Have two categories of "first crash" - RC Sailplanes and RC Powered. I flew RC sailplanes happily for a couple of years, causing more damage getting them to and from the flying field than flying. My first sailplane crash was with a Soarcraft Libelle, a state of the art kit in the late '70s... Had spend a LOT of time building it and finishing it, and was extremely proud of it. Simultaneously, I built my own hi-start with a length of surgical tubing and nylon cord. Went to the park where we flew, and staked down the hi-start, took the slack out of it and handed it to a friend while I got the radio on and checked the glider. Everything was fine, so told my buddy Steve to stretch the hi-start 20 paces, where I'd hook up the glider and launch. As he was walking back, Steve said "You know, this is feeling pretty tight", but I discounted his input because he had never pulled a hi-start, and 20 paces was a normal short pull. I hooked on the glider and launched it. Well, it was a glider for only for the first three or four seconds, whereupon it became two wings and a fuselage flying in not-too-close formation - the wings fluttered uselslessy to the ground while the fuelage followed a 150 yard ballistic trajectory, bouncing for another 20 yards for a total flight of 170 yards. Seems the rubber I bought for the hi-start was about 1/32 thicker in wall thickness than the rubber I had used before.... Steve was right.... For my first powered crash, a full size flight student of mine who worked at the LHS and was a highly experienced RC pilot, convinced me to try a powered airplane. I agreed, with the condition he select an appropriate airplane and help me learn to fly it. Tim chose a .19 powered first generation "Pilot" Japanese foam with shelf covering ARF. After a week's work, had the airplane ready. Took it to the local field, and Tim took the airplane up, flew it, tweaked it, flew it again and pronounced it airworthy... Experiencing more anxiety than I had expected, I taxied the airplane out and advanced the throttle for takeoff and lifted off rather smoothly, IMHO To get the feel of the airplane, I took it out a ways and bumbled around till I thought I could control it, and returned for a low pass traffic pattern. I entered a right downwind, turned base and maneuvered the airplane successfully (if not too smoothly) onto final when I caught sight of another airplane out of the corner of my eye flying the opposite direction FAST. Unfortunately, my full size airplane instincts took over and without thinking, I rolled right and pulled back, avoiding the oncoming traffic and completing the prettiest half split-S you ever saw, terminating nearly vertical at ground level... Needless to say there was little remaining of the mostly foam airplane... I was more than a little ticked, mostly at my gross newby overreaction, when Tim came over, put his hand on my shoulder and asked "Should I get the Hobby Rake or do you just want to leave it buried?"
