  I have a one third scale R/C Biplane that I have decided to
part with. This is a Bud Nosen model of a 1933 Gere sport
Biplane. It has a 96 inch wingspan, and a 28cc Mac engine.

 This is a mostly competed model.. the wings and tail surface's
are built and ready to cover. The fuselage is about 95% complete,
the motor mounts and landing gear are all in place. The fuelage
has been sheeted and shouldn't be much more to finish it.

 I have lost interest in this project due to the SIZE of this
airplane. It would make a good model for someone who is into
large scale planes.  I'd like to get $250.00 for it,but will
take offers.

Subject: US Aircore Trainer, Any Good?
Organization: Rome Laboratory, Network Design Facility
Date: Tue, 25 Aug 1992 19:18:50 GMT

I am about to get back into modeling after about a 15 year hiatus. I used
to build and fly C/L and have built a Golberg Eaglet 25 with a 3 channel
Futaba (it crashed and the the radio was stolen during a move) in the past
and was wondering what the net thought of the Aircore Trainer I have seen
advertised.  I saw the video of it crashing (apparently undamaged) that the
company sends out and was impressed.

So, bottom line.......

Is the US AirCore Trainer a good plane to begin RC with
(I will be getting an instructor to help me this time around :-)  )

What engine would be recommended for this?

Any strong suggestions about a decent beginer/intermediate radio setup?

Thanks in advance for the help!

Kevin -

Definitely redo it. If your control surfaces are too stiff, you'll strain
your servo, resulting in a shortened life of the servo, increase current
draw for the servo which will drain your flight pack battery, increasing
liklihood of a crash. Redo the part. Control surfaces should all move
freely. Tight or binding ailerons, elevators, rudder can also fail to 
return to center properly, resulting in some interesting aerial effects
and a very exciting and short flight for you.
 
By the time you get done with it, you are going to have a couple of
hundred bucks in your airplane. You owe it to yourself to minimize
the problems.

Well, the R/C airplane(singular) could land on the large model carrier.  Now,
I didn't say the carrier would be the same scale as the airplane.  That Dun-
can would be a different matter entirely!  Anyways, I checked with the folks
at Exact Miniatures and they confirmed that SuperShips used to sell a "giant"
carrier capable of landing a single small R/C airplane on it.  By the way,
they also mentioned that SuperShips still exists, but they only sell one
ship class: a Fletcher destroyer.

By the way, I'm still looking for the address to SuperShips.  Anybody know
their new address?  Thanks for the comments Duncan, they are greatly appre-
ciated.

I've got the same setup. Only one needle turn is too lean. I run mine
somewhere around two. If you've run three gallons with that setting,
you may not be able to salvage the engine. The chattering noise could
also be slop in the connecting rod - a result of too much friction
caused by overheating.

You could try to run the engine on a test stand for a while. If
you put through a tank or two with it running bubbly-rich, you
may be able to leave enough carbon deposits to bring the compression
back to useable levels. This does sometimes work, but no guarantees.
This would only fix a piston / piston liner compression problem - 
not damaged bearings or conrod clearance problems.

You should watch the exhaust from your engine. If you don't see
some smoke, it's too lean. You can develop an ear for the the
exhaust sound, too.

Good luck!

ON SMOOTH TRACKS BECAUSE OF THERE WEIGHT DIFFERENCE.

LINES OF THE BOLINK SPORT TRUCK.  IT HAS A PAN TYPE CHASSIS  AND WAS
DESIGN FOR RECREATIONAL USE.  DON'T TRY USING IT IN YOUR GRAVEL DOORYARD
THOUGH!  IT WAS DESIGNED FOR USE ON SMOOTH PARKING LOTS AND THE SUCH.
THE BOLINK TRUCK COULD POSSIBLY BE A COMPETIVE CAR AT AN ONROAD TRACK.
I HAVE NEVER SEEN ANYONE USE ONE THOUGH.
   I RACE 1/10TH SCALE ELECTRIC ONROAD.  I HAVE A C&M COBRA LTOOR.  I
ALSO HAVE A COBRA SPORT FOR MY RECREATIONAL USE.  I USE IT IN PARKING
LOTS AND TENNIS COURTS.  I PERSONALLY WOULD NEVER TRY USING THE SAME

Yup... the motor(s) must remain with the airplane. I think they also 
added a "G" total impulse limitation and a weight limit (with, I think,
the "escape clause" that the rocket motor is the "primary means of pro-
pulsion"). 

I suppose 5 pounds of thrust isn't all that much if you are into the

(Believe it or not there are people who do this.. the airplanes can

If it's the same amplifier I'm thinking of, it is really an antique design.  It
used germanium transistors instead of silicon transistors.  Even when they were
not antiques, Ge power transistors were expensive.  They weren't any bigger
than Si transistors though they were typically in the same physical packages -
just considerably different internally.
 
The OP amps you are refering to were probably hybrid or potted descrete
component devices.  Until the menufacturing techniques for IC's were refined,
the only way to get a really good instrumentation amp was to build them
descretely - they were often potted to provide a more uniforn temperature
environment.  I remember working with some that looked like tubes (valves for
you Brits) complete with 8-pin octal bases.

I have a copy of the boosted Arcas film that was put together for NARAM-31

Hellmund (now at Estes) may have had some involvement as well.

Ken Brown (Qualified Competition Rockets)

Springfield, VA  22150

[Trip is based out of Charleston, but Ken should know how to get in
touch with him]

My copy is already second generation. I have made a copy or two of it, but
my 2nd VCR bit the big one since then--even before that, the copies weren't
very good.

Well, they could use the old style polaroids.. the ones

Or build a little compartment to catch the photos?

I have purchased a number of QCR competition kits and entered them in 
quite a number of meets.  In my opinion they are the best way to start
out in competition.  Ken Brown has done an excellent job of putting together
kits for just about every competitive event.  Since all of Ken's kits are
made from parts that are readily available its fairly easy to make your
own versions once you have built one of his.  In some cases though I find
it easier to buy from him, especially for things like helo duration models.

   On this subject, does anyone have any suggestions/recomendations for systems
to provide positive retention of the motor in the motor mount.  Something like
the motor hooks used in 18 and 24mm motor mounts, only larger.  Are such things
available or do you have to roll your own.  Every time I tape a reloadable in
one of my rockets I think "What if I didn't secure it well enough and it blows
out instead of deploying the chute?".  If that happens then the rocket is
destroyed (prang!) and the reloadable motor is lost and/or destroyed falling
from a great height.  I'm trying to think of some clever system to ensure that
this doesn't happen and thought that other folks have probably had these same
problems and may have worked out solutions.

   Thanks for your assistance.

Just think of the damage to you if it had hit you!  I thought all HP stuff
was launched a few degrees off vertical in a direction away from the 
spectators area just in case of a recovery failure. Granted, I've seen
stuff pointed straight up decide to turn 30 degrees and stuff launched
with quite an angle decide to go straight up, but I was wondering if
anyone who went to LDRS knows what steps are taken to prevent rockets
from doing core samples through your head.
