Could I suggest that you get a LITTLE help/advise from an instructor even if you don't feel like joining a club?
Try calling:
SCOTTSDALE MODEL FLYERS
DAVID CONRAD
10717 N 103RD WAY
SCOTTSDALE AZ 85260
Phone: 480-451-3280
I'd bet he'd be willing to give you some help/advise and maybe find out some of your problems in a cheaper manner. A call is cheap and easy.
Depending on WHY you crashed, another flat bottom wing may be in order and the Tower 40 ARF is quite inexpensive for you to just move your gear over into.
You said that you had "some success" but that is difficult to interpret.
