Backpacker - that sounds interesting!
Your point about EASA issuing their own STC for Mogas has appeal. I run an O-360A4M in a 172. Previously, if I wanted Mogas I had to pay a Mr. Petersen in USA for an STC. Where would I find the EASA version, what cost, and do I need any mods?
Sorry to ask so much! Regards, CT.
