Simuliar to your PBF. Same equip. as you mini PBF. I test flew mine today with a rudder mod. that I added. Flat spins upright & inverted. Waterfalls, harriers, hovers, torque rolls. Its a ball, plus its got the CF rod protecting the nose like the UFO, but I like it better (IMO) Ck it out when you get a chance.
