I've used the 9303 for over a year and have had it in 4 jets and many prop planes. It will work fine for most jets but some of the more complex planes will be a little bit of stretch requiring Matchboxes, Equalizers, Xpanders, etc. to get there from here. I find I've maxed it out most of the time, using all the mixers, all the channels and most or all the functions possible to use at one time. There are many pluses and many minuses. I don't think it's the awesome, end all radio JR would have you believe, but then again, it's my primary jet radio, and, all in all, I like it. Just don't try to use the Button for anything but the Timer (if you have it active). I don't know how many times I've been out of gas/deadstick until I realized the Button was turning my timer off and on when using it for smoke.

It's way lighter than the 10X and more comfortable for me personally. It has most of the features and mixers but lacks the 10th channel. It looks like they took the 10X software, made some improvements and other changes, improved the menus, stripped out a bunch of things, and mucked a bit with switch assignability (though still lacking dearly in my opinion). I think the menu is easier to navigate and I like the rotary encoder, but I hate turning the radio off and on to get to Device Select & Wing Type menus.

First thing to do is throw the Tx battery away (600 mah) and replace it with something having decent capacity. I put a 2500 mah Nimh in mine. Good now for a whole weekend of hard flying.

As rcjet said, it will work for a lot of planes.
