RE: Craziest thing you have done in this hobby
I spent hours and hours building my Extra 300 ARF, making sure EVERY preflight detail was exact. Throws, arms, linkage, trim, you name it. All I had left to do was do a final tuning. That went perfect with a new OS engine. Turned her off and politely proceeded to step on the damned tail and smash the crap out of it. DUH.
