Hey Vic Vic,

I personally have the following balsa 3d's. Buddy edge, original buddy, extreme flight yak, Cermark Banchee, Hobby Lobby Extra 330, Raidentech firebat, and others not worth typing. I've been flying for 20 plus years. I started flying profiles back in the early 90's when no-one cared about them. As far as my experience the original is the best flying plane I have.
I'm running the Himax 4200 gearbox with the 4.4.1 gearset. Kokam 1250 15c cells 3sp1. Hitec Optic computor radio Hs-55 servos and Hitec 5 channel recievers. The Himax 2812-850 also works well. apc 10-4.7 on the 2812 and apc 11-4.7 on the gearbox. Let me give you some advice. Make sure the plane parts are straight. I hot glued it together. I found the screw together method made it warped. I maxed out all throws without binding and run elevator-flap mixing on always. Use expo
say 50% on ailerons, some on the elevator and rudder. I've been flying extreme for awhile so I would tune it down at first.
What's really weird all my buddys, yak, required alot of right trim. It was balanced laterley. I fly the tail heavy and I can go upright to inverted flatspins back and forth, and with the Himax 4200 it will climb flatspinning at 1/2 throttle. I've been waiting for the Katana Buddy to ship. I'd buy them all. Hope this helps any other questions just ask. Oh, if you order the package deal which is good, order a spare gearbox and make sure the motor screws are tight, loctite (Blue)
