RE: Two bolts on main shaft.... special steel or not?
Well, I finally got the screws replaced and I had to replace the feathering shaft. It was a good learning experience. However, when I spin up the motor I still get vibrations. The Tail rotor looked good as well as the servo gears. I don't see any obvious signs of a a bent main shaft. Do you think that could still be it? What else should I look for? Also, I've been practicing on the Phoenix flight sim. I've learned that on the simulator, the heli wants to go foward and left. My helicopter seems to want to go back and to the right. I don't remember how it was before the damage. Should the flight sim be pretty simular to the the real thing?
Thanks in advance,
Robert
Turns out the shaft was bent. However, it still seems different than the sim.
