The hottest plug you can get will help in the cold temperatures too. Was out flying yesterday at 3 below F. Higher nitro helps too. I run 25 %.
First, how can you stand to fly in -3? [X(]Second, How do you keep this engine from going "boom" with the 25%?Do you need head shims? If i did that, I would have a face full of engine( I would be out in the field "look, I found the piece of crankcase that says OS on it!"
