Me and a couple of buddys use the GWS Mustangs. We just tape a 15 ft streamer to the back and have at it. To make it fair, we all use the stock 350 motor "C" gear with 9x7 props and 2S LiPoly. You can't just pick them up and throw them again after a crash, but it is foam and it will epoxy right back togather again. If you do trash it, you can get another slope glider version for around $30. Its a fun and cheap.
