Build it as light as you can and you may have to put a pump on it or regulater. 18*6 Pro Zinger and Chip commented about running 30% heli in his 1.6 but I think that is what you would want to break it in with. CHeck his video out on his site and it has the 1.6 in it. As a matter of fact if you e-mail him he should be able to give you his set up. Good luck
