Parts aren't usually a problem in the case of a minor crash. Usually the plane will pop open at the seams or split in other places. As long as you gather all the pieces that might have broken off you can uually just reglue everything back togerther. Then you recover the damaged areas with monocoat, check the throws and your set. Spinners or props that may get broken are common items at the RC hoby store. I have repaired planes that have been broken in 2 in about 2 hours. Engines are usually pretty tough and don't require any parts due to a crash. Of course it helps if you build a kit trainer instead of an ARf because then you learn how it goes together. This makes repairs less intimidating to attempt and is the reason why I suggest a kit for a first plane. Problem now is that we are running our of Winter which is the buiulding season and getting into spring.
