I got a raptor 50 not too long ago, and I'm in the prosses of rebuilding it, I'm new to large scale helis and nitro as well.

If anybody can give me a few tips, and things to be concerned about, I would appreciate it.

Here are photos of the raptor 50 before I dissembled it.

One more thing, how can I know if I have a titan, my blades measured 640mm, but I don't know if the tail boom is a titan model.
