I purchased a Futaba 6EXA a couple of years ago and am now ready to upgrade to either a 7CAP or a 9CAP. I found a really good review on the 7CAP at http://www.rcuniverse.com/magazine/a...article_id=321. But I haven't been able to locate a similar review of the 9CAP. What I would REALLY like to find is a side-by-side comparison of the two! All I will need is the transmitter, since I already have several receivers, servos, etc. My local hobby shop can get me a 7CAP transmitter for $160 and a 9CAP for $280. Can anyone tell me what you get with the 9CAP for the additional $120 (besides 2 additional channels)? Thanks.
