I used this plane for the Unlimited Class at the Midwest Slope Challenge and was very impressed with how fast it was in the light conditions. Several people commented on how quickly it accelerated when the nose was pushed down. In fact the acceleration helped me win one of the heats as we both dove for the finish line.
The durability of the plane was also tested in a race where the wind had come up allowing some good height to be gained before the start and as my competition and I dove for the starting line, holding until the last possible second to pull through the line, when I was about 2 feet off the deck, he bounced off the top of my Prodij slamming me into the ground. I am not sure how fast we were going, but it was fast for sure. Several people thought the plane must have been destroyed. As it turns out just a small hole was punched in the nose cone.
