All you have to do is look for a is an RX that has at least the number of channels that you want to use and is a 2.4gig, FASST compatible receiver.
any channels beyond what your TX puts out signals for just ignore. Plane or surface makes no difference in 2.4 Gig. You might look at the antenna
arrangement, I know that some of my surface RXes for my FHSS radios have internal antennas to make them more convenient to set up in a car
or boat. I have had good results with some of the HK compatible receivers. You might also check out Motion RC, I think they might have some
compatible RXes.
