Granted the crash bent the hollow shaft almost in an L shape. I unscrewed the gears and the rest of the screws near the swash plate but its still not coming out. Am i missing something?
Normally to remove the outer shaft you need to remove both the gears, and the servo pushrod links from the swashplate. Pull the upper rotor head with the inner shaft out of the outer shaft, then pull out the outer shaft.
When you've had a bad crash like that, and with that much damage check the helicopter over very good for broken parts. You may have damaged the frame also, but check it over good. I would disassemble the helicopter, but pay very good attention to where all the parts go so you know how it goes back together. The outer shaft (hollow) will have to slide through the 2 bearing blocks, lower rotor hub, collar, and the swashplate. If you can get the shaft out of the bearing blocks, then it's just a matter of sliding the rest of the parts off the lower part of the shaft. If the shaft doesn't slide out of the bearing blocks, then it may be easier to remove the bearing blocks from the frame. Some of the parts may not slide over a bent section in the shaft, so it would be best to cut the shaft if need be, then slide the parts off. Remember to check the set screws of the lower rotor hub, and the upper gear for being sheared off. You will need to pitch the blade holder for the lower rotor to remove the set screws in the lower rotor hub. Good luck, and if you need more help just ask away.
