RE: Why Can't I Crash???
Get yourself a profile (preferably a Mojo because they're *really* tough and fly great).
Fly it like you stole it.
Even though it's a cheap/tough plane you will still be scared of crashing.
Keep telling yourself "the closer I fly to the ground, the less distance my plane will fall if I stuff-up".
Practice hovering on the deck -- keep down below 1-3 feet and practice tail-touches. This will almost guarantee that you will have the occasional "unintended encounter with the ground" but the Mojo will laugh it off.
Once you've "blooded" your plane (ie: incurred at least some minor structural damage) you'll feel much happier about throwing it around and "hucking low".
Then just get out there and set yourself some goals.
"Today I will practice rolls (or rolling harriers) at no more than 10 feet above the deck"
"Today I will practice blenders with pull-outs no more than 20 feet above the deck"
etc, etc.
I have a bunch of profiles (and a 50cc Extra 330L) but make sure I always have at least one old beater profile that I can use to *really* push the envelope. My current one (a Katana P) is now 60% repairs and 40% original. It has carbon roving and cloth all over it and has covering film peeling off it in several places. But this plane owes me *nothing* and if I totalled it tomorrow I wouldn't shed a tear -- I'd just demote one of my other profiles to the role and buy/build a new one.
Remember -- a profile is only worth $100 or so. Once you've had your $100 worth of fun flying "safe", it owes you nothing and you might as well enjoy the "bonus time" by really pushing the limits.
