Wow! Great info here! I too have a H-9 PT-19 that has not been flown yet.

I was wondering about that CG of 4 13/16 in the instruction man. Seems to be right so I will balance this plane with that CG. It has a G-23 that has never been cranked yet, I will post a pic later. I took the info on the landing gear and may have to open up the wing and fix it too-may go ahead and put the Robart strutts on it anyway.

Thanks! SRCP
