Howdy.
I have recently bought a kitted out Aurora fitted with the OS61FR engine. It runs sweet now I have fitted the Positve Fuel Pressure System as you can see from my pictures. It has taken the guess work out with leaning for a whole flight and inverted flight is as good as the right way up. Best investment I ever made and now a devotee of the system. Nothing like having the same mixture setting at the end of the flight as at the beggining! Here is the web site:

The plane was fitted with the SCHIMITAR prop when I got it but definately looks the part. The engine turns at 10,230 RPM but usually lives at half throttle and is still fast. The OS#8 only seems to last about 10 flights. Wouldn't mind knowing if anyone has had success with any other plugs?
The plane has now completed 35 flights with me now but a total unknown about her full tally! Probably over 100 I would say and still a true flyer and looks like she is on rails!
