Status: offline 		I am running an APC 17/6 on my YS120 @ about 8800-9000 RPM. When I had my YS140, I ran a 16/10 & 17/8. I don't remember the engine speed.

Status: offline 		Never had a 91. I would think that a 14/6 or 15/6 would give you a lot of vertical power

Status: offline 		You can use either our 2 & 4 Cycle 15% or the 20/20 fuel for your engines. The YS 20/20 will simply make a little more power. As for 30%, this is simply to high of nitro for the YS, yes it will run, but the engine will tend to overcompress causing detonation.
