For plane number three I would recommend the Hanger 9 Ultra Stick 60 size with a Saito 100 4 stroke engine. You'll love this set up. Not the best 3D plane by any means but pretty tough and super easy to fly. A good pilot can hover this plane and it will do nice rolling circles and many aerobatics. These are great planes. I still fly my 120 size quite a bit and I'm on about plane number 25. The 60 size is big enough to handle a bit of wind and with the Saito 100 it will be spirited enough to keep your interest for a good while.

Thanks
