The receivers will be compatable with the 10C. If all you feel you are missing is a timer though... that is an awful expensive timer. I have been flying a 6eax for about 3 years now (72 Mghz) and decided I needed at least 7 channels for dual elevator servos without a reversing Y-harness. I ended up going with the JR 9309 2.4 Ghz as I was not happy with the computer interface of Futaba. Since you already have 2.4 Ghz receivers for Futaba the 10C may be your best choice.
