Does the Zero turn the same RPM on the same prop as the standard 185cdi? I am looking at this engine for a scale project, but I have been running YS engines since the 90s in pattern planes as well as scale. I have not been able to find a direct comparison anywhere on the web yet. Using 30% does not bother me, but using zero would be nice since I can buy methanol locally and mix with cool power oil that I have 2 gallons of.
