I received this FlatOut RCU Biplane from my lovely sister-in-law at Christmas. This was the maiden flight. It's a great little plane. Now that I've got the CG tweaked, she flies awesome. It's easy to hover, and do all other kinds of 3D flight. Nice and slow. It's all stock setup. I get about 9 minutes on a 20C 600mAh 3S LiPo. She hovers at 1/3 throttle.
