Toller Motor, habe den gleichen. Ich bin erstaunt wie wenig Öl und Nitro Du verwendest. Der Hersteller gibt 20% Nitro und 20% Öl an. Welche Zündung von Rxcel hast Du?
A bit old but.... When I switch all my engine from Motul to Modellisport sfreda oil, I've set 0% nitro on a very high quality méthanol and 6% to 8% oil. Engine runs smoother and absolute no wear mark appear before a lot of liter passed. The oldest 40 2stroke run more than 600 flight with 500cc tank and stay the smoothest, start from one finger backward and rebound on compression to start. Bearing changed from stock to good one and ceramic test but not kept as solution due to price Yamada engine love 5% nitro but not absolute need Hope this helped. Oil % depend essentially of quality component over quantity. Motul let slight mark in sleeve and piston, dirt in bearing and burn easily in spring temp high use, I've made flight without cooling for hour with photo work or school flight, land ,refuel take off and after 2hours running good synthetic oil, engine stay acceptable temp. Motul don't let you do it for more than 40min and if not excellent OS engine, no doubt you block it in flight. I've still lot of this oil, but don't know which other choose if needed today. Good flight all 👍
