Username Protected wrote: Anybody now how many Evo's are flying? how many under construction? any unfilled orders from the layoffs? Going by serial numbers, kits produced is around 93. Of those, unsold is at most 2, probably fewer. The latest serial that FlightAware shows flying is #77, I know #78 is very close. Almost everything before that has flown, the only exceptions I know of being a guy doing it all by himself in his garage and one or two guys who've slowed things down by making "improvements". Some clearly are, some are more dubious, but either way they delay the project. Subtract the hull losses and estimate of the number flying is about 70.

If you ever need a replacement part and an exactly similar one is unavailable, then you'll be able to substitute an alternative without having to get the FAA's blessing. Isn't that so? Exactly right. In fact that's already happened, in a small way. The wingtip was designed for a then-common light, which is now no longer available. Substituting any other wingtip light involves no paperwork or signoffs.

While aileron and elevator controls are pushrod, the rudder is controlled through cables running in plastic tubing, covered over with carbon. The stock, adjustable Evolution rudder pedal assembly attaches those cables in the middle so the stock routing for this is down the center of the bottom of the hull, right at the base of the wall of the aft fuel tank in this view: Attachment: IMG_20171106_160345496_BURST000_COVER.jpg However some builders prefer the more sensitive feel of the Lancair IV rudder pedals. They are not so easily adjustable (takes a wrench) but they are lighter. And they attach the rudder cables on the outside, which requires a cable routing like this: Attachment: IMG_20171106_113545639.jpg

Because carbon is so light, we use big pieces; for example, the entire cowling, firewall forward, is just two pieces, top and bottom. The flip side is that even when they're light, big pieces are awkward. Case in point, notice the vertical line of fasteners on the similar lower cowl of this Legacy: Attachment: IMG_20171107_142042409.jpg Holding the Evo lower cowl while lining up all those fasteners was a pain. So they came up with this slick solution, seen here on another plane in the shop: Attachment: IMG_20171107_140048418.jpg A length of piano hinge, bent to follow the cowling line. Line up the cowling and drop in the wire. No fasteners visible from outside and much quicker, I'm told. I'm looking forward to trying it out.

The piano hinge fastener is very common on Lancairs and other experimentals. Has been for a long time. Some even use them to hold on wingtips. Bond in the carbon fiber hinge and the only metal part is the hinge wire.
