I used just regular rubbing alcohol, of 70% strength.  No special reagent
grade (too expensive, and hard to find), but I suppose that it wouldn't
hurt if you have it around.  I don't know if ethanol or any similar -ol
would work.  Guess it depends on the chemistry of the epoxy.

     I wish those were the only symptoms that developed.  After using CA
for a couple of years and suffering no ill effects, I developed an
allergy to CA glue. My symptoms are much the same, with a couple of ugly
twists.  In addtion to itchy,weepy eyes and a nose that runs like
a faucet, I sneeze enough to make it hard to catch my breath, which is 
difficult anyways because of the tightness in my chest (somewhat like
a very gravitationaly challenged person sitting on your chest). I
have suffered through a couple of these events, and they scared me enough
to give away my CA's. I might add that I'm not that old and in general
am quite robust - not someone who should worry about wether he has
just done something that will actually make his heart stop.
     Just my experience, haven't heard of anyone else in my area that has
had any trouble.

If it was that humid, there may have been enough moisture to cause a
partial short somewhere; especially if you brought your car in from
outside were it was colder, as this would cause some condensation. If
there is nothing wrong mechanically, maybe you just need to put the car
back together and see if you can get 4 minute runs again. If your run
times are still shorter, switch back to your old charger (assuming you
still have it). You'll either find your problem (the new charger), or
eliminate one more possibility.

Sorry to use MODELS.RC for this post, but I'm not sure where
to put it.

I went to an indoor rubber powered meeting last night.  I was
really impressed.  I noticed that most of the guys were power
RC fliers taking to rubber power for the winter.

One of the designers from from MIDWEST models was there.  He
had the ultra-light film planes as well as good flying flat paper
profile planes.

I am looking for suggestions for which type of rubber power plane
I should build first.  Are there any HP plotter plans out there?

Thanks

RS232 describes the physical method of sending digital data over a serial
communications line; it does not prescribe the actual information being
sent/received.  Questions of baud rate, character length, parity,
character set, etc. must be addressed.  Then the format of the data must
be described.

The radio outputs a variable resistance for each of it's channels.  This
value must be measured and converted to digital format for transmission
on the RS232 line.  A circuit could be built to accomplish this, but the
interface requirements would have to be documented.

>Then, I could use it with a flight simulator.

If so, then you need to know the baud rate and protocol for the particular
software package.

Model Netters,

Does anybody know how to convert a Futaba Attack-4 radio so that it
outputs RS232 in place of it's radio signal? Then, I could use it with
a flight simulator.  Also, I'd like it to be easily reversible back to
it's regular radio functionality.

Gee, Taib, I can't think of many heckuva-deals, but I have a bunch of
war stories.  I've already written a couple of my own here, before, but
here's one from somebody else.

I've got a flying buddy here named Kevin Peterson.  He is one of the most
amazing students I have ever had.  He's been flying for all of three years,
and I have to *work* to outfly him, already.  Life's not fair...

Anyway, this past spring, Kev was out practicing his pattern with his
latest pattern beauty.  First flight of the day, he forgot to plug in
the aileron servo.  Well, for most flyers, that would mean a flyaway if
they were lucky, or a slowroll into the ground if not.  Not Kevin.  He
took off, quickly noticed that he didn't have any roll control, and the
airplane was starting to roll off to the left.  "Oh, oh," says Kevin,
still cool, and feeds in enough right rudder to keep the airplane
climbing, and pulls up the gear.  Now the plane is inverted, and getting
further away, so on the way on over, he pushes down elevator and turns
the still-rolling airplane back toward the field just before it goes
inverted again.  Now, top-rudder in the other direction, and the airplane 
flies back across the field in a pretty-as-you-please slow roll.  He does
a slightly skewed loop in the middle of the field, just to wow the other
fliers, who are standing, staring, disbelieving.  

Nice going, but what now?  He turns the airplane at the end of the field 
again, and starts a huge rolling circle, descending with throttle (but 
going back to full throttle when knife-edge so as to keep the top-rudder 
effective).  He lines up with the runway, inverted, but timed so the 
wheels would be down when he got to the ground.  Nice plan.  But he put 
the gear down, that was the fatal flaw.  The gear wells opening up on the 
knife-edge final somehow caused enough drag to increase the roll-rate to 
where it was knife-edge again when it got to the ground, and he didn't 
have enough power at full throttle to pick the airplane up from a low speed 
knife-edge.  The airplane cartwheeled and came apart.

