My reasons for buying the 9C were:

1. My trainer came with a JR 431 computer radio and it only had two models.

2. The JR radio that I had didn’t have any exponential programming.

3. 3 years ago the 6XA and the 9C radio package were only $100 difference.

4. The 9C offered me more models, more programming options, granted I am still not sure that I need all of them.

5. The 9C has a frequency module that legally allows me to change my frequency. I believe that I can even use the ground 75 MHz frequency.

I have been in the hobby for 4 years.
I own:
( 2 ) Futaba 4 channel radios
( 2 ) Jr 5 channel radios
( 1 ) Futaba 9C

I still have the futaba 4 channels because I use one on a flight SIM., and I keep one in the van to buddy box with.
I still have the JR 5 channels because I still have the trainer planes that they came with. I also use theme as buddy boxes if needed.
I only fly the 9C! I believe that once you try it you will understand why nothing else compares.

My wife has taken a very large interest in the hobby and we are saving up to buy her a 9C as well.

Please understand that I have nothing bad to say about any brand of radio. I personally prefer Futaba transmitters.

I bought the 9C because other friends had the 9C. I enjoy its ease of use and it gives me more options than I will probably ever use.

A few amenities that I like about the 9C:

1. I like the timer option. I can make the timer start when throttle is applied. I can
make an alarm sound at a pre-set time to tell me when I need to land.

2. It allows me to use two separate servos on the wing and have them adjustable independently.

3. Throttle kill is a very big plus for safety and convenience.

4. I can assign rates to virtually any switch I want. I usually assign all servos to one of the triple switches. Insane throw, manufacture high rate, and manufacturer low rate.

5. Exponential allows me to fly planes more relaxed. It allows me to fly very touchy planes without being touchy.

It has made me a better pilot!

Sorry for the long report. I guess my coffee just kicked in!
