Don't you mean torque? As I understood it if you've got the prop spinning one way, the rest of the airplane wants to go the other way and the height of the fuselage and the tailplane helps counteract that.

I could believe turbulence is a factor, though, since a bubble canopy might create a small vortex just behind the bubble, which might cause buffeting of the elevators and horizontal portions of the tail.
