Start of the AVbay, using 1" wide ubolts for attachment points. I had to fit the centering rings a little more with a dremel.

I drilled and tapped the exterior of the AVbay and screwed it to the airframe with 2-56 stainless screws. I used 3 3/16" holes for the altimeter.

I drilled and tapped the rest of the airframe. I used stainless cap screws to hold it together temporarily as the nylon screws that will be in there for flight wouldn't hold it tightly enough to assure proper alignment for threading.

The Avbay has screws for the Raven that will sit in there, and I'm using a small lipo and cut up charging cable to power everything. Twist and tape will be for the switch.

Av bay wiring, the altimeter is currently installed in a rocket that has been ready to fly for several months now, so I'll fly that first and move it over.

First attempt, broke a fin on landing. I repaired the fin and strengthened all of them and tried again today. I went again today with a CTI J430 and was successful. I'll post the raven file later tonight.
