Yo, got to say I love it, only had a few runs on it so far. It goes into (and out) of places my other wing wouldn't get to. It's so playful, works lovely on the small hills, is really fast for a 13m and handles nicely. However not as nice as a small speedwing to launch in zero wind and needs a 500m landing strip to get her down, lol. Would like to try the line speedwing version, reckon it would be nuts. However do I prefer it over the 8m RX3??? .... No. Do I prefer it over the 11m R3? ...Probably, seems like it is just as fast but more playful. The RX3 is amazing, but the mustach is better for much more time in the air on the little hills. 🤙
