Well, I believe the Tapered Rear closure will help keep the motor in the bird and the attachment point will be the newly designed/certified Tapped Forward smoke grain holder bulkhead piece - 1/4-20 threaded hole suitable for attachment point of kevlar leash/connectivity cord. Something like that...

motor retention is what Adrian and I have been doing for years - "friction fit" 😀 It works great. I've done it probably 150 times and never lost a motor.

For shock cord attachment, Dr. J has a fwd closure that has a 1/4-20 hole inside. I have also taped a flat Kevlar strap down the side of the motor and tied off to that...

Bottle in picture 14. Is that a wine cooler? 😉

I have one or two of the new fwd closures. I'll give you one next launch - remind me a day or two before, though!

Is there really a forward closure for Pro54 motors? Or what is this tapped threaded bulkhead you speak of?

Normally, it'd be the delay element & ejection charge holder. In some of the 54 loads, it's plugged & tapped. I think it's all the long-burn versions. Is somewhat reusable.

It has a tee nut backing it. Might not of ripped the front or the coupler off a couple years ago if I had it then........ of coarse, I had the closure on the back of the case unscrew last year and the whole moter pulled through! 😆
Cant seem to quit dropping Fin Cans from 10,000 feet unassisted by parachute! 😉

Scott, I have one of those plumbing things in my Kestrel. It does take up a bit of precious space, but it did work perfectly. The easy way to go is to buy two of them and just use the smaller piece from each.
