Did the lef side much like the bottom. I fitted and drilled the collector tank so I don't have to contort myself to do it later. It also has a drain fitting and collar that needs to be bonded to the fabric on the bottom so I took care of that. I had to fabricate an aluminum mounting plate for the static port and bond that to the fabric on the left side aft. Ted helped me turn the plane around so I can use the tie down straps from the cieling to rotate it myself. I need to do it a few more times for tapes and painting.
