BuddyRC is the place to get your OMP Hobby parts and helis. I have a M2 Evo and they have all of the rebuild parts I need when I crash. Which I do a lot cuz I'm new. But getting there.
Shipping is really fast - if you order from OMP in China it takes a month. And the prices are really good - stuff comes within a few days.
Win win win all around!
OMP and BRC in general are really top notch.
