RE: Evolution 1.00 vs OS 91 FX
oh, I don't know, usually you have to be a bit lucky as well. I fly Saito and OS-MAX, but that's basicly because they are good brand engines, and the local hobbyshops carry the parts if you need them. I don't buy any of the cheaper brands, but that's because I don't have time to fool around, the time I have available I'd like to use flying. There is nothing worse then spending an afternoon trying to get an engine running, cursing yourself why you did not spend the extra 20$ on a "good" engine (even when that has nothing to do with it....). My OS-91FX now runs 9800 rpm with an APC 14-8 on 5% nitro, and I am very happy with its performance on a 7lbs airplane. I found the idle setting too rich, but I did not mind this when running in. The engine now runs very sweet, so things went well I suppose.
