The 80" profile with a slightly underpowered and overweight quadra 35 did a deadstick/nose plant while hovering at 40 feet. Now the flywheel is running crooked to the crankshaft and the small plastic cover under the flywheel is loose. I think it's time to replace the engine (after refreshing my building skills). What would you recommend with a little more power and less weight. (this is one of the original Q35 engines but I have not wieghed it it's heavy)

Also, how is the flywheel removed? I want to see what the problem is and try to repair the engine, but don't wanna spend much doing it.
