Hey guys could anyone help me out on the plans for the wing section of this
Top Flite P39. I bought this kit about 2 years ago and have just now started
it up again. Some how in a move I have misplaced the wing plan. I will pay
for shipping + a reasonable amount for the plan.

Is this for real or some disgruntalled employee or customer?

Anyone tried a micro z-72 antenna on their GWS (or other) receiver?
They claim better range than the stock antenna.  I'm looking for a
shorter antenna w/o sacrificing range.

Howdy!
Been flying my SIG LT40 for almost a year, and this last weekend managed
to stuff it face first into the ground. :-(
Don't ask.  Pilot error.  The crash looked remarkably similar to that

What is the best way to waterproof a servo. Just recieved my first pair of

I need to do to waterproof my servo's?
I assume I wrap my RX in a bag and seal with wax?

Have a cowl that is not quite wide enough for a twin cylinder engine, the
spark plugs will stick out about 3/8 inches on each side and would like to
find some streamlined "bubbles/air scoops" that I could put over the holes

will turn at various rpms and I wondered if anyone knows a web site that

How do you establish a centered/neutral position for the ailerons on a

Flashed up t'internet connection and ordered an OS engine from
Blackburnmodel.com. Time of placing order 15.20 yesterday.

Do the turbulators on a full size aircraft make the air flow break away
during slow speeds thus making the inner wing stall at the same time as the
tip?
Would a model aircraft prone to tip stalling benefit from turbulators?

Can anyone tell me why APC electric props have such a wide chord and
reduced thickness cf the sport type props in the range ?  Is there any
reason to avoid the sport props for electric use ?  (I know they don't

balsa). Can anyone point me in the right direction?
