Just thought I would share some of my ideas for getting the main gear shaft of the blade cp true again. If you have access to a lathe a 1/8" 5c collet will hold the shaft. Grip the shaft in the collet then place a .001 dial indicator over the shaft as you place the lathe in neutral and rotate the gear shaft by hand to the high point on the indicator. apply slight pressure using the plastic hub that extends past the gear. repeat this until the shaft runs true again I can get it down to .001 of an inch true. Another idea is to use vee blocks and a magnetic base indicator if you don't have access to a lathe. other people have used a bridgeport milling machine with 1/8'R8 collet. Of course buy another for a spare but don't throw away your bent gear shaft until you give this a try. Have fun flying!
