I had a little flame problem this past weekend...
Flames were orange/transparent (Hard to see)

The ECU measured the last temp as 1045 degree centigrade (Well over 2000 Fahrenheit) when the normal full power operating temp should read no more than 600 F

This was not caused at engine startup by the way. this was after about 2 minutes into the flight. Looking at the Elevator and rudder servo leads I think I'm lucky to get it back in one piece (So to speak)
