good buy! You can pick them up
for around $50, where a Raider is more like $80. Avoid the Minicraft
Lazer!!!!! Not worth more than, say, $30 compared to the other two
(Raider, FX-10).
Oooops....gotta run to a training session. More info needed?
Let me know!

883.26 | This and that... | AIMHI::DWYER | Greg, MKO1-2/G38, 264-8070, ISM/FDG | Tue Aug 08 1989 13:36 | 33 |
| Geez, things are so quiet in the "off-road" topic...guess I'll
throw in a thought or two.
Just built another Lazer for a friend's son. This one had the same
major problem as the first one I did: sloppy differential/gearbox.
Without adding shims (not in the kit, not mentioned in the instructions)
to keep the spiders firmly (but not too firmly) located between
the side gears, these units almost immediately self destruct. It's
a shame to have kits like this out there. Especially so since they're
promoted as "perfect for beginners"!
My Bullet is laid up waiting for Traxxas to send a new gearbox. I
hit the a-arm mounting area with motor cleaning spray (overspray,
my fault!) and yes, the stuff will make certain plastics brittle!
The next morning I found the Bullet listing to one side as it sat
on the shelf! No impact was needed after that spray made contact!!!
Traxxas is using a new material for the boxes now, and mine is on
the way. I'm taking this opportunity to install bearings as well.
Hope it makes a noticeable improvement!
My son's Raider is in dire need of a new speed control. Seven + months
on the stock rotary has done it in. I've patched it up a few times,
but feel enough's enough. We (he?) can't afford electronics yet, so
I'm shopping for a wire-wound. Anyone out there have experiences with
wire-wound speed controllers to relate? Remember, the Raider is stock
off-road, still running the LeMans Stock 05 motor from Kyosho, 7.2v
power source. Inputs would be appreciated!
Enough for now. Hope everyone is having a fun summer.

883.27 | New car time... | FROSTY::DWYER | Greg, NaCM, MKO2, 264-8070 | Wed Nov 07 1990 14:34 | 43 |
| Well, at the rate of about one reply every six months or so, this
topic will never be accused of eating up too much of anyone's time!
>;v)
I've got questions for anyone that's had experience racing and
maintaining the following: RC10, JRX2, Kyosho ULTIMA.
The questions:
How often have they broken, and what part/parts have been most
troublesome?
Can you give any examples of how much replacement parts have
cost (e.g. had to replace the gearbox, new one cost $20)?
What stock parts were not up to par and had to be replaced to
make the car competitive?
Why I ask? My son's ready to "move-up" from his Raider, so I'm
going to get him a nice Christmas present. Prices on all of the
cars above have gotten quite attractive over the last year. For
what you get, I don't know if I could find better at this time.
However, if you have any other new car suggestions (1/10 scale
gearbox class) I'd love to hear them.
Any ideas and answers are appreciated!
Greg
P.S. FWIW, I'm still running the Traxxas Bullet mentioned several times
in this topic. It's gone through plenty of change though.
It is now fairly lightweight, has a Tekin ESC, has gone back
and fourth from off-road to on-road (radically lowered, stocker
bodied) and is now torn down for a gearbox overhaul (it's
going to spin smoother and easier than ever when I'm done).
I ran a Trinity Speedworks Joel Johnson stock motor for the
last season. It was fast, but not torquey enough for the
tracks we run on. I'll be replacing it soon to get competitive
for the winter on-road season. One last note, the JR Beat
2 Alpina radio system has been super! Liked mine so much that
I got one for my son last Christmas (Along with a Kyosho ESC500
electronic speed control).

883.28 | JR-X2 reliability | CIRCUS::MBROWN | | Tue Nov 13 1990 19:30 | 24 |
| I can comment on the reliability of the JR-X2, which I have been racing
off-road for about two years. The most vulnerable parts of my JR-X2
have been the spindle blocks (those plastic parts into which you press
the front axles and king pins) and the rear axles. I have broken two
spindle blocks and bent three axles. Losi is always improving the
weak parts; each time I have bought a new set of spindle blocks or
a new rear axle, I've noticed some little change, and each part does
seem to last longer. RPM now makes Losi spindle blocks and guarantees
them unbreakable; I haven't seen any aftermarket rear axles.
Losi spindle blocks cost about $5 per set (includes right and left
spindle blocks and spindle carriers), and rear axles are $6 each
(includes a drive pin for the rear wheel.) So the cost of these parts
is down in the noise compared to normal wear items like rear tires,
motor brushes and spray, etc.
The JR-X2 has been superceded by the JRX-Pro, which includes all of
the parts needed to make the car competitive on most tracks -- long
chassis, H-arm rear end, etc. On some tracks the short chassis and
5-link rear end of the original JR-X2 will be better. Both Losi cars
have the same transmission, which is a good one that doesn't need
replacing (unlike the RC-10 and Ultima.) It sounds like you plan to
run the car on-road, and I am not knowledgeable about that. I guess
you would need new tires, at least.

