Hey guys, I just ordered a Futaba 3PMX radio, and the included receiver is a R603FF. However, I also just bought a surface pack, which includes the R603FS Receiver. I intend to get rid of one of the receivers, will the 603FS even work with this radio? Or should I just stick to the one with the radio? If both will work, which would you get rid of?

The 603FF has a fail safe that the FF lacks. If you can use both, I'd keep the FS. I looked on Futaba's site and there is nothing I can find that says one way or teh other if teh FS will work with your tx. You may have to email them to find out or just bench test it.
