My first trip to the field alone was great! I was nervous, but it all worked out perfectly. Second trip was not as successful. At some point right after takeoff on the second flight, I lost the crossbar screw that holds the carburetor on my Evo .46, and I lost throttle control. Engine kept running, but I couldnt throttle down to less than about 75 percent. What I "should" have done, was just fly around until I ran out of gas, and dead sticked it in. Instead, I decided to try for some tall grass across the fence from the airport I fly at. Being only the second time I had flown there, I mis-judged my altitude on approach, and clipped the fence as I crossed it. Destroyed the wing on my LT40, but everything else survived. A new wing and a few minor repairs later, I've been out 7 times since then, and everything is going great thus far (knock on balsa wood).
