I've been struggling with stripping gears and breaking pinions on my 550e. My best theory is that there is just too much frame flex between the motor and main gear. I came across a very cool new frame brace at GrandRC today and figured I'd give it a try. It connects the lower bearing block to the motor mount, giving it way more rigidity and a fixed inflexible mesh.

Only a couple flights with it so far, but I have high hopes that my chronic stripping issue is behind me.

i ended up installing a 700 nitro main gear and a revco 18 tooth pinion.

then started stripping tail gears. all good with the 600 boom and belt. so far.

The thought has crossed my mind and I may still go there. But either way this seems to really stiffen up the frames in the high stress area of the frame. Still running the stock 1.6mm which has too much give near the motor and main shaft IMO.

yes. the 2mm frames make a huge difference with a high torque motor.

i also installed the kde frame stiffener. made a difference.

Looks nice but a bit much $$ for this mod but I think a set of 2.0MM frames would be much better. I have the stock CF frames with the KDE rear stiffener and center frame support and it seems ok. My buddy has the 2.0MM frames and its very firm with minimal flex and its well worth the upgrade for only $99 bucks and the Custom Heliparts 2.0MM frames have the center drilled out for the third bearing block if you want.
