The Osmose is finished and would have taken to the sky at the weekend but for our British weather. I have put 3 tanks through the OS FS82a and I already have a lot of faith in this engine. A 5 second prime on full throttle, back to idle and only had to touch it with the starter to fire in to life for it's first run. On very rich setting with a little leaning out from time to time and then back to rich I had 13 mins so fuel economy looks fairly good.[8D] Next weekend the forecast is better so fingers crossed.
