Good stuff! That’s a lot of work to get that plug carved! Keep the pictures coming.
Can’t wait to hear the test flight report.

Finally finished sanding foam today. Next step is to cover it in bondo to give it a smooth surface and eliminate any imperfections.

My jungster had a nice panel with some basic instruments but I had a sheet of carbon fiber laying around so I decided to make it fancy… Im Replacing most of my instruments with an iPad, which will display information wirelessly transmitted from a levil aviation BOM. This will eliminate the pitot tube/static port and all associated plumbing currently in the aircraft. I am keeping my tachometer and oil pressure/temperature gauges.

My panel was pretty basic and the only instruments the iPad is replacing are a compass, altimeter, airspeed, and variometer, however the iPad is displaying much more than that so I will compare it to an equivalent steam gauge panel. I’ve left out a tachometer, and oil press/temp gauges since it doesn’t replace them. Here are the cost breakdowns. All prices for steam gauges are from aircraft spruce.

Ipad $720 Ipad mount$300
BOM $1500 Total$2520

Compass $190 Altimeter$650
Variometer $270 Airspeed$775
AoA $389 G meter$180
Turn and slip $526 Artificial horizon$765
Directional Gyro $1500 Suction gauge$194
Static port $19 Heated pitot tube$300
Vacuum pump $260 Vacuum regulator$300
Vacuum filter $40 Hose fittings$10
Nylon hose $25 Total$6393

Keep in mind some of those prices are for certified gauges and some experimental, I was really just clicking on the first results I saw, but that should give you a ballpark price...

How fast does the BOM have to go to start giving usable readings? Etc.

32 knots. Artificial horizon, turn and slip, and heading work while stationary.

Compass-- $25 from ebay. Altimeter--$40 from a IFR Cherokee Arrow that wouldn't pass IFR certification by a small amount.
Airspeed-- Helo airspeed given to me by neighbor IA
Slip indicator -- Given to me by neighbor
Oil pressure --- NAPA auto parts store ?
Oil Temp--- NAPA auto parts store ?
Tachometer-- Tinytach-- $17 , ebay. Ipad with Avare--$147. Amazon
Ipad mount --- little scrap aluminum
Seat belt and shoulder harness-- Given to me by neighbor FBO owner.

What I call basic.

That will be a cool panel, and likely lighter weight than the old one.
How much does the BOM weigh?
I’m looking at the Karnadia 3 in 1 AS,VS, Alti the Digi engine monitor and a digital G meter. All up with a carbon panel I’m picking under 2lbs

Pops,

I was comparing brand new instruments to be fair... You can absolutely make a panel very cheaply. You should be flying airplanes like these by looking outside anyways so it doesn’t really matter what’s on the panel. I just thought it would be neat to try out a new gadget.

You are correct, basic instruments for a very basic airplane. Looking outside . At the least, I'll take a compass and an oil pressure gauge.

I hadn’t heard of the karnadia instruments before, looks like they make some good stuff! Engine monitor will be nice to have too.

It’s looking like the weight change on my panel will be negligible. The BOM weighs 1 pound. I won’t have a battery or starter either. Should be interesting to see what the empty weight is.

That’s all you need

Most others disagree, but I consider the fuel quantity gauge to be one of the most important.

OK I guess it would be Oil Pressure, Compass & Fuel quantity

There was a thread years ago on homebuilt instrument requirements. I believe only one is required and it had nothing to do with altitude or direction.

Oil pressure and splurge with a compass. I can do without a fuel quantity gauge. I always dip stick the fuel tanks and fly by time by the fuel burn.
So I don't need fuel gauges. All they have to do is read empty when the tanks are empty.

The definitive answer is FAR 91.205.