Add me to the list of box-stock Gentle Lady builders. With standard servos I
needed to add several ounces of weight to the nose; with micro servos the
thing balanced quite nicely with minor fore-and-aft adjustments of the servos.
The plane was more sluggish with the extra weight than it was lighter, but
still flew like a dream. Next up, an Airtronics Eclipse for those days when
the arm's tired and the high start won't.

Epoxy sensitization is definately alive and well. I have a very vivid picture
in my mind of a doctor building his own composite airplane i.e. EAA type
homebuilt, in a full respirated body suit. The picture was in EAA magizine
some years back. I don't remember the exact wording of the accompanying
article but either he was very concerned about sensitization or he was so
sensitive to epoxy that the body suit was a last resort. Obviously he wanted
to build that plane real bad :-)

In conjunction with composite airplane construction and the resulting cases
of epoxy sensitization a product known as SAF-T-POXY was developed
specifically to minimize the sensitization risk. It is still in use and very
popular with the EAA/homebuilt crowd.

Since we're talkin about going from more than 4 minute run times down to 
three minutes, I don't think that track grooming is the key.  This track
is always a sticky, gummy, hard black dirt -- it is almost always the same.

>A wide open course will kill
>batteries quicker than a twisty track.  
 
No, no, no -- not at all.  A more wide open track will allow the motor to
have more average rpms and thus a higher back-emf and thus lower current draw.
Of course, if you are saying that a wider track and a more than correspondingly
lower gear ratio, than that is another matter.

Like I say, the setups were the same as previous successful ones, and
by the way, 3 different battery packs were used with similar results.
I now have the car apart down to about the individual piece and see no
mechanical problems.  The connectors on the ESC seem to clean.  This race
day was only slightly cooler inside the race building than usual, but it was
very humid -- I could see some sort of fogginess across the room.

I think the little Sportsters are fine, actually. I learned to fly on a
Goldberg Eaglet with a K&B Sportster .20. That engine always started and
always ran well. I never had problems with it.

I know that the bigger ones can have problems, but I think the .20 is the
best $40 .20 you can buy.

I won one at a Christmas raffle several years ago. I built mine with a Fox
.15BB, Challenger radio, and Titan mini-servos. The plane was covered with
Mica Film on the wings and silkspan on the fuselage. It came out overweight
and it was no fun to fly. With its small wing area, it lands rather hot.

If you pay attention to weight, it should be okay. As a sport plane, it's
rather limited for aerobatics. I remember it was alot of work to build.

OK people...

What are the best rumors/tall tales/stories you've heard? They
can be true, untrue or unconfirmed - most of these would probably 
involve the proverbial "heckuva deal".

Let me start off with two:


1) At last year's Nats I finally found out the story behind Brat engines. 
   Apparently there was this deal to make a line of ARF's called Brats,
   complete with engines. The engines would have _Brat_ on the casting. 

   Well, the story went, the deal went sour, but several thousand of the
   motors had already been built. So Indy R/C started seeling them.

2) Again at last year's Nats. I was staying at the dorms and a large bull
   session developed in the lounge. I was balancing props (and selling
   glue applicators). Some person (forget his name) with a very nice pro-
   file Su-26 (for C/L Stunt) told us this long tale about how he came 
   across some huge number (3-400) antique balsawood life preservers. 
   These were a plank of balsa maybe three feet long and eight inches 
   square in cross-section. They were waterproofed with paint. 

   The life preservers were part of the equipment of some historic paddle-
   wheel riverboat. The riverboat was being decomissioned and there were
   three or four pallets of these life preservers sitting there. 

   Along comes our hero who goes along thinking that he'd buy ten or twelve
   of these things. He was offered the lot for a couple hundred bucks. He
   was a little leery of the deal so he took one home to saw open on his 
   friend's bandsaw. In his words, it turned out to be "Ecuadoran gold". 
   Absolutely beautiful wood. So now he's got a problem. Where to put it all.
   Well, a friend has a garage. (I forget all the details.. he went into   
   how he was between jobs at the time and had to raise the cash). In any
   case those life preservers supported his hobbies and contest-going for
   years to come, as he sold the water-sogged ones to collectors for $20 
   apiece, and whenever he needed wood he'd haul some to his friend and 
   they'd slice some on the saw....
