Chris, 

Yes, that was me that brought and demonstrated the IR fire detector.  I had it mounted in a metal project box on the hot side of my engine, but it failed shortly thereafter.  My guess is the UVtron photo tube failed.  Replacement sensors were $28/ea at the time, so it has been sitting on the shelf waiting for some time to mess with it again.  

Since I experimented with the first one, the design has been upgraded and the old model is no longer available.  You can purchase the whole kit for $89 at  http://www.acroname.com/robotics/parts/R345-UVTRON-PKG.html .  Just mount it in a robust box with a hole facing the engine and wire it to 12 - 24 volts.  You'll want to put an LED on the panel to warn you in case of fire.

Several years ago at the rotary get together in Pecan Gove south of Ft Worth, Texas a flame detector was demonstrated. Does anyone remember this and have any info on it?  The demo was impressive and I would hope/think the technology has improved and is available.

With the recent fire in a turbo rosary canard a few days ago it got me comptemplating such matters again. Especially in a pusher.

Thanks.
