OMP 65 Yak ARF. It will do everything 3D. Hover and torqur roll effortlessly. Flat spins lose no altitude. ZERO coupling in knife edge at any angle/speed. Mine is the kit and weighs just under 7 lbs with the YS 110. I may still order the ARF as a backup. I like it that much. Do a search on here and see what others have to say about this plane.
