REFLECTOR:Secondary fire detection

[Ronnie Brown]

Neat.  I see they are "bomb proof" but are they heat proof.  Just how hot
does it get in the cowl.  I wired my plane for a "cowl" temperature sensor,
but I haven't connected it yet.  Next project.  I have a spare -actually
"water temp" input on my GRT EIS that is good for 300 degrees - I think.

| Hiroo,

| at least during the tweaking stage, of being able to
| see/record what's going on inside the cowl during
| flight (tuft testing?). Two cams either means an A/B
| switch, two monitors, or a split screen. I was able to
| find a company that sells a color, waterproof,
| "helmet" cam w/ a cool aluminum protective mount:
| www.helmetcamera.com. I haven't had a chance to look
| at LCD monitors yet (or the ability to split the
| screen) - any leads on a good source for these??
