So far, I have the XG 11 installed in the PAU300 using the RG1131B rx. I've got 9 flights on the PAU now and I really like how it performs. I plan to move it to my more expensive planes as time goes on. Especially the Sukhoi, the 260 and the Hempel. It feels really comfortable in my hands, the sticks are ultra silky smooth and once you get acquainted with the menu, it is actually pretty easy to navigate. I really like the styling of the radio also. Still not real clear on a few settings but I am sure I will figure them out. As for the 9X, the really gratifying features are the menu is exceptionally easy to navigate and understand. My 8 year old grandson could program the Hitec. It also feels really good in my hands. The sticks don't have the "feel" that the JR has, but still very smooth and very precise. Two things I like on the Hitec over the JR is the sliders on the back of the radio. The 9X just really fits well and are very accessible. The JR are a little "odd" feeling. To me that is. The other thing is the price of the rx's. Ultra inexpensive. 69 bucks for a 9 channel Optima 9. While the JR is nearly twice that price with only two more channels. The 9X is a very hungry radio though. With the two processors onboard, it eats a 2000 mah lipo in about 2 hours. A 2600 Li-Ion in about 2.5. The 1300 mah Nimh that is supplied with the radio won't last an hour and a half. The XG 11 is supplied with a 6.4 Life 1400 mah 2s battery. It holds for a solid 3 hours before I see a noticeable drop in volts. Both radios have great telemetry packages. Overall, both radios have the same useable features with the JR having only a slight advantage of some mixes. But nothing I care about. Both have programming features that are well beyond most peoples expectations. Dollar for dollar, they are both awesome radios. I was going to off my Hitec when I got my JR, but I figure it is more cost effective to phase out the Hitec slowly. I am most definitely not a radio wizard but from my own experience with both radios, this is what I have found.
