Default Flame out on hard landing?

Hello,
I am new to nitro and have been running a Novarossi +4 for 3 weeks now. The +4 has run perfect. I usually have to shut the engine off. Never flames out or dies.

Last night at a club race, the engine died when I let a friend drive it and he overshot the triple and landed hard in the flat. I would never thought twice about it except in the Main I was hit hard in the side by another buggy and the motor stopped again.

Would you consider this a flame out? Or will these motors die from hard impacts?

Thx in advance!

Yes, I had just put a new flywheel on it last night because one of the pins on the associated clutch came out and rubbed on the inside of the clutch bell. So it was a brand new clutch set up last night.

It is possible but wouldnt that have to be a perfect hit on like a rock or something protruding up from the track since the flywheel is above the very bottom of the chassis. I know my flywheel does not stick down below the chassis. But it could happen surprise it has not with my luck lol

Yes! Thanks Maximo, I didnt think of that, but I only have 1mm of clearance between the clutch bell and spur gear. I was told that was normal on the RC8. I can actually flex the chassis and make it touch. Duh! Now I know that is what happened. I guess I am ordering the King Headz RC8 motor mount with the 1.5mm setback. That should solve the problem.

Thanks guys!
