Im a little confused about what % fuel the ofna hyper 7 uses. Towerhobbies says 10-15% and then ofna web site says 20%. Which one is it?

i wouldnt trust tower hobbies, they may have messed up, nut the official ofna site i would trust. basically, 10-15% nitros are not very common, my lhs doesnt even carry it much. it usually doesnt matter what % of gas u use, i take whatever is available for my .18 associated mgt and my .28 ofna ultra. 10-15% are going to not run as high rpm's, 20% is the average, and 30-33% run very high rpm's. i would take the 20% if i were you, it has a perfect balance and not overkill especially if its a new engine.

I agree....go with 20%, however the "racer's" usually go with 30%.

By the way, there is a "buggy" forum. In case you have more questions, there may be experts lurking there..............
