I had another question, will you be running in the engine on glow?
Would be interesting to see what numbers you get. The old ones would do about 16500 rpms ( 10% nitro) on 6x3 props and from what I've heard the news ones are not any better...
I really like the way this engine runs though, it draws attention at the field and people at the field ask about the size and seem surpriced by the performance, it really runs like a much larger engine with easy hand starts and reliable idle etc. If only they had made a pro BB version also...
