RE: First re-kit
I feel your pain.
I bought a cool looking, finished plane from a flying buddy, spent a bunch of time setting it up to fly. I even bought a carb for an engine that I had, but was set up for control line. First flight: it just did NOT want to turn. I tried hard to bring it in safely. It came in with a THUD! I hate it when THAT happens. [:'(]
I hope you are able to either fix it or rebuild it with the knowledge you have learned.
