Thanks guys for the prompt response. Yes, the engine smokes a lot at idle and at WOT, at least on the ground. I don´t dare go full throttle while flying. This engine has too much power for this airframe.

I presume I have room for improvement by working with the needles, so I´ll do that next time on the field.

About the 15% nitro content, is that a must? cause it is so expensive and Bax said you could get by with 0%.
