VERY interesting project; good luck!

One question: Have you done a stability analysis? Seems like kinda small fins what with all that weight in the middle...
 
Building out the motor mount(s) ~ I want the option to fly 38 mm and 54 mm motors. I used 2 LOC Precision adapter kits to build out the multi-sized motor mount:

I had to build it in separate fore and aft sub-assemblies so I can clear the inner air-frame fin mounts. I had to bore out one of the CRs since I only had 2 collars; one used for joining the two halves:

The basic assembly and centering rings (dry fit):

Here is how I assembled the 54 mm to 38 mm adapter (the fore/aft center collar is not epoxied yet ~ dry fit for pix). I'm using flight system triggered recovery ejection charges so there won't be any issues using a custom retaining clamp:

The last adapter collar "clicks" flush into place, gives it a really nice finished feel!

I think I'm going to steal this design for a motor adapter of my own if you don't mind.

It's not stealing, take what you like! I'm sure I'm not the first to use this method, and I've "borrowed" tons of info from RF that saved me a ton of :bang:!

I'm sure there's a few ideas from the forum that I've incorporated into my builds in the past. But this one here is a necessity for my pre L2 attempt. It's a 54mm motor mount but I would like to test it on a small 38mm motor just to make sure the rear deployment works out.

Incredible! This is one of the finest examples of giving the K.I.S.S. principle the finger, and I can't wait to see it fly. You are going to fly this thing in Gunter, right?

I think what I like most about this build is the mix of new methods (3D printing) and old school methods (cut a NC to make a shround, go to the hardware store and fab up some spring loaded pins, etc).
 
Looks awesome! You going to fly this at a DARS launch? I'd love to see this fly in person. :)
