OV10 25's
Do you have the arf kit, if so the right engine has a shim for left thrust or offset to the left what ever you want to call it, the left engine was o degs, control throws should be about 1/4" for all until you get to know the airplane, I do not remember the CG I thank it was 4" from the leading edge, someone should be able to get that for you.
Hope this will help KRANZGoldwings:
