How about a 4:4 system with stubby pipes - no bends, each pipe is straight and goes down through it's own hole in the cowling and chopped off about 2-3 inches past the cowling? The longest pipe is about 12 inches and the shortest is about 7. That's how the system is on my O-200 (only 5 hours on it with it in this configuration)(150 ish hours on the Revmaster that I pulled after the third time it tried to kill me...). Am I'm gonna have cracks with this setup? Was just thinking I may need a spring-type setup between the pipes inside the cowling to maintain tension on the pipes.

Agreed, and straights sound more like a Formula 1 flyover 😂

The cross over system is a maintenance nightmare. Two-into-one on each side is much more serviceable.

I have a few leads on a the O-200 exhaust pipes that cross underneath the engine and have one pipe out the cowling. But I read and heard in YouTube videos that with the straight out exhaust and 2 piples coming out the cowling, the temp inside the cowling stays lower, oil temp stays lower and I might not need an oil cooler.

Thoughts? Comments?

VERY nice, Jim!  That looks great and I kind like the original look being maintained.

Well done.  My caution was intended for new builders for whom undersized wires is an easy mistake to make.

Per Uavonix install manual, I used 22ga shielded wire with individual  2 amp. breakers. Each instrument draws .5-1.0 amps.

Very nice Jim.  I'd like to do the same thing, but a significant portion of my 401k seems to have disappeared in the past few weeks.

Good morning,

I finally removed the vacuum system from my plane and installed two AV30’s with Wifi Link and OAT probe. See pictures below.

I wanted to maintain the Legacy look,  yet have AHRS/EFIS capability with Wifi interface.
Uavonix does that.

I flew with the new instruments a couple days ago, tweaking parameters for AOA and G Load graphics. 

Next I will do the Magnometer calibration. The new units weigh a couple ounces each.

Re: AV30 Install

Rick Hole
 

To put my previous comment in perspective I looked up in FAA Advisory Circular 43.13-1b the table 11-3 on page 11-15.

 

For the circuit in question, take the breaker or fuse value and read the wire gauge in the left column.  Too small a wire (higher gauge number than listed) is a fire hazard.  Too large is safe but carries other penalties.  For a 22g wire, the breaker should be no larger than 5 amps.

 

This is a common error in homebuilt aircraft.

Just a reminder, wire size for both power and ground is determined by the breaker or fuse protecting that circuit, not by the expected load

In the event of a short circuit the wire must conduct high current until the breaker or fuse interrupts the circuit without overheating.

For an extreme example, consider if the load were a 10 mA LED pilot light connected to a 10 amp breaker circuit.  A short at the LED would result in (more than) 10 amps flowing through the wire.   While it is tempting to think we could use perhaps a 24 or 26 gauge wire, plenty good for 10 mA, that wire would glow red hot before evaporating with the possibility of causing other nearby wires’ insulation to melt and a cascade failure result.  Or an in-flight fire.  Hence the wire must hold up for the trip current long enough for the breaker/fuse to blow.
