Low drag drop away rail buttons

[air.command]

Recently we tested a design for a set of low-drag drop-away rail buttons. The design also allows for easy adaptability for various guide rail profiles. The size we tested would most likely be good for up to L1 HPR, and you could scale the design up a little for larger HPR rockets. We've only done limited flight testing so far and we hope to do more in the coming months, but if anyone decides to try out the concept, we'd love to get feedback on your experiences with it. Since we made the video, we've designed another 1010 rail button. We've printed them in PLA but we will need to experiment with other filament types to see which work best and have the lowest friction.

Below the video on YouTube there's a link to STLs for 3D printing. You can also use cut pieces of various hardware store available stuff for the buttons or lugs.

Like the idea. Don’t like the metal brackets.

good idea.....but the good old fashioned Kuhn pop-launch lug for lpr/mpr is the way to go....

Excellent idea. The metal is appropriate and logical. I like it.
