I have a .46AX on my PT-40 and I can go straight up indefinitely with it. Not sure what more you would want from a .61.

I made mine with a bolt-on wing. I believe the spars on the PT-40 are spruce, they definitely feel denser and heavier than balsa. The shear webbing is horizontal grain, however... I wish I knew about vertical grain webs when I was building the thing.

Well I am trying to turn a trainer in to a much more aerobatic plane. I want to use the 61 because I do not have a spare 46 to put into it.

I have a 46 FX sitting in another PT-40 it runs well, but there not unlimited vertical with it.

I have made a decision that I am going to make the mods and put the motor in the plane, I will be gentle with it and see what happens. Will let you know how it goes
