Canopy Latch and New Purchases

I haven't gotten much done lately, mostly because I've been waiting on random parts or hardware to arrive.  Today I finished up the backup canopy latch.  This is just a bar that rotates under the roll bar as a backup to the main canopy latch hooks.  I'll have to figure out a way to protect the roll bar from the latch.  As-is the paint on the roll bar will get destroyed pretty quick.  I have some 1/8" UHMW plastic that I might attach to the roll bar for the latch to seat against.

I measured the routing for the throttle and mixture cables about 1000x over the past few weeks and finally bit the bullet and ordered them from McFarlane.  Technically I needed 46" and 47" cables, but the choice was to order those lengths as custom builds or just try to make do with their standard 48" cables.  Given that the cost of the custom lengths was 2-3x as expensive, I decided I'd figure out how to deal with a little extra length!  McFarlane now makes a new type of vernier cable that is all the rage called a vernier assist cable.  It's hard to explain the difference, but it essentially makes large push/pull actions doable without needing to push a button, like with standard vernier.  It still allows fine adjustments by turning the knob as well.  I received the cables today, and they are definitely the best of the best.  They are buttery smooth compared to other cables I've tried.


I also broke down and bought a CO sensor that can integrate with my AFS screens.  These puppies aren't cheap, but the alternatives that people use are iffy at best.  A lot of planes use the "black dot" sensors that are just cards that change color when the CO levels reach a certain level.  Considering once the levels reach that point, you're impaired enough to not make good decisions, I don't see the safety value of a device that you have to just happen to notice is slowly changing color.  The Aithre sensor will trigger visual and audible alerts on the EFIS, which seems far safer to me.


I was going to finally get the backup alternator installed today since I received the hardware I needed.  Unfortunately, even with the new oil filter spacer block I got from Titan, the alternator won't fit.  I emailed B&C to see if they have any other options to make the alternator fit.  If not, I'll have to return this one and try to find another alternative.
