I was wondering if anyone can give me recommendations on modifying my "new"
Heli-Boy 222 helicopter.  I received it, partially built (it was sitting in
a storeroom for about 10 years :-), and I stripped it down to bare parts,
cleaned them all, and I am now in the process of reassembling it.  I would
like to make a few modifications to make my life more simple, since this is
my first heli (I have 4 fixed wings).

The first modification I want to make is adding a fifth servo so I can have
separate throttle control (currently uses a mechanical linkage - I plan on
getting a Futaba 7UHP which has mixing etc...)  This addition requires
rebuilding the servo mounts (which were precut in 1/8" plywood).  I was
thinking instead of cutting new mounts out of new plywood, I would attempt
to build up one out of fiberglass or carbon fiber (I have experience in
glassing, so this wouldn't be too much of a problem).  Any suggestions as
to the sanity of a project like this?

As for the second modification, I was going to add a gyro to the tail rotor
so as to make my life simpler learning to fly.  What kind of gyro should I
purchase?  There are four different models from Futaba, and they all seem
similar in functionality, at least from their limited descriptions.  What
is the true differences?  Is there one that is more preferable that the
other?  

Any other suggestions?  So far my reconstruction has been pretty straight
forward and simple, but I would like to head off any problems before they
occur.  Thanks for any help you can give.

I am approaching the completion of my first model now. It is just a question
of a final sanding and then covering. It is a `traditional' all balsa
glider, which I intend to add a power pod to. I am thinking of covering it
in a heat shrink film, but their seem to be so many to choose from
(SOLARFILM, SOLARTRIM, LITESPAN, SOLARTEX, SOLARSPAN, GLOSSTEX).

What I would like to know is which of the above should I use, and how do I go
about covering it. My kit has no instructions on it?

Thanks in advance,

 Tim

The vacuum pump does not get all the nasty heavy resin out. You should not 
be applying excess resin in the first place. The fabric is wet with resin 
but there are no puddles of resin.

There are strength advantages to heat cured epoxies but there are plenty of 
good quality room temp cure epoxies available. The only reason these would 
be a problem is if you want to leave a carbon fiber layup unfinished. The 
surface temp might reach 140F in the sun. This is getting on the high end 
for room temp cure epoxy.

I disagree with the "tortuous path" comment. I spend much less time building 
with vacuum bagging than I would with a built up wing. Conventional 
construction is the tortuous path for me. Several of the composite companies 
offer cloths and epoxy at very reasonable prices, not the hobby shop prices 
you see for small packages of fiberglass.

Ken,  I have experienced the same problems you describe.  In both cases
the problem was the TRANSMITTER not the car or it's electrics.  My PCM
and Magnum Jr both had the same failure.  The steering wheel turns a
potentiometer that is mounted to a piece of plastic that is "welded" in
place at the factory.  These "welds" (melted spots - "melds"???) break and
allow the potentiometer to float around what should be the centerpoint.
You can verify this by opening the radio and watch the plastic mount as you
turn the wheel.  Be careful.  It's easy to fix.

I fixed both radios using CA to glue the plastic mounting piece back in it's
original position.  Don't worry if it's not perfectly centered as you can
change use the Steering Trim control to center the steering, (get it close
or you will run out of trim capability.)

You can also send the radio back to Futaba.

Good luck and let us know if you have any luck.

I fail to understand all the mathematical complexity of RC radio interference
problems. While it is true that intermodulation products could cause a problem,
and that certain mathematical relationships could cause unwanted signals to
pop up in the IF, there are much simpler explanations that are not considered.

You experience above may have been simply that the transmitter you flew too
close to overloaded your receiver. It really wouldn't matter what frequency
he was on, just as long as the signal saturated the front end (or the
intermediate stages) of the receiver. Perhaps the signal got into the
servo wiring. Who knows? 

I had a guy at the flying field tell me not to stand too close to 
another transmitter (I was within 10 feet). He indicated that if you stand
closer than 20 feet, it causes intermod.

Well, I KNOW that intermod is a RECEIVER phenominon. But this guy swore that
he'd seen it cause trouble. What was probably happening was simply that
one transmitters signal was overloading the internal circuitry of another.
Whatever the fancy explanation, I moved over 10 feet.

Of course, then there are the radio glitches which are actually caused by
severe air currents....

