I have an AirHobbies 3 inch twin that I have flown for around 2 years. I think you may have never run yours. I found the engine to be a wimp for power and wished I had spent my money on known equipment instead of this heavy under performing monster. There are several problems I experienced. The supplied electronics fail, as did the warranty replacement. Once I had a replacement package overnighted to me at my cost because they were not going to warranty the second failure. When the second replacement failed, I converted to C&H and never had another problem. The muffler connections leak, the supplied shock mounts did not work well in my application (they caused other things to break as the engine bounces around at idle), the muffler/mount tends to allow the engine to rotate unless you are very careful in tightening down the mount bolts.

Unless you find an airframe that has built in lift, I very seriously doubt that this engine is capable of providing you with 3D capabilities, red paint that turns as it gets heated, or not.
