The smallest R/C (remotely controlled) plane I have seen fly is a Peck-Polymers
Prarie Bird with a C02 engine and rudder control.  I believe the airborne
pack was a custom made unit, not commercially available.  A fellow
club member built one after being inspired to fly R/C during the rainy season.
The intent was to fly indoors, but that was near the begining of the
drought we have had here California for the last few years, so most of
the flights I saw were outdoors.

The Prairie Bird is a 16" wingspan Embryo class rubber powered plane.
Obviously, this model only flew under special conditions, like no wind :-),
but it was fun to try and make it go where you wanted.  Mostly the
flights I saw consisted of tossing the plane into the air and keeping it
from flying too far away.  Not terribly exiting.

I have heard of smaller models, a Peanut size SE5a, but I don't remember
specifics.  Peanut size is 13" wingspan.  I have also seen pictures
of very small gas engines, around .003 ci displacement.

If you want to try something that has been around for a while, go find
a "Littlest Stick" kit by Peck Polymers.  It is an .010 - .020
powered 18" span model that with ultra-light gear flyes ok.  Again,
a friend had one with an .020 Cox and a Cannon set-up with rudder
and elevator.  It is sort of like flying a gnat, but it can be called
a pilotable combination.

The smallest commercially available R/C cars I have seen are the 
Tamiya Tamtech series which came out about 3-4 years ago.  These
were 1/24 scale models with custom R/C gear that sold for about
$150-$200 complete, including radio, batteries, charger, etc...

Thery were popular for a while, but I think they have gone out of
production, at least I don't see any more adds for them.

Organization: Indiana University

<Problems caused by bad glow plugs deleted>

The platinum in the glowplug element is important because it 
catalyses the combustion.

It could very well be poisoning of the platinum by something in 
the fuel. Have you switched fuel brands recently? 

I never notice anything like this because I burn out plugs almost
every run  9-)

It could also be a bad batch of element wire - not so much the mix-
ture of the alloy but maybe it comes "pre-poisoned"...

We use platinum wire in a O2 -> CO2 converter in an apparatus we use
to extract oxygen from rocks. Once in a while someone will goof up 
and let some waste gases through to the converter and the platinum 
gets poisoned. Often we can reactivate it by scraping with sandpaper,
but often the contaminant has permeated the wire (apparently Pt is 
pretty permeable). We believe the contaminant is NiF. 

By the way, if your liner has worn down to the brass, or even if you 
have an iron piston/liner that is somewhat worn, you can send it off
for "chroming". A few people do this. Bob Oge comes to mind. I'll have
to dig up his address... we visited his house during the big Chicago 
thousand dollar meet two weekends ago, so I got to see his chroming 
setup. 

He'll chrome the liner and hone it to fit the piston. I believe on 
iron piston/liner sets he chromes the piston as well. I don't think 
its too expensive.. it used to be $15 back in 1983 and is probably
in the $30 range now.

He'll also do all kinds of engine work. He'll make your Brand X pylon
motor go like stink, too, if you're willing to cough up some cash...

Hi all.
  I just acquired a small box full of old Cannon micro R/C
components, including servos and receivers enough to outfit
two planes.  Unfortunately, the transmitter was not among
them.  Assuming that this system is AM, I am now looking for
an AM transmitter, four channels or more.  It should be in
good shape, and a gold sticker is a plus, but not a must.
If it's on 72.080, that's be even better, as it would save
me the cost of a new Tx crystal.  Please e-mail me with a

Oliver - As an old carrier sailor (USS Bon Homme Richard, CVA-31, 1966/67),
it sounds to me like someone is pulling your chain. To launch and retrieve
model airplanes would require a L A R G E model carrier. We're talking
long and wide and we're talking lots of water. Mooring fees. Master's
rating for the captain. In order to achieve the utmost in realism, you're
going to need an operating steam catapult. And a landing signals officer
and LSO board. Mid-air tanking. Alpha strikes.

All of this may be practical from a financial or technical standpoint, but
what is your wife going to say when you go out flying on Saturday and don't
come back for 9-10 months.

Someone should point out that there *is* a widely
marketed rc sub; they sell them at Toys R Us, and they're
in all sorts of gadget catalogs.  They cost around $150, and
come with their own radio setup.  It's a neat looking little
sub about 2 feet long, and it runs on C batteries (I think).
You adjust the ballast until the thing just floats.  You can
cruise around on the surface with right-left rudder control,
and you can dive by pressing a button which turns on a small
motor on the bottom with a downward pointing prop; this 
pulls the sub under.  It is intended to dive down about a foot or so,
but will in fact go all the way to the bottom of the pool (or whatever)
but I've had trouble getting it back up.  I think some air spaces 
inside are compressing, and it's becomming negatively buoyant,
so it just sits there on the bottom.  A friend of mine has one and
we play with it in his pool. Lots of fun, but it's really more a
toy than a model.

    I do a LOT of flight instructing and I am a firm believer of making the first plane
    either an all wood ARF or some used trainer.    Most beginers are very nervous
    especially if they just spent weeks or months building thier first plane.   I find
    that the time it takes someone to learn to land is proportional to the amount of
    nervousness they feel.   If they are flying a plane without a great amount of
    emotional investment they are not nearly as nervous.   I normaly have someone
    landing an old beater within a couple days.   I have others that I know could do
    it but are so nervous that weeks later they still can't land because they think
    they'll dork thier plane.   And maybe they will, but that's why I believe in
    AFS or beaters for the first plane.....
    I try to ween the student from depending too much on the instuctor as soon as I
    have them flying horizontal figure 8's without gaining  or loosing altitude in
    the turns.   I don't like instructing a student to land with a buddy cord but
    if they INSIST that it's OK then I do.   Most of the students that do insist have
    the right frame of mind anyway to do thier first landing.
    Several times during the first landing I'll say to try and get the plane lined
    up for the landing and I'll take over and do the actual landing.   This relieves
    the student and makes the approach without being too nervous.   Some have done
    such a good job that I talk them through the landing without letting them know
    they are still in control.   They make nearly perfect landings then I tell them
    that I never took control and that they did it them selves and they go 'No Way!'.
    Yes way Dude!   I tell them that the key is to relax and feel the plane.   It
    still takes a while for them to really relax but now they're on the right track.
    It normally takes a few more bumpy landings before they solo but they're not nearly
    as nervous doing it because now they know they can.

Clearly, there are two schools of thought here. I have re-worded the FAQ to
reflect this. I have added this paragraph:

   ARFs vs. kits: this is a matter of opinion, but more people seem to think
   that kits are a better idea for beginners. Pro kits: you get valuable
   building experience and are able to do repairs. Moreover trainers are
   good planes to learn to build as well as to fly, and most of them are
   cheaper than most ARFs. Pro ARFs: you can be flying sooner, and you have
   less emotional investment in the plane so when you crash you don't feel
   as bad.
   However: regardless of what you chose, your chances of a painless
   education are greatly improved if you have an instructor - both for
   building and for flying.

Any discussion, changes or other suggestions? Also, how about some
recommendations for ARF trainers?

A reminder: I don't always have the time to read this group, so if there is
any discussion of either the FAQ or plotfoil, could someone please alert
me?
