Crashed my Hawk, bent the feather shaft and fly bar and damaged the blades...so not a really bad crash.

Should the main shaft be replaced anytime one crashes hard enough to bend the feather shaft? Can it be checked for true and reused or if it is not visually out of true reassemble and test fly?

Thanks!

The slightest deviation to the shaft can be difficult to spot. If not located and put in use at 1900 rpm or more will cause the gyros in the FBL to act up. When in doubt, throw it put.

Agree.....if in doubt, throw it away and get a new one. Getting a new shaft will save you for the headache of trying to find the problem.
