its not fun losing planes because you were to cheap to spend a few bucks. I lost an avistar trainer on my first flight because I had older elastic bands. I put 10 on the wing and they seemed ok but 2 minutes into the flight they had all broken and the wing came off. My saving of buying a new 3 dollar box of bands cost me the front six inches of the fuselage. within 3 months though it was flying again after a rebuild but that was only after I got over how annoyed I was with myself for dumping it in the first place.
