Even though you have limited time you would be better off in the long run by spending that flying time with an instructor. The ones that I have dealt with were willing to help me and would schedule a training session that fit into both of our schedules.

There are very few new pilots who are successful at teaching themselves how to fly. Besides learning to fly, an instructor may possess knowledge and experience with other things like motors, radios, sims, etc.

Think of it this way, the time you spend in repairing the crash damage could be spent flying. The money you spend for replacement parts, new airplane, etc could be spent at the local pub with your instructor as you discuss how well you are progressing in learning to fly...

Good luck!
