Hangar 9 PT-19 CG help please
I have a large hangar 9 PT-19 that I picked up cheap. It's assembled but unflown and no engine mount or instructions.
I need to know the following-
Where's the center of gravity?
What is the CG range and where does it fly best?
What are the recommended control throws both low and high?
Using a TT 120 two stroke in it, going to invert it and rig up some kind of manifold system off the pitts muffler to dump the exhaust down.
Has anybody flown one of these Large PT-19's?
How do they fly?
I appreciate all your help in advance, Thank you all.

H9 PT-19
I flew mine with a Zenoah G-23 and the other two at my field used Saito 150 engines. The Saito powered PT's were faster and the engine's were easier to install due to the narrow cowl.
I don't recall the CG measurement but start at the spar and check your trims after the first flight.
These things are so stable I could do wide open throttle touch & goes. On landing, bring it in with a little power, go to idle at the end of the runway, set it down on the mains and let it roll out.
Don't try a three pointer, they get sloppy, you can do it but there not as pretty. If the planes has the factory wheels still on it replace them with Dubro 4 1/2 " treaded tires with the grey spoked wheels. The supplied wheels are too big and I installed Dubro olio struts made for this plane.
As far as the controls go, I set everything to max throw and cut them in half with duel rate or you can use expo if you like.
I flew on high rate aileron all the time.
Send me your address and I'll send you the engine mounts, you supply the nuts and bolts. Chuck
