In my humble opinion, the Tuff Trainer is a very good plane to learn on. It's a front engine plane, but is made from EPP, which tears instead of squashing/disintegrating, making it very easy to fix. The motor is also very good and it comes with a prop saver. My Tuff has bounced back from hitting trees, the ground and even a metal light post! Being a high wing craft with plenty of dihedral, it floats and self corrects nicely. Although it has ailerons, they don't do a hell of a lot, but aerobatics wise you can do loops and (not very tight) rolls. The wing loading is very light (lots of wing area for a lightweight plane) so you can load it up with gear like night lights, cameras, streamers etc. The prop that comes with it doesn't get the best from the motor, and with the prop saver it'd likely last forever, so change that to a 8x3.8 slow fly prop and you've got a winner!
I like the Bixler, and it has good flight characteristics for beginners, but EPO foam does warp relatively easily. Also the elevator does too much, which is not a good channel for lively behaviour for a beginner! I've also seen the little cutout foam pieces around the spar come loose in midair after being firmly glued with epoxy...
In terms of your radio, can't recommend the 9x enough. You won't grow out of it in a hurry. There are better radios, but they're three times the price. Order one of the mode 2s that's on backorder on HK atm, as it's only 39.99. I doubt they'll be that cheap when they come back in stock. If you prefer mode 1, it's a very simple job to switch the sticks.
