The rules go by times. Gold silver and bronze class. I just came across a Super tigre s75 with a tuned pipe. Also got a new ring and cylinder sleeve. I plan to increase compression and maybe open up the ports a bit. Also going to get a slightly bigger carb. Does anybody know what carb may be slightly larger? Any way it should be a cheap screamer for this 6 lb plane. I think the 115 would be over kill lol. Ive heard these st75 engines pull 10lb plus planes around so my power to weight should be plenty. I also have the same plane with a saito 91 and it rips.
