The wildcat 30/23 contains only synth oil. With this high nitro level, I guess that the combustion temp. will be quite high. Maybe it should have contained some castor oil in case of accidentally extreme temps?? I am not sure but, with 30% nitro, the combustion and engine temp can get quite high and perhaps some castor oil as a saver would be recommended.... Just a thought....
Anyone with 30% nitro experience who can comment this??
The engine runs so cool on the 30% nitro that you can touch the muffler right after shut down and not get burned. The engine is just warm, not hot. The main needle is 3 to 3.5 turns open so you get a ton of fuel and oil though the engine to cool it. The low-end should be rich enough that when you hit throttle hold from a hover the engine goes to idle right away. If hesitates then the low end is too lean!
