Just wondering could i put a OS46AX on my Cougar2000. I have been unlucky with the Weston UK 36. The 36 combo with the pipe gives brilliant performance, but hasnt been reliable for me.(shearing crankshafts and the like).

Thanks

No problem with that setup. Mine is done this way.
You only need to put the rudder servo on top of the fuselage, just in front of the vertical fin, to compensate the heavier engine in the nose

Thanks .What size prop are you using? Been using a 11x4 on the Weston.

Correction, I'm using an OS46FX, not AX, but that wouldn't make any difference i guess.
Prop is a APC 12x4 sport, or APC 12.25x3.75
