Set fail safe to idle power
and range check with engine running

A turbine powered model is carrying an additional electronic control unit (E.C.U.), an electric fuel pump, battery and the associated wires and connectors. The radio antenna should be routed away from these components when possible and favor the top of the model for best receiver range.
Some controllers have a fail safe feature that will kill the power to the fuel pump should the signal be lost for a few seconds.
Set the transmitter "fail safe" program to cause the engine to return to idle and the landing gear to extend, set the flight controls to assume neutral in "hold" during a signal interruption.
Range check the radio installation with the engine "off" according to your radio manufactures instructions to establish the maximum distance before "drop out". Change antenna routing as required to maximize range and be certain that it meets the minimum as recommended by the instruction manual. Check this range with the engine at idle.
Range check again with the engine at full power as your assistant holds the model. Should the engine go to idle signaling a "drop out" at a significantly shorter range than before (engine off), indicates a problem. Reroute components and antenna until a satisfactory uninterrupted signal is obtained.
This failsafe set up will also give you an audible and visual warning in flight should a significant "drop out" occur.
BVM uses the JR10X radio with the 950S receiver. The minimum range that we accept is 60 paces with the Tx antenna off. If the antenna is on the right side of the model, we check the range from the left side at 90° to the fuselage axis. You would be looking at a side profile of the model. We have found that all of our turbine models perform well in the air if this range check criteria is met.
