RE: nitro fuels
Since returning to the sport this spring, I started using Power Master 15% with 18% oil, and have been very happy with it. I run the same fuel in a ST G51, OS70 and an YS110, all seem to run fine on it. I guess its like car owners, your going to find some for every product for a different reason. Until I've been informed as to why I shouldn't use the Power Master, I'll continue to use it ....... Greg
ps: Marvel Mystery oil after run oil is standard also
