I'm going to get someone to show me basic rapirs and adjustments. What would you say are the three or four most common repairs/adjustments. For example, I crashed my Cx2 and it now flies all over the place. The fly bar is slightly bent but i dont see how that could cause it to be completely out of control.

I assume you check for bent shafts and stuff before anything else. I'm going to have to learn to repair this stuff myself in order to continue flying $$$
Thanks in advance

Parts
Anything Bent? Replace with new. Anything that spins and is bent is no good. cracked blades? Replace with new. The only thing I have ever seen reused with success is a tail boom from a light strike. Good luck

You would be very surprised how seemingly minor bend can cause major problems. Try and get the flybar straightened out as best you can. The CX2 is great little heli and can take quite a beating. Also, as mentioned in your other thread, check those main shafts. I had to replace mine once. You will figure it out, just hang in there.

Take both sets of blades off and spin them,you will see then if the shafts are bent.

Every crash creates a new set of needed repairs depending on heli and how you crash. after a crash inspect everything if its bent or damaged in any way replace it. if done properly the heli will fly just as it did, if it doesnt you missed something.

This is a tough question because there is no set answer. In general terms.. you should always inspect all flight controls and related parts. Its also a good habbit to power up everything to ensure you have no electornic damage.

Check the brass flybar weights, as I mentioned in your other thread.

If you replaced blades keep them in matched sets. There are small numbers on the root end of the blades. You can not mix and match blades from different packages. An out of balance condition on a CX2 will cause all sorts of stability problems.

I can attest to this. A "what I thought" was a minor crash bent the main shaft and that is exactly how I checked it. Take off the blades and blade gribs so you can see the shaft. Start up the motor and if the shaft is bent at all, you will see it. A bent flybar will make the heli very unstabble as it is constantly shifting weight from side to side. It will probably cost you $4 to fix )
