Status: offline 		Looking into getting a new motor. Anyone have experience with these? Preferences/recommendations-all i know is the recommend gear ratios and needed mods, what about the practical application side? Thanks

Status: offline 		I have both. The OS91 makes more raw power but is a little more finicky to set up and run. The YS 80 is a bolt in and go, good power and the same YS reliability we got from the 61s. Use a gear ratio around 7.8-8.2 for the 91 and 8.2-8.5 for the YS. They will work on other ratios but after testing I think these are the best, though others think differently.
