Hello. I have been in rc for quite a while. A few years ago I decided to get into flying heli's and i bought a raptor 30. I was able to hover pretty well, and without the training gear. However, I had a pretty good crash. I rebuilt the heli and then haven't flown it in a few years. I'm trying to get back into it again and I need some help. I went ahead and fired it up, and when I throttle up, the heli starts shaking pretty bad. I'm afraid to give it more up b/c I think it might crash. I did some reading in some of these forums, and it sounds like my main rotors are out of alignment. One website suggested putting red tape on one rotor and yellow on the other. then spin it up and look a the blades to see if you can see both colors of tape. I can see both colors, and I trid adjusting the link that controls the rotors, but it doesn't seem to help. what other advice can you give me?

I'm also looking to see if there are any other heli pilots in the Charlotte area. I'd really appreciate some help.

Balance everything properly and if you're lacking confidence, get an experienced pilot to lift off and track your blades.

Yea I try my best not to let crashing scare me to much, I just look at it as something to learn from not as loosing the heli since I can just repair it . Whenever I crash I try to recall exactly what happened and what caused it. Like the other week I crashed my t-rex 450 while doing circuits because I forgot to add more throttle when I turned into the wind and didn't pull up fast enough.

Anyways like AWW618 said it could be a bent shaft, but also check to make sure the bolts on your main blades aren't to tight so the blades can straighten themselves out during spool up.

Start at the basics, Look at the "everything" in the rotor head... Make sure the main shaft is true,if not start replacing! check your bearings,look at the feathering shaft, flybar etc... Then adress the blades, IF they are wood get rid of them, They are warped with age.... Get new ones, balance them and IF I know Raptors, It will spin true after you track it in....
Good luck and let us know how it all works out!
