It is compatible with some Futaba and JR aircraft and helicopter transmitters with modifications. Futaba air transmitters require the positive and negative leads to be swapped because KO radios use reverse polarity compared to Futaba radios. For some JR air transmitters using the small white battery connector, the ProTek RC transmitter adapter PTK-5221 can be used; polarity reversal is also required.\u003c\/p\u003e\u003ch3\u003eInstallation and Charging\u003c\/h3\u003e\u003cp\u003eUse suitable foam to pad the battery in the transmitter compartment and prevent movement.
