That's where I'd start if you brought me the helicopter. I go to the FIRST LINK and read the paper to get a good understanding of how the little wonders work.
Then I'd remove the blades and flybar and spin up each shaft to the good from the bad. Most anything bent can be straightened, but to try to get the little bird to fly by fixing the wrong thing is a waste of time and a huge frustration. The Setup Guide takes you through each step to determine that each sub-assembly is running true and properly. You'll build the helicopter rotating assemblies a bit at a time and verify each step. I also included tips on how to repair what doesn't work correctly. When all of the parts work as they should you will be a LOT closer to flying again. Going through the entire guide to set it up takes maybe an hour. There's nothing complex about it. And it will take little more than a screwdriver and the proper allen wrench to set it up.
IF you have messed with the screw pots in the 3 in 1, you'll have to ask the guys on the forum about how to set those. Mine are still original. But don't hesitate to return, let the forum know that you have all of the spinning assemblies set per the guide and all that's left is to tweak the pots.
Heck, with everything in good order, you may get the pots set without any help.
Remember that this is a fun hobby - not a job. Have fun with it. You'll survive it all, and you'll have stories to tell when you're done. We've all been there.

wow, sorry about your luck. i have seen some people on here having problems with their motors right out of the box. i wouldnt have any idea of what to tell you. you wouldnt happpen to have the crash on video do you? kinda morbid i know, but sounds pretty dramatic.

i wish i had the crash on video, would have been cool. i had seen gas airplanes catch on fire but never a battery one.. Soloboss, thanks for the tip, i watched the video and happen to notice that my engine plugs were backwards, i fixed it and it hovers again.. Thanks guys for your help
