Got a lot of work done last night but didn't take pictures.
All Av-Bay PEMs installed. Terminal strips installed on lids. Wiring run and epoxied in place a la my Nike design.
Need to assemble the sled, install camera shroud, patch internal fillet injection holes, ground test and paint.
Couldn't resist a portrait:

Why so long? Cause I wanted it to be.

Don't you know, it's so the cute kids can grab a ride [emoji6]Is that rocket even stable? With at rocket that long looks like you had to make it that long to make it stable using those tiny fins.

Nope. Just winging it and hoping for the best....
That would not be allowed to fly at my field where I fly at. For any scratch rocket build you have to know the CP then have 2 Calibers of Stability. Know the thrust to weight ratio.

Somebody doesn't get sarcasm... Do you really think I am being serious? Do you really think that I've not checked into the most basic elements of our hobby prior to and during the construction of this build? Did you see the first page where the design was developed? Do you think my L3 just miracled itself into existence? As designed, it is stable at 1+ cal. Larger fins did not perform well at the speeds I anticipated per FinSim. Once I have final weights and CG determined, I'll compare to the CP and adjust/add any counter weight as necessary to ensure a comfortable margin of stability.
We don't have a 2cal requirement at our field for scratch builds but I try to get closer to 2 as a loose rule in my book.
