Model engines have relatively low compression ratios.
Hi,
I just wanted to comment on the fact that some model aircraft engines will work better on high octane fuel. When I run Zenoah it seems like there is no problem using the norwegian standard 95 octane unleaded, however 3w seems to work much better at a higher octane. At least 98 unleaded (highest we get in a pump) or even better aspen 99 octane evironmental friendly fuel design for small 2 stroke motors like chain saws, go-carts etc.
Therefore I'd like to try the 3w's on avgas.
