Really enjoying this thread. The pictures are SUPERB! Especially the combat pic with one of you inverted, as well as the balloon bust pic!

Your experience jogged a memory file...
In the late summer/early fall of 1970, toward the end of the flying day. You know, that wonderful time of the day I call "The Witching Hour" where it cools off, the wind dies down, and everyone scrambles to put in their last flight of the day. Anyway, one of the last flights was being flown by a youngster by the name of David Jamel (very good flyer). He was putting a 36X powered Voodoo through its paces, tearing up the air. (God I love the sound of a vintage combat engine on a vintage combat plane tearing up the air!)
As he did so, suddenly there was an ever-so-slight hitch in the RPM of the X engine, and then it suddenly revved up to a zillion RPM. A part fluttered to the ground. (A prop blade?) With the engine sounding like a high pitched screamin' demon, the Voodoo glided in quickly for a landing... castor smoke boiled around the grounded plane as it continued to scream. (It MUST have been hitting near 30,000 RPM, given the pitch tone of the exhaust note.)
Dave's dad, Joe, ran to the model and grabbed it up to stab its nose in the ground to stop the run-away revving. Well, that only works of there's still a prop hub! Trouble was, the prop shaft had broken off! So, he began to hurriedly open the needle valve until it finally stopped screamin' its guts out. As I recall, the engine was no worse for the experience, and once the crank was replaced, flew many times afterwards.
Amazing the things that can happen in a C/L circle!!
