The exact same airframe, or the same type airframe? Are both of your radio setups exactly the same (extension guage, y-harness, receiver type, battery type, etc.) or are there differences? The servos that failed were both rudder servos correct? Connected to the same type of gyro?
I want to get as much info as possible to give to the service department. The more factual info the better chance we have to figuring out what's going on.
