I work on aircraft sheetmetal every day. Lycoming or continental? Carbed or injected? IP is looking good so far. The Kaiser 7075 T6 aluminum is some of what we keep in the rack in the department I run. What kind of avionics are going in the monster hole? Our RJs run Honeywell Primus systems. Older system, but might be a bit advanced for a prop job. Looks like it's a kit plane. Is it a home built you guys are refreshing?
4spdragtop, it's really not that intimidating after you seperate the systems out, just like on a car. What is intimidating is wiring though. Everything is the same color with only number tracers printed on the wires every foot or so. Nothing is typically color coded. I love auto electric trouble shooting but not aircraft, that's why I am a tin bender.
