I've been getting 250mah battery packs from Radio Shack, they sell them
as cordless phone replacement parts for about $11.  (Make sure you get
the one with 4 cells.)  You need to reduce the charging current to
about 25ma, some people put a resistor in series with the charging jack
to accomplish that.

As for servos, coreless servos tend to be smaller and faster (and more
expensive), BB servos last longer but don't have any other advantage. 
If you're using micro servos for flaps or ailerons, consider getting
ones with metal gears.  The plastic ones can strip teeth on a rough
landing.  Airtronics 92141 seem to be almost legendary in this role.

It is the RCHTA show at the O'Hare Expo center on Oct. 30 - Nov. 1.
It is a show for manufacters to meet their dealers and the public
though there are no sales allowed. Also have a static display and
indoor demos of cars, boats and heli's. People like Byron's,Robbe
Carl Goldberg,Great Planes etc are there. They also have sections
for tains and plastic models. Friday during the day may be for dealers
only.

   Both servos are the same. The S33 is for older Futaba Radios that use the old

It sounds like your boat is either way out of balance or needs trim
tabs. I got trim tabs for my (cheap) boat since it was having the same
problems. They work good, but are not the best solution if your boat
is really "tail heavy" since they will create extra drag.

Hi!

Since I'm completely new to this newsgroup and couldn't find the answers
to my question's in your FAQ, I'll have to post 'em.

First of all, this is NOT a posting concerning R/C-modells, it's about
free flying scale modells, so if your not interested in the subject, 
stop reading my posting.

The question is :

I've built some of the Guillows balsa scale models that are meant to
be either display object's or free flying models driven by eihter
rubber, 0.10-0.49 cox gas engines or CO2-motors.

So far I've built all my models as display objects so I'm very 
anxious to build a (say a Spitfire) small modell for free flying 
with some kind of ultra small motor and I'm ready to take some advices 
from you experienced gyus about what type of motor I should use.

I've built many (non-scale) rubber-powered planes in my days and I'm 
not interested in rubber anymore.

How difficult is it to maintain and use cox-motors? Are they great fun? 
I've seen people try start these motors (0.8 babe bee's) with a inbuilt 
spring and they weren't too happy looking :-) 

My main interest is in the Tee Dee 0.10 cc (!!!) motor since
I figure the smaller the better is the right idea for small scale
free flight models. Is there any other manufacturers that have similar
motors on their program?

Since I live in Sweden and Sweden is a small country I'm having problems
to find the Tee Dee. I've to import one myself to find out wether it is
the right thing for me, that's one of the reasons that I'm posting here.

CO2-motors are not available in Sweden at the moment, so, please 
tell me anything you know about these things for me, specially 
how they work, if they are difficult to use, if they are
expensive, reliabilty etc ...

Electrical motors. I've been told that electrical motors are far to
heavy (battery package) to be an alternative, but I still hope that
some genius out there has created a package ligth enough for me.

So, my question (plee) to you is too give me advices and information
about these matters.

Please also send adresses to companies that hold these products  so
that I may purchase the objects via mail-order to make my wish come 
through.

Well, the control line flyers have flown their dynajets at Ned Brown 
Forest Preserves in the suburbs of Chicago.  This is a public field 
in Elk Grove Village.  The flyers do not seem to be that concerned 
with noise.  I fly R/C at the same site, and find the open exhaust 
noise of shrieking combat engines more irritating than the occasional 
blast from their dynajets.  The combat planes are loud enough so that 
you cannot hear if your muffled R/C engine is still running.  The 
control line flyers have E-mailed me notes claiming that no one has 
ever complained to Forest Preserve authorities concerning noise of 
model airplanes at this site.  I am not going to complain for fear that 
the field might become off limits to all flyers, noisy and quiet, 
control line and R/C.  The field is quite remote from any residential 
area, and the only people that could be offended by the noise would 
be nearby picnicers and fellow modelers.

  I've been thinking about getting the Dynaflight Bird of Time for
my next project. Has anyone built and flown this kit?
  The Tower and NSP catalogs list the typical BS about how it flies
but I've heard from one of the better pilot's in my area that this
plane is not that great.
  For those of you that don't know what this plane looks like here
it is:  118" Span, rudder, elevator, 1070 sq in. 5-6 oz. wing loading.
The wing planform is most unusual in that the root chord is smaller
than the chord at mid wing. From mid wing to the tip it tapers to an
elliptical tip. 
  I would also like to modify this planform with the addition of
spoilers or preferably flaps. Has anyone tried this?
  Thanks for any input

Hmmm interesting...

There was also one about making wood props for quarter scale. 

Not too long ago many were using glass or carbon props in Combat at
$5-7 a pop, especially in FAI. And you still had to pitch and balance
the pesky things at that price. Now everyone has gone to the APCs. 

I put one on my Combat plane and immediately picked up 5-10 mph...and
they're ony $1.25 each!

There are many off-the-shelf electric setups which have T/W ratios > 1.

For example, I'm using a "Master Airscrew Electric Flight Pak" [ .05
ferrite moror, (2.5:1) gearbox with folding 12 x 8 prop] system that
gives about 22 oz thrust on 7 cells. Motor, gearbox and prop weigh 8
oz. 1500 mAHr batteries (7 cells)  weigh in at about 12 oz. -  System
costs ~$25, mail order w/o batteries.

Expect about 2-3 mins running time at these output levels, plus another
1-2 min at reduced levels with good 1400+ mAHr batteries.

Try a geared cobalt motor, swinging a large prop for even better
performance. 

Look at Hobby Loby's catalogue for their electric heli's. They claim 5+
min flights per battery pack.

All it takes is a very large prop. (Called "blades" on a heli :-)

Well I have not done nose in yet. One way is to put chicken sticks
back on and take off nose in, another go away from you at a slow
speed and turn back towards you trying to bring it to a stop
(you can hit rudder to bail out). A simulator helps here.
As for forward flight a common method is to fly circles around your
self(side view) both directions, once you got this start figure 8's
out in front of you and stretch them out while moving up in

There are many RC boat kits which require glass.  In fact, I think it's
probably a majority.  However, many have pre-built hulls, so someone
else is doing the fiberglassing for you.

A caveat.  Polyester resins do not work well when applied over epoxy.
However, I understand epoxy works fine applied over polyester.

Subject: Help Me Finish My Plane

	I have a Great Planes PT40 Trainer which I never quite finished
building.  I'd like to find someone in Western Pennsylvania who enjoys
building model planes and who would consider finishing mine up for a
reasonable fee, although I'd rather find someone who would do it for the
enjoyment only.
	It needs about 10 hours of work.  I have all of the stick building
done.  It needs the control surfaces, engine, radio, servos, and gas
tank fitted.  It also needs to be balanced and covered.  It would be
nice if this person would take it for a flight or two and trim it out
also.  (I don't know how to fly) I have ALL the parts needed to complete
it.

	EMail me or call (412)268-4458  (The closer to Pittsburgh, the better)
