I have to agree with those who want more power than the OS 160. I have the H9 Edge w/OS 160 combo and the power is not as impressive as I'd planned on. I have very limited time on it, and the engine isn't broke in yet. 3 flights in a row with dead stick landings and I'll tell you what, that thing will glide forever! I think it depends on the kit and how careful you are putting it together. I got very lucky and also paid extreme close attention to all construction steps, but I can't see any bad habits so far, glide and stalls are amazing! This plane is very capable and I can't wait to get more time on it so I can truely brag it up. Some bad experiences out there with this plane have put a bad taste in the air, but there's more to it than some may know. The wing thing didn't help its reputation any, that's for sure. I know a couple people who were well beyond ticked off when they lost theirs due to wing failure. Other than the one piece wing, I sure love mine so far.
