bigtim, the Conquest is an older four channel system. I'm looking at costs of receivers for when the plane is equipped with floats just in case the receiver gets soaked beyond repair. The receiver that would work with the 9C is around $100 while the receiver for the Conquest is around $40.
Isn't the 9C capable of transmitting both PCM and PPM? If so, you can use a lower priced receiver for the float plane. Also, you of all people should know how to build a waterproof radio box to protect the electronics!
