Second Plane.................I agree with most of the guys. A bipe as a second plane is quite a handful. My second plane a shoulder wing GP Easy Sport 40. This plane is quite responsive advancing you for aerobatics. You can fly it wild or tamed. With an Fx 46 this plane flies great, easy take off and easy landings. I built mine as a trike. My third plane is a Funtana, still in the process of building it. But I'm not at the 3D stage, but still flies docile as I've seen others. I'm now building the Pica Waco YMF - 3, 1/6th. scale, by the time I'm finished building this baby I should be ready to fly it, still that's going to take to the fall. So actually a bipe is going to be my fourth plane. It takes a lot of time to build a bipe, and also money. Bipes are wonderful but......rudder, rudder, and has to land with power, it's not a trainer or to the novice flyer. Then again it's only a matter of opionion and skill.
Good luck.
