Hmmm. I did say that I hadn't got around to actually trying it...
One could take the brut force approach and stick the circuit inside
a fully enclosed metal box with shielded connecting wires. Otherwise
a bit (lot?) of knowledge and experimentation with noise reduction
techniques would be required. Considering the amount of electronic
thing-ies inside a modern radio it must be possible to suppress the
RF, but probably not easy.... :-(
A PCB (not veroboard) with ground plane would probably be essential.

I never owned a Kraft myself, but did build two Heathkit radios.  They
were essentially a Kraft in kit form.  At the time, they were really
good units.  Let's see, $200 got you a 5 channel radio, AM, no servo reverse,
basic square box construction, no dual rates, and you had to build it
yourself!  As we all know, things have come a long way!

If this vacuum resservoir is a bottle you suck vacuum into,
it's very useful. I've built my vacuum bagging system from a
used fridge compressor and a pressurized brake-air bottle from
a truck, and the bottle makes all the difference. The pump
does not have to suck all the time, even if you had a tiny

Ok, lets talk about this. First, it is possible to fly an R/C model
via remote telemetry. Many modelers are doing this now with off the
shelf equipment. One company even has the complete airborne package
along with a superimposed gyro horizon, compass, and airspeed indicator
which can be installed in an appropriatly designed aircraft. Second, it
ain't easy to do this. You will need a safety pilot who can take over
the plane visually if you loose the downlink video. By all means, if
you have the financial means to try this DO IT! This hobby progresses
by the experimentation of brave souls who try something new over the
scoffing and objections of the experts.

Are both wings the same?  It sounds like a little built in washout.  I would
leave it alone.  If you really want to take it out, on a Kadet the covering
should be strong enough.  After you cover it, prop it up to reverse the warp
about the same amount as you have.  Then reshrink the covering and release.
It should be straight.

Hmmm

I think this is backwards. The filament of an incandescent lamp 
doesn't have enough time to cool down enough between cycles, so
it should glow steadily. A fluorescent lamp, however, relies on
the flow of electrons through a mercury vapor through the tube,
and this can respond faster to the cycles of AC. 

Whether they flash 60x per second or 120x per second I don't know.

 If you mean the trailing edge of the wing near the tip is raised .25
inches...and both are the same, you have achieved "washout" which is desirable.
 If only one wing pannel is like this, get out the steam kettle and warp the
wing by hating, twisting and weighting in place till you get it strait.

I prefer to use adjustable clevises on both ends of a pushrod.  I don't trust
any connector with a set screw on anything but throttle.  Also, try not to have 
any bends in a pushrod if at all possible.  In many airplanes the kit shows
the two pushrods parallel to each other with a dog leg bend at the aft end.
Most of the time if you simply cross the rudder and elevator pushrods, you can
keep them absolutely straight.  Much stiffer.  It's probably not terribly important
on a trainer but on a high speed airplane a sloppy elevator can really get
you in trouble.

I don't know exactly who makes them, but the best place I know of to
get one is a windsurf shop.  (I'm a boardsailor, too)  If your net
address is any indication, you're in the East Bay area in CA... If so,
you can go to one of several great windsurfing stores over there, or
come to the peninsula - several good ones here, too.

    This is the terminology used by Futaba in their marketing stuff, but
    is not correct from a technical point of view. The resolution is either
    512 or 1024 POSITIONS, which corresponds to 9 or 10 bits in a control
    word. I really don't know why they came up with this "1024 bit" 
    terminology other than thinking that the word "bit" has a suitably
    high-tech, computer-like connotation.

    Of course this doesn't detract from Kraig's fine explanation of the
    operation of receiver/servo subsystems, but I did want to point out
    how this terminology differs from that accepted in the rest of the
    digital electronics industry.

My RC10 has the old gearbox and I raced it until last October
when I bought a TRX-1.  The RC10 was my first car.  I got it
last May and started racing in August.  Sometime near the beginning
of September I replaced all the bushings with ball bearings.
In the two months before I started racing the TRX-1 I had two
ball bearings in that old gearbox fail.  One seized and melted
the bearing adaptor.  Another was on an idler gear and fell apart,
scattering it's tiny balls all through the gearbox.  I had to
replace the idler gears but all the metal gears were still sound
once I picked the balls out of the teeth.  These were Trinity
bearings and I had done nothing to lubricate them.
I've gotten different opinions on whether or not ball bearings
should be lubricated.

I don't really know the answers to most of the questions, except that
if the endbell is crimped onto the motor can, then changing the timing
(except through timed brushes) may be a challenge.

What is clear, however, is that a motor with 24 degrees of timing has
negative 24 degrees of timing (at least approximately) in reverse.  Some
people also dislike reverse because they feel it unseats their brushes
and thus impairs the next burst of forward.  If you had a motor with zero
degrees of timing, then it should behave well in either direction.
For what it's worth, if you increase the timing from zero to 180 degrees,
you get a "reverse wind" motor.

By the way, I once used a Kyosho Mega motor (22x1) and a Slot Machine motor
for parking lot racing.  Realizing that I would never use the motors in
their present form, I took them apart.  I still have their armatures that
I could put into another motor can if I ever need to do a 12 minute race.
I noticed that the Slot Machine bushings were bronze-looking and decent feeling,
while the Kyosho bushings had a steel color, but were about as soft as bronze,
yet not as smooth.  The Kyosho motor was much easier to tear apart.  The
commutator wear was unlike the wear I am accustomed to in that there were a
few dents, scratches or pits in the copper, FWIW.  I found the Mega motor
to lag behind the Slot Machine, and so I do not know if their 27x1 24 degree
motor would be all that good to worry about tweaking.

Good day,

I bought a vision from Sheldon's about 6 months ago.  They will swap out

(e.g. they give you $15 credit for the 94102's if you apply it to the more
