| 570.1 | Algebra Sailplanes | USRCV1::BLUMJ | | Fri Jul 01 1988 09:39 | 19 |
| I JUST RECEIVED MY 4-METER ALGEBRA SAILPLANE FROM EDMONDS HOBBY
IN England. I was very impressed, the kit came in two weeks, shipped
in a great box. There was absolutely no damage and it was delivered
right to my door. The total price of this kit including all shipping
was $158 U.S. dollars. Wilshire Hobby out of California offered
this kit in the 2.5-meter version earlier this year for $170 + shipping
however, they no longer offer the Algebra line. I became interested
in this ship after reading an excellent review of the 3-meter Algebra
reviewed in Radio Control Soaring Digest. The Algebra line is offered
in the following wingspans: 2,2.5,3,&4-meter. All are available
with either the Eppler 393 or Selig 3021 airfoil, obechi sheeted
foam wings, glass fuselage, and can be built straight wing with
ailerons or bent wing for rudder,elevator,and spoilers. If anyone
would like to order one of this ships or would like literature call
me at DTN:252-7024. Oh by the way spare wings and fuselages can
be purchased separately(what a great idea).

| 570.4 | Algebra Building Update | USRCV1::BLUMJ | | Wed Sep 07 1988 14:46 | 17 |
| I am just about ready to install the ballast tubes and spoilers
in the foam core wings. Up to this point the building has gone
pretty well, but this is where it gets interesting. This is a
tough ship to pur spoilers in due to the thin airfoil and fuselage,
as well as the rearward mounting positiion of the wings to the
fuselage. I will be using barn door spoilers actuated by a string
to a common servo, as this is the only arrangement that will appear
to work without a great deal of fuss each time the ship is rigged
to fly. It appears my wing rods were installed O.K. as the fit
and symmetry of one wing to the other is good. This was a critical
and tricky job! At this point I am still satisfied and glad I bought
the kit, it certainly is different looking in a good way! I hope
to have it flying this fall.
Regards,
Jim

| 570.5 | Is it Flying... | TRUCKS::HORNBY | Soaring..not just for the birds | Fri Feb 03 1989 12:49 | 6 |
| I've just discovered by reading this note that it is the real ERIC
H. (I thought there could only be one of them)...
Regarding the Algebra.... is it finished, howsit fly?

| 570.6 | Marriage and Models don't Mix! | USRCV1::BLUMJ | | Wed Mar 15 1989 08:58 | 8 |
| The nemesis of all model aviation has stricken my Algebra - I got
married! I recently bought a house which required attention, so
that has taken up my time. I hope to be back on the project soon.
It is my goal to have it flying this summer.

| 570.7 | Algebra building progress | USRCV1::BLUMJ | | Mon Apr 24 1989 17:45 | 8 |
| Against the advice of the designer, I have elected not to put the
ballast tubes in the wings. I will however cover the inner panels
with Dan Parson's .6oz glass to improve the wing strength. The
installation of spoilers really seems to have been an afterthought
on this ship. I really didn't see a good way to do it when the
ballast tubes were installed. Since I am not planning on winch
launching this ship, I hope things will work out. By the way I
opted for barn door spoilers.

| 570.8 | Algebra 4-meter review | USRCV1::BLUMJ | | Fri May 04 1990 15:03 | 24 |
| A long time ago I talked about the 4-meter Algebra kit I was
constructing. I promised a review, which I will now deliver.
The kit is kind of hard to build because the fuselage is hardly
wider than a standard size servo. Fitting the three servos and other
radio gear was tedious and sometimes frustrating. Overall it is
a very good kit which provided exceptional value($141). How did
it fly? Great in a word. I was concerned that it would be difficult
to launch on high start. It wasn't, it climbed and tracked beautifully
on Magnum High Start's lightest rubber. Other large polyhedral
Sailplanes I have flown were sluggish in response to rudder commands,
the Algebra was incredibly responsive. The Selig 3021 is great on this
ship. It is deceptively fast, because of the 151" wingspan it appears
to fly slowly. This ship can be trimmed back for slow flight with no
nasty tip stalls or any other bad habits, but it really covers a lot
of ground when you want it to. It is really easy to land because it
flies very well at slow speeds. The stall is gentle with no, I repeat
no tip stall tendency. It is very beautiful and majestic in flight
with its 21:1 aspect ratio. This is a delicate ship which will not
tolerate hard landings, cartwheeling, or zoom launches. It truly is
a great flying glider.
Regards,
Jim
