Okay--so 475 on the ailerons. Probably an 8101, 4731, or 4721 on the rudder--just because I got so many and need to use them up. Those are all high torque coreless. Over 100oz at 6V

You think the HS-77 Low Profiles would work if I put 1 on each elevator? They're gonna be about 75oz at 6V.

I usually yank the FW out of these little 40 size planes and replace it with some nice 3/16" hard ply or maybe 1/4" and some bamboo pins and tri-stock. That opens up the front and allows me to get at the tank area. When I mount the engine inverted--I move the tank CL to line up with the carb.

I will take your advice and go inverted on the engine. When I do that--I usually try and run it without any assistance from on-board glow. But, I bought 6 of the RamTek on-board glow units recently--so if it gives me any trouble, I got the cure. Usually--with the tank and carb lined up--I can get away without the supplemental heat from the glow unit.

Using the TH .75 on these little 40 size planes at my altitude seams to be the perfect combination of weight and power for good 3D. The engine weighs less tham most 60 size sport engines and provides the power I need to hover about 6 pounds at 1/2 throttle.