I would disagree that polyhedral makes a ship non competitive. Practice 
is really what makes a sailplane competitive. It just happens that the 
better pilots like a ship that responds better and isn't as easy to fly. If 
you have 10 minute maxes to make and the air is good, it's easier to thermal 
inverted with the aileron planes. Doing a nice circle at high altitude 
inverted is just a pain on a poly ship.

The alcyone looks good, only seen one or two.  Probably one of the best is 
Agnews Banshee.  E387 gives it a good speed range and it slows down 
too.

Are the tips of ships like the Falcon, Legend, etc polyhedrals?

Heh.. *rueful grin*

I go through bags of plugs every year. In my case "cheaper is better" 
seems to work - I use the Fox Std. Long for most things. I'll have to 
try some other plugs though... maybe I'll find something that lasts 
more than one or two flights.

With a glider, you always have the Tx in one hand and plane in the other
for a breif time, whether it's hi-start, winch, or electric-assist
launch.  As long as the plane is trimmed properly, and you throw it
level, you'll have lots of time to transfer the Tx before things get
hairy.

I did :-)

Actually - it was a stretch to call us the DEC Soaring team.
I think they were also doing team scoring so we naturally said
OK - we're a team and signed up.

In fact there was yet another DECie 50 feet away when the picture was
taken and in the New England area there are quite a large number
of us DEC R/Cers talking over our network and flying together.

Watch for one of our members to have his Combat Gremlin plans published
in next months RCM.

As an aside there is a quasi official DEC club (DECRCM (also called the
HTA gang (but that's another longer story))) that meets regularly
and officially so that we are recognized by the company.  This only
gives us official blessing of the use of the company's computers and
internal mail system and etc.

As a double aside - the picture of my Lovesong is the last picture.
A few weeks after the NATS I blew the stab on winch and after spending
most of the contest getting it out of the tree (we finally cut the tree down)
it is really broken up.

As a triple aside - just kidding!

I haven't built or flown the kit myself, but the designer, the "Old

fly them here, most notably Dave himself.  Dave is an inveterate
tinkerer, so what he actually flies isn't necessarily the same as the
kit.  He tinkers with airfoils a lot (doesn't the kit have a Clark Y?).

It looks the way it does because Dave likes the look (sort of 30's
German full-size).  It flies just fine, but Dave doesn't win big
contests with it against hot pilots flying the latest designs.

I don't think Thornburg even puts spoilers on his, but he is still very
consistent with his landings.  He practices them more than anybody else
I know, though.

If you like the look, build the kit.  It flies well, but you shouldn't
expect the performance you can get from a Legend or Alcyone.

I, too, have just finished my Electra and have flown it with success.  I added
the optional landing gear (cost about $3 and 10 minutes of time) and wing
skids, which are useless since the horizontal stabilizer scrapes before the
wings do.

On one of my flights, I had a crash on takeoff (no damage to the plane, thank
God), which I assumed was caused by a low-speed stall because I didn't throw
it hard enough.  Since then, I throw it as hard as I can with one hand and
have had none of the instability problems that you've had.

Incidentally, I,too, was concerned about have the tx in one hand while throwing
the plane and having it crash before I could get my other hand on the controls.
I have in the past flown powered planes which take off from the ground and
couldn't imagine the hell I'd have if the transmitter wasn't in my hands at all
times.  But, in my admittedly brief experience with the Electra, I've never even
noticed that I didn't have the tx there at all times, and as soon as I've needed
to adjust the controls (which was within nanoseconds for the first, untrimmed,
flight), it's always been there.  Somehow, without any conscious effort on my
part, it magically moves into position.

I live in Colorado, and the model flies quite well under power, but with the
heavy battery packs it has a steeper glide ratio than I'd like.  All-in-all, 
though, it's a very good and very easy to build plane.

In general, the faster you can throw it (safely) the better.  Are you starting
the motor before or after you throw it?  I have a Kyosho Sauris II, and
I start the motor about 2 seconds before throwing it, while I am running
with it.

Other than that, if it stabalizes within a few seconds I don't think that
you have much of a problem.

You might want to check with one of the stores that carry video games or pc game software.
I think there is a throttle foot control on the market for one or more of these games. You

Hi

I was told NOT to throw it, but to keep the nose horizontal and let
go.  Throwingit I was told can cause th plane to outrun the
hi-start in the first few seconds (depending on the throw) and that
is bad.  But I am a beginner at this, having myself launched for
the first time on Saturday.  I ony had one abort and that was my fault,
not holding it correctly with nose down.  Otherwise I had a friend hold
