I just ditch my 600 today, and once i got it home, I decided to strip it down to see what was broken.
Thought i would share some of the things a look for when taking apart a broken helicopter.
Have two boxes. 1 for good parts and 1 for broken parts.
A trick for finding out if you have a bent feather shaft is to, take the two blade grip ball links ( or control arms in my case) Hold them together, then rotate the feather shaft with an allen key in one end. If the shaft is bent, you will see movement in the ball links or arms.
This can be done with the tail as well to check the centre hub.
Take the main shaft out and on a clean glass surface ( i used the cooker) roll the shaft across it. If it wobble across then its bent.
Check each bearing for grittiness. A sign of damage. Mine where fine except one that got mud in it. I managed to clean it out with some silicone spray.
Turn all the servos by hand to there limits. If you feel crunching, you have broken gears inside.
Check linkages for damage. Bent arms or broken ball links.
Check all wires for damage.
If its a belt drive, check the belt for fraying or damaged teeth.
Check main and auto gears for damaged teeth and (torque tube tail gears) if you have torque tube drive.
Check blades for damage. Some may be obvious, but some may be stress fractures you cannot see. Give them a slight bend to see or feel if theres a problem.
There are many other things to check like electronics. They can be done on the rebuild.
Feel free to add anything else you think of. Or top tips.
