Good Story!

Fix #1 - After you land the model, adjust clevises so trims on the tx are centered. Then you'll never be far from trim if you put the trims in the center in case you move them. Also makes it easy if you use the same tx for more than one plane.

Fix #2 - Don't land in trees.

Fix #3 - File a flat on the axle and use non-hardening Loctite on the wheel collar set screw. Wheel collars fall off all the time. In fact, I prefer to solder a washer on. It looks nicer, is lighter and is more secure.

Great job considering your low number of hours! [8D]
