Airtronics and Futaba use completely different connectors. They
are _definitely_ not compatible. I like the Airtronics connectors
better because they don't leave those three pins sticking out
waiting to get bent. The male connector has a sleeve that protects
the pins.

Forgot to mention that I'm not sure about compatibility between
the Airtronics and Futaba transmitter charging jacks (last memo
was about the airplane side). I think the jacks are the same but
not sure about polarity. Simple thing to check. I assume this is
an issue because you don't want to use the factory charger that comes
with the system?

| Airtronics and Futaba Charging Jacks are similar but NOT compatible.
Servo connectors are not compatible either. The best thing to do
is stick with one brand if you already have some equipment so that
you can mix and match servos, chargers, and cyclers. I wish I had
followed this advice and saved the trouble of making adapters for
my cycler and charger.

| 920.7 | Try Dean's for compatibility | PEE47::COX | So Speedy, how do we get zeez brains? | Tue Mar 07 1989 15:30 | 23 |
| Many of the more experienced members of our club convert their systems
over to Dean's connectors, shich are available from ACR R/C and most
large mail order places and local hobby shops. Here's how:
Buy a handful of Servo pigtails that match your Rx, lets say Futaba.
Solder a Dean's three pin connector to the other side.
Solder Dean's connectors to all your servos. The beauty of this is its
easy to take advantage of different servos in your collection and also
the great buys of Royal and ACE servos which can be had with leads only
or Dean's connectors installed.
Use Dean's charging jacks and put Dean's connectors on your battery,
charger, ESV, etc.
You may ask why convert to Dean's and not all Futaba, JR, AirTronics,
etc.? Simple, Dean's is inexpensive, easy to find, allows you to build
your own harnesses -AND- they are easy to use!

Can't tell you how many times I've been tricked into thinking that the
heat shrink tubing that comes with the deans connectors actually fits.
Slide the heat shrink on the wires, solder the wires, try to slide the
heat shrink back, curse, cut all the wires, slide larger radio shack
heat shrink on the wires, solder the wires, slide the heat shrink back.
Real easy:=)

| 920.13 | I say No to the Dean's Fix | LEDS::WATT | | Thu Mar 09 1989 11:42 | 13 |
| I think that converting to Dean's connectors is costly and risky.
Cost wise, a pigtail for futaba is about $5 where a whole servo
is only about $15 on sale. Adding another connector to each servo
pigtail reduces reliability. Connectors can separate and the place
where vibration causes broken wires is at the solder joint on
connectors. The solder wicks up the wire strands and stress develops
right where the solder ends. I recommend avoiding modifying or
soldering any flight pack connections. THe manufacturer has tried
to minimize this problem and an inexperienced customer can really
screw things up with bad solder connections.

| As was mentioned here before, Futaba's new stuff is NOT connector
compatible with the older AM stuff like the Conquest. Therefor,
you can stay with Futaba and still have a round peg and square hole.

| 920.16 | Deans connector wiring standard? | COOKIE::R_TAYLOR | Richard Taylor | Fri Jan 24 1992 01:05 | 26 |
| Well, a good idea or not, I have decided to go the Deans connector
route for my batteries. The idea is to get Sanyo Rx packs ($9.00 from
Tower), Radio Shack DPDT switches ($1.50) and Deans connectors for the
charging jack ($6.50 for 6 from Tower). I intend to solder the battery
to the switch directly and then put on two connectors, one a Deans for
charging and the other a manufacturers for plugging into the Rx. The
total cost is about $14 compared to $25 to $30 for the manufacturers
battery and switch.
My only question is whether there is a standard way of wiring up Deans
connectors? I have the 3 pin connectors as they are on special now and
you effectively need three pins for proper polarization. How do people
wire these up for servo connectors?
If the connector is:
pin, gap, pin, pin
I would have thought that the best thing would be to have ground in the
middle and wire up a servo connector as:
power, gap, ground, signal
and that the power connection would be the same without the signal. Or
maybe I should ground the signal as well. How does anyone else do it?

| 920.17 | Here's how I do it | OLCROW::PHILLIPS | DECtp Engineering TAY1-2 DTN 227-4314 | Fri Jan 24 1992 09:05 | 24 |
| I use the Deans 3 pin connectors on all my battery packs. I swap one male and
female pins on each connector like so:
----------------------------
| | |
------------> | signal | power gnd |
| | female | male male |
| ----------------------------
| || || <------ male pins
connector blocks |
| |
| || <---------------------------
| ----------------------------
| | male | female female|
------------> | signal | power gnd |
| | |
----------------------------
I think I picked this one tip up from the ol' Desert Rat hisself! I believe
this wiring setup(signal, power, gnd) is the way Futaba and JR packs and serovs
use.

| Yes, though I've since standardized on Airtronics, my deans connectors
are wired with signal,gap,power ground. This is the pattern
recommended by ACE when I put my radio together.

| 920.19 | JR 321 servo wiring ? | KBOMFG::KNOERLE | | Mon Jan 27 1992 09:30 | 6 |
| I need to convert my JR 321 servos to our Multiplex connectors. There
is an orange, red and brown cable. Could someone please tell me what is
what ? (Signal, +, GRND)

| Well I did it. Next time I will change the following:
1. I used an open Radio Shack DTDP slide switch, (2 for 89 cents), and
wrapped the switch in duct tape to keep out dirt etc. Next time I will
use a better switch that is already sealed.
2. After wiring up the switch with ground on one side and power on the
other, I looked inside a spare Futaba switch. They use a DPDT switch
but common the ground and connect the power to both poles of the
switch. The ACE catalog also suggests that you wire up their switch in
this way. I suppose that it is in case one pole fails, you still have
the other. Next time I will follow the industry standard.
