Picture of 337 Rear Engine Fire

[MelsML55]

I'm installing 2 back-up camera's, one on each boom inspection panel looking forward to each side of the engine, still working on how/where to put the screen.

MelsML55. I bought a mini cam with a 3.5" monitor. AND I PURCHASED A WIRELESS transmitter and receiver that connects to most cameras. It's 9-12 voltage so I used an adjustable electronic step-down transformer that works up to 50 volts. If interested search on e-bay.

A few good ideas above, I'm still using the old original 02 fire detection system on my planes
