If two modellers switch on transmitters on the same channel the result is interference to one or both models and the usual result is at least one wrecked model Before you switch on the receiver ensure that the thrott le stick is at the stop idle end point Always switch on the transmitter first and only then the receiver Always switch off the receiver first and only then the transmitter If you do not keep to this sequence i e if the receiver is at any time switched on when its transmitter is switched off then the receiver is wide open to signals from other transmitters and any interference and may respond The model could then carry out uncontrolled movements which could easily result in personal injury or damage to property The servos may run to their end stops and damage the gearbox linkage control surface etc Please take particular care if your model is fitted with a mechanical gyro Before you switch your receiver off disconnect the power supply to ensure that the motor cannot run up to high speed accidentally The gyro can generate such a high voltage as it runs down that the receiver picks up apparently valid throttle com mands and the motor could respond by unexpectedly bursting into life Range checking Before every session check that the system works properly in every respect and has adequate range This means checking that all the control surfaces respond correctly and in the appropriate directio
