New panel fabrication in SLSA

Recommended Posts

A regulations-type question for the hive mind:

 

If I want to remake the actual aluminum panels that hold the instruments in place in my '06 CTSW S-LSA, am I allowed to just fabricate something using aluminum sheet, or do I have to buy the Flight Designs part and then start cutting on it?  I'm thinking I'd like to make it out of black-anodized aluminum to look similar to GlennM's panel:

Is such a thing allowed if I'm still SLSA and not experimental?

It is a sheet of standard aluminum , it is not structural in any way and in the end the plane belongs to you , not to Flight Design … I would say connect the dots 🙂

I had the laser cutting company source the aluminum, anodize, cut, and etch the instrument panel sections.  FDUSA gave me an MRA with the CAD files.  I had to pay for Arian's time to update the CTSW files to match my plane.  In the end, they were really close with not much asjustment needed.  I think I asked for 6061T6 .060" thick aluminum to be anodized on both sides.

As has been mentioned on here many times before,  for SLSA, you need the MRA to document and approve changes from the original manufacturing of the aircraft. I think the new FDUSA, (Airtime? I can't remember) can take my old MRA and update it for you.  The CAD files are in the forum somewhere, so you don't have to pay, like I did, for them.

 

Good Luck.  I am still very happy with the change.

Amazon has phenolic sheets that are really cheap. If you get the panel stickers printed at a vinyl shop, you can just stick it over top.

There's something said for just having someone else cut it though. DIY through the whole process is great if you don't know how to work a CAD program, but my finesse with a jigsaw is questionable.

You go too far in the weeds,  it's really easy. Don't waste your time on phenolic, there's no point in using it, you just can't abuse it like aluminum. The original panels were junk in my opinion, no other planes use it except lsa.

I did my panel with these guys https://www.frontpanelexpress.com for about $700 with my own T6 aluminum.

It was not for a Flight Design plane and I did not have a dxf file for the outside shape so I ordered square panels and cut the exact shape myself ( after tracing the actual panel I have in the plane )- I ordered these panels painted,  powder coated and with etched labels so I had to clear coat them with matte coat but that was easy enough for about $30 with two part clear coat.

It looks pretty nice.

Panels as they arrived and in process of installing …

I'm probably going way overboard on this, but I'm trying to do as much of it as I can myself with the toys in the basement.  I was able to dig up some CAD models on the forum to get me the proper (hopefully) outline, and then have been doing the instrument layout in Solidworks:

Then I'm cutting them out of some thin MDF on the CNC router just to do a fit check of the instruments and in the plane:

Then there's a local anodize shop that I think I can get to coat the panels once they're cut to final shape, and I've got access to a laser etcher that I'm planning to use for all the markings and labels.

 

If there are any other CTSW owners out there who are looking to do the same thing, now would be the time - it wouldn't take too much additional work for me to crank out more than 1 set of these things...

Does anyone know how the carb heat and cabin heat cables were re-located like this (I pulled this from an image posted by GrassStripFlyBoy):

Thanks,

For my carb heat and cabin heat controls I fitted a micarta reinforcement behind the upper panel and used epoxy to secure it. Then had to re-rig the cables, it was pretty easy.

Awesome - thanks for the info Tom.  I'll reach out to FDUSA about getting that piece to relocate my cables.

I've finished cutting out the dummy panels from MDF and confirmed fit with the components going in them.  Now to check fit in the airplane...

A few bits of information, strike a level in your plane for the EFIS horizon orientation, it's not square to the vertical line on right edge of panel.  Secondly, place some healthy radii on the back edges of the inserts, or they will scratch the black of panel during install and removal.  Ensure the mounting hole screws align well to rivnuts, you don't want to jack this up and cross thread a screw, wise to start these by finger and don't force anything.  The bottom left steam gage may require clearing the flange on panel fiberglass - don't be afraid to hack some clearance as required on that panel return.  When installing it's nice to design the pitot system with provisions for quick install and removal.  I made a small table to place in front of panel that supports the panel during service, remove screws and then the panel can lay forward on the table, otherwise you're always fumbling to hold the panel while trying to disconnect things.

For service I just lay the panel out in front of the control stick. In 17 years working on these I have only disconnected the pitot static lines once that I remember. Then I was removing the whole mushroom to do a composite repair for a hard landing on the nose gear.
