control throes
 

Is this correct it seems like very little movement?
(I built the sport wing)

“SINGLE RATE TRANSMITTER
The following throws are for a transmitter that does not
have Dual Rates.
PT-40
ELEVATOR 1/4" up 1/4" down
RUDDER 1/4" right 1/4" left
AILERONS 7/16"up 1/4" down
Note: The balance and control throws for the PT have
been thoroughly tested and represent the settings at
which the PT flies best. Please set up your PT to the
specifications listed. If, after a few flights, you would
like to adjust the throws to suit your taste, that’s fine.”

The GP instruction manuals are generally right on the money. I'd go with those throws. The last thing you want is a trainer that's all twitchy and easy to over-control.

I maidened an aerobatic plane last week using control throws that "looked right". I had way too much aileron and elevator on low rates. The first minute or so of the flight was pretty hairy. You can always change them down the road after you have some time on the plane.

Chuck: the nice feature of dual rates is your ability to set the maximum throws the way you think they should be then reduce them by about 1/2 for low rate. That should give you the margin of safety to fly successfully on the maiden. After the 1st flight you can then tweak them to your satisfaction. Of course you CG location should always be considered as well.

TedMo, I understand the Original Poster to be stating he is using a single rate transmitter, so he needs to have the throws for at least aileron and elevator close, as he has no ability to reduce with dual rates. 1/4th inch would seem to little for rudder. However, if that's what GP is saying, go with their recommened throws. Wzak29, please confirm that what you have stated as Great Planes recommended throws, are what they recommend.

Yes, I know. Been using my radio for quite a while.:D On the plane I mentioned, I actually set the low rates at 40% of the high and the elevator and aileron were still too much.

My point to the original poster was that too much throw would not be a good thing. In my example I managed to fly the plane safely because I've been at it a few years and I knew to relax and be gentle on the sticks until I could land and make the needed adjustments. A complete beginner might not be so lucky however.

That bring sup another good point for beginners... until you are absolutely comfortable with your skills, always let someone with more experience maiden the airplane. There's no worse feeling than losing a nice plane on the first flight.

I agree that you should leave them as suggested in the manual and fly the plane. You can always adjust later if you feel necessary.

RE: control throes
 

This is one area where following the instructions is a good idea.

You are right guess I overlooked that and was replying to Chuck sorry.

RE: control throes
 

these are great planes throws and I don't have duel rates

RE: control throes
 

Like everyone has said, use the throws listed in your manual or at least get them as close as you possibly can by adjusting the pushrod position on the servo arm and maybe the control surface horn if necessary.

Your radio will work great for the PT-40. No need for dual rates.
