I was told strictly IMAA at the main and 3D flight lines. You CAN fly them at the electric area, though.

Vroom. Not my best flight today but the one that got videoed
Thanks buddy. They will. Its all about the setup i think, and forward speed. After Ben spent a little time with me on my red one in texas, harrier started getting mucho betta.
These guys in my humble opinion, like to fly with a lil nose forward cg. Once this spot is found, all moves tend to get gooder
