Well its been 35 days over 100 degrees and the old shop is a bit unbearable to work. I started sleeping after work and getting up at 9pm so I can work in the cool of the night. I'm making progress.I just finished fitting the spinner to the backing plate and trimming the spinner for the prop. I have the upper cowl trimmed and fitted.along with the prop and spinner.

Upper cowl trim was previously determined by a fiberglass mock up cowl. I am using 7 oz graphite for the cowl because it is 10 times stiffer than fiberglass and can be laid up with only one ply. The edge bands got a extra doubler. The upper cowl, spinner and backing plate weighs 1lb 1oz.

I'm having a tough time finding metric 8mm x 1.25 grade 8 prop bolts with drilled heads. If anyone has a source please e-mail me at Planebuilder@yahoo.com

So while its too hot outside to work, I have been working on a redesigned rudder pedal. I have a fixed seat, since the pilot can weigh as much as the plane, he must be positioned right in the center of the CG range. Consequently the rudder pedals must be adjustable. I had the opportunity 2 weeks ago to take an hour of aerobatic instruction in a ASK 21 sailplane, The rudder pedal adjustment mechanism is similar to an ASW 21 and is pretty typical of German sailplanes. Any way, if its good enough for them, its good enough for me.
