Well I found out how to build the interface for the XP-662 for FMS but I still would like to know if it is ok for a helicopter. The auction says it is but Randy seem's to think it is not.

The model is JR XP-662 and the auction describes it as: 6 Chanel Airplane Computer Radio

So I dont know if that means it is for a plane only or is ok for Heli's also!

Thanks,
Kevin
