I had a BGX in a Yellow zero a few years ago. It handled the plane well. It took off in about 150' - 200' would loop from level flight and would maintain a sustained climb angle of 30 to 40 degrees. It was a good flying model until one day it rolled onto its back right after take off and made a Kamikaze dive into the road leading to the flying field. I never could find the reason for the incident as all of the radio gear worked properly after the crash. Maybe it thought the road was an American carrier deck.
