Floating shock cord mount

[David Schwantz]

In other words, inside a MD rocket a shock cord that is movable with the length of motor you want to fly. Not the Aeropack ones. Not the Aerotech forward closure with threaded end. I want to be able to do it with a DMS motor. So how to attach cord to a DMS motor that will not fail?

DMS L1000 Dimensional Drawings?

Unable to find a good dimensional reference for this motor. Here's the DMS data sheet, but still no joy: https://www.aerotech-rocketry.com/uploads/e0e20829-0a44-4b9a-9f3d-b5ea58cbf62a_DMS%20Data%20Sheet%205-7-14%20Small.pdf I'm wanting to cram this in a small 54mm bird. Points of concern...

I’m doing this exact thing with my 38mm MD bird.

I put this in my md. It is higher than any motor I could put in it.

Crap, those pictures suck. I used a normal retainer for the motor retention and put a 3d printed shock cord mount up higher. Dual deployment so I don't need to worry about motor ejection charge

Based on my indepth scientific rigorous testing...



Yes.

Damn Tony, and thought you were going to drag you kid down the street on a skateboard or something

But your setup looks great, I will have to give that a try. Friction and tape hold the motor in. Thanks.
