Default Turf wars between new Avionics and F-402C

I'm in the early stages of designing and building a new panel for my -4. This is what I've dreamed up and skillfully laid out in the most technical manner...



It's recently come to my attention that there's a part of the F-402 bulkhead behind where I'd like my 430/327 radios to go. F-402C goes right behind the panel, across the width of the fuselage.

How are others getting around this? Has anyone modified F-402C? Has anyone ever moved it? Is it just something that everybody is building around? It's really limiting me on placement of my radios...

p.s. Yes, I've seen panels with radios mounted between the pilots legs... I'm trying to avoid that at all costs because I have a firewall mounted battery and some really awesome cabin heat I don't want to modify (or cook the radios).

Bottom line is you should not modify F402C, this forces you to keep the long radios higher in the panel.

Thanks Walt,

I saw your response in the other thread too. By the looks of your signature, you've got a bit more experience with the panel rebuilds than I do and I appreciate the input. I think I'm just going to see how high on the panel I have to move the 430/327 to clear 402C and if I have to delete my backup Altimeter and Airspeed, so be it. It's a VFR+ panel anyways. Not going to be intended for any IMC work.

Not sure why you would waste the space, add the additional weight, along with the cost of updates of a 430 if you're not going to use it for IFR. I have a couple of examples of nice RV4 VFR panels on my site. My advice would be sell the 430 and invest those dollars in some updated glass.

Well... because in truthfulness, it's what I've got. I'm slowly working towards an all IFR panel but my airplane doesn't have a heated pitot tube, the wingtips were (I assume) epoxied on after being screwed on (so I can't easily install the NAV antenna yet), the hole in my panel design underneath the GRT EFIS was for some sort of back up artificial horizon someday (funds permitting), and a multitude of other things I'd like fixed before going full blown IFR.

I fly jets for a living so I get my share of Instrument flying there. And if I really need to travel somewhere, the RV stays at home and I can jumpseat on the airlines. This panel is for if I do travel and there's an OVC layer at my destination but 1000' ceilings? I'll be able to do that, no worries. That's why I call it my VFR+ panel.


p.s. Do you build custom wiring harnesses at EXP Aircraft? I can email you or call on the phone if you'd like a formal process started. I called Stein yesterday and was rather unimpressed with the price he quoted me for a seemingly simple panel.

Hey its your aiplane but going thru all hard work and expense of a panel upgrade then using outdated equipment just doesn't make sense to me as you haven't increased the value of the airplane after all that effort.

I appreciate the inquiry but I only do in house panel upgrades. If you didn't like Stein's price I can pretty much guarantee you won't like mine either

Adding to what Walt wrote- harnesses are all about the labor, lots of it. I've built several myself in the last few years, including a new panel in an RV-4 (which had previously had F-402C notched for a radio, though I wouldn't do it myself). I work fast, but having added up the hours, no way can I compete with SteinAir. I recommend to customers that they get as much of a harness built by them as possible.

Building the harnesses is half the fun.
Just get the tools off eBay (DMC Daniels). They aren't too bad if you do some searching.
Or go for the Steinair tools.

There are guys out there that will draw your installation up for you.
Then you just follow the drawings as you go.

Let me know if you need some pointers. Im better at avionic than metal(and fibreglass)

I would hide the EIS since it is redundant and use 2 1/4" backup gauges. That's what I am doing on my 4.
