I had an Aeroworks profile with the BME 50. The BME 50 is and outstanding engine that has unlimted verticle with 16lb planes and is extremely reliable.

Two problems, its very hard to get sufficient space between the engine ignition components and the radio gear. If you haven't ordered your BME yet then make sure to order the Bosch cap with it.

Second, when the BME was idleing the profile fusalage looked like it was made of rubber. It really shook, it moved at least 3/4 inch rotationally as the engine idled.

I lost the plane on the 4th or 5th flight due to radio interferance. I know many people blame thier crashes on this but the plane flew over head and as it got 45 degrees off my right shoulder it went into a slow rolling dive. I had plenty of time to work the sticks. I pulled back on the throttle and held the transmitter high over my head but nothing made any differance as it slowly dove into the trees.