| I'll add my vote for the JRX-2. If you are planning to run primarily on-road,
I would NOT get a JRX-PRO. The 5-link rear suspension will be superior to the
H-arms on carpet or asphalt.
All the cars you mention are good competition-level kits. I believe the JRX-2
is the most competitive "out-of-the box". Both the RC10 and the Ultima are
competitive at our local track but most have be "customized" with various
after-market parts. The new "Stealth" transmission from Associated has
dramatically improved the RC10 competitiveness.

883.30 | JRX-PRO | FROSTY::DWYER | Greg, NaCM, MKO2, 264-8070 | Tue Nov 19 1991 20:06 | 13 |
| Hi, this is Justin Dwyer, Greg's son. I have had my JRX-PRO for roughly a
year, it is the best car I have ever driven. I have only one problem after a
few races the cartridges in my shocks start to leak like sieves, it is costing
me big bucks to keep up with leaky cartridges. I was wondering if any body has
any suggestions in this field, my Dad said "keep them cleaner" but I think
theres more to it than that? But other wise I'am pleased to be an owner of a
PRO.Its not a beginers car but it would be goood for some one with a year or
so of experience. I just finished converting my car to On-Road. I plan to
race at Hobbys Etc in Nashua. He has a carpeted banked oval (Perfect for fast
lap) I hope to add to my trophies which I won at Hobbys Plus with my Raider it
moved out pretty good for a beginners car. Thats all for now.

883.31 | Couple of questions | SNAX::SMITH | I FEEL THE NEED | Wed Nov 20 1991 08:21 | 13 |
| Where are the shocks leaking from. The top where the cap screws on, or out the
bottom?????
If it's the bottom, take the shocks appart and make sure the TWO tiny "O" rings
are there. Make sure the opening that the strut goes through isn't worn.
If it's leaking out of the top, did you remember to put the plastic semi clear
flat washers on the top of the shock before screwing on the cap??????? If you
did, you can go to the local hardware store and get a couple of rubber "O" rings
to put under the cap and seal it up.

883.32 | LOSI Shocks use a cartridge | CGHUB::DWYER | Greg, NaCM, MKO2, 264-8070 | Thu Nov 21 1991 20:44 | 12 |
| Re. .31
Hi, Steve thanks for the info, but my shocks cartridges screw up from
the bottom. There is a cartridge that screws up into the bottem of the
shock. I notice that it seems to be leaking from where the shaft comes
out of the cartridge. I noticed when I looked in side the cartridge
there were rubber "O" rings. I have a feeling that the ovaling out
of the cartridge opening and worn "O" rings could be the problem.
I wish I could think of a way to stretch their life, but it seems
that it is imposible.

883.33 | new Losi cartridges on the way | CIRCUS::MBROWN | | Mon Nov 25 1991 13:05 | 17 |
| You are right, Losi shock cartridges leak. Even a new one often leaks.
Rumor has it that Losi will soon be selling a "non-compensating"
cartridge that won't leak. Non-compensating means that oil won't move
down into the cartridge as the shock compresses (cut a Losi cartridge
apart if you don't know what I'm talking about.)
With the new cartridges, Losi shocks will be "emulsion" shocks, just
like Associated shocks are. Emulsion means that you leave air in the shock,
mix the air with the oil (to form an emulsion) by compressing the shock
once or twice, and the air compresses as you compress the shock. It
takes some practice to leave just the right amount of air in the shock.
You need to run a slightly thicker oil because of the air mixed in.
If you want to solve your problem *now*, buy a set of MIP cartridges
for your Losi shocks. They work like a charm.
