As a general rule I would agree that there are not many electric combats that can reach the speeds. However, for anyone who is interested, my XE Combat Wing was clocked with a police radar gun at 84mph. Not quite 90, but damn close enough for me.
My wing bounces off everything and just keeps flying like nothing happened. Plus it will out maneuver any of my gas planes, and when you want to land you can just catch it or let the dog chase it and bring it back. Good clean fun. The joy of 100% EPP foam.
