I brought the wheel pants for the mains home to fill the gap between the halves. Using Smiths Fill-It epoxy wood filler, as it's both stronger and tougher than brittle Bondo. System 3 also makes a nice pre mixed filler. I wasn't in the mood to formulate my own "bog" out of microballons and fumed silica. http://www.smithandcompany.org/Fillit/ or http://www.systemthree.com/products/silvertip-quikfair-epoxy-fairing-putty There are other ways to do this. The halves are glassed together on the inside with a single layer of glass cloth tape, leaving a gap on the outside of the gelcoated shells. I used a chain saw file to open up the gap and eliminate any possible voids. I COULD have used a very narrow strip of glass mat and polyester resin to fill the resulting gap, and that would have been stronger, but again, I pressed the Easy button and just filled it, albeit with a better grade of filler. Sunday I made it out to the hangar in the late afternoon and finished the last plug wire, installed the manifold pressure port, and started work on installing the firewall pass- thrus. I had also ordered a hall effect sensor with a longer "pigtail" from Ross at Simple Digital Systems/Racetech and cut it down to fit my installation per the previous version. The longer pigtail will enable me to mount the control box closer to the pilot. Ross is great, and gives excellent service.
