I have flown Suitcase's Extreme Flight Yak and his Ultra RC Edge 540. We land both without the gear with no problem. Check out the 3dBuddy from Ulrta RC for $174.95. It comes with brushless motor,speed controller and gearbox. I have also been using a 5 channel Berg reciever in my Tantrum 3D with good results and Hitec 55 servo's.
