Status: offline 		I have a homebuilt "test-bed" I use for testing conversion motors out of weed eaters, chainsaws, etc. Its 120 size "Stick" design I bought off a fellow clubmember for a mere $80. It's kinda ugly, but who cares?!?! I mounted a 32cc chainsaw engine to it, and after weeks of engineering, she actually got airborne, and flew flawlessly...Now, theres about 1 hour of flight time on the thing,(which is quite a bit actually), I took it out to the field after the football game Sunday (Falcons suck), and was fully intent on impressing all the "Oh it'll never work", and "It wont have enough power" skeptics that were there. Again, the thing lifted off of our 400 foot grass strip, and zipped through several rolls, loops, etc, and after about 8 laps, the little engine made a strange sound, and then simply separated from the firewall....It held on to the throttle linkage for about 2 seconds, which placed it in a full throttle configuration, and proceeded to try to "saw" my over-engineered landing gear up with the 18x10 wooden prop. Now my CG is about 3 inches forward of the vertical stab, and I'm trying to just fly the damn thing. In the background, everyone is yelling "keep the nose up", "you need more airspeed", and I'm thinking "No ----, I also need an engine!!!" Im at about 60 feet, no engine, and full elevator "down", the nose is at about a 2 degree nose down attitude, and the airspeed is about 6 mph. The airplane actually "auto-rotated" (the only way to describe) flat into the rough grass, causing only minor damage. The hardest part was flying this 17 pound "glider" to the ground while laughing un-controllably, along with the rest of the guys watching. We had a BLAST with this thing. I highly suggest this type of flying, as it is cheap (gas is $1.89 per gallon here in the ATL) and loads of fun.... Gear epoxied back in, engine parts salvaged and placed onto spare (I had 2) and almost ready to go again....
