1. Never ever switch a Servo Dip Switch while the model is active with the battery connected and the electronics active with the transmitter turned on! Always perform such an operation while the both transmitter is turned off and model's battery is disconnected and electronics switch is off.
2. Never mess around with the first dip switch since this is your throttle!
3. Never try to repair a previously damaged Li-POLY! Great risks involved during the repair since an unknown exists as to the extend of the damage and home and/or car plus humans could have resulted. This person is very lucky this battery melt down happen at the field!
