Hi guys. I have a Futaba 6eax 2.4 and 3 receivers, 2 606 and 1 617 and I was wondering would the Futaba 10c "which I plan on buying" be compatible with these receivers . Also I like the 6eax but one thing that annoys me is that they never put a timer on the radio which would be very handy. Thanks in advance.

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.

"If all you feel you are missing is a timer though... that is an awful expensive timer."

Yes, but you get three timers on the 10c

You can use the 606, 607, and 617 receivers with no problem.

As you can see here, the 10C will work with any Futaba 2.4 RX from the 606 and above.
