hi there.
yesterday I went flying with my Great Planes Pitts Special 1/3 (the ZDZ is on its nose) and after 11 minutes of flying the engine flamed out at 50% of throttle stick position...fortunately the damage caused by the forced landing is not as big as expected...
any ideas on this out of cause flameout?
the tank was 50%full, the ignition pack voltage was ok and the fuel was 40:1 unleaded gas and synth oil (after an email to the zdz distributor I was assured that there is no problem to use unleaded gas )...[][][][][]
