I also just bought the Reactor Bipe but I'm going crazy looking for a motor for it. I have never tried the motors they recomend so I'm a bit hesitant on the Rimfire. I have never heard anything about them ( good or bad ). I have been looking into the Axi 2814/16 this is a very cole motor to the Rimfire specs or the 2820/12 but weighs 5.3 oz but will pull a 53oz 3D plane. My biggest concern is that I don't want a motor that will barely fly this 3D plane, I want more power than I need, but still want a light plane I can float by...........Some one help me PLEASE!!!
