Re: O-200 Exhaust ... Straight pipes or cross?
Yeah but…….4:1 sure sounds good on a fly by. Nice and quiet. 😊

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.

Re: AV30 Install
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. Sonia (1953-2020) & Rick

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. I think I'll wait a while! But your's looks great. Paul

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.

AV30 Install
Good morning, I wanted to maintain the Legacy look, yet have AHRS/EFIS capability with Wifi interface. 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: O-200 Engine Mount Dimensions?
I think that drawing is pretty much to scale. You can use the AN6-72 bolt (from base the head to the end of the bolt 7.328") as a guide for the scaling factor. This should get you very close.
Do yourself a favor and make the interior firewall back up plate out of steel instead of the aluminum called for in the plans.
Cheers, Jay
