RE: How many times do you crash?
I have several models I have never crashed (I had to go and say that and so jinx them now . . . ). BUT, I have crashed my 3-D stik model twice this year. Both cases the landing gear tore away and in one "pancake" three of the four aileron servos lost gear teeth. At least I hit the ground upright, but if you have to get out the Titebond II or epoxy - that's a crash. I would say I fly a bit wilder and try zanier stunts (or just maneuvers closer to the ground) with my designated 3-D/sport model. Not disposable, just purposely owned to be flown harder.
Had a couple years where there have been no crashes or even hard landings. On the whole I'd have to say I crash at least once annually.
