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