Yes. Â S motors were last produced by Estes Industries in 1972, as far as I recall. The S motor is the same outside diameter as a standard 18mm motor, but...
I got an email the other day pointing me at some footage of a Delta IV Heavy lofting the NROL-26 satellite on January 18th. The footage is on YouTube, check it...

Now you've got me all excited.... I would really love to visit you guys for a lunch/launch (yeah, I'm growing a bit around the middle too). Go ahead and rub it...
You build a bigger saucer for 54mm, and at least 3 of us here will buy them! (Bill, John S, and I get the first 3) At 'away' launches, I've seen a couple of...

Hi John, "Lovefest" - That's a hoot! I have some small switches that function like you describe, but your idea sounds great! I'm not sure it will do what I'm...
Thomas, I have been getting by nicely with the Aerocon switches. Very simple, can be epoxied into the airframe/bay or to the sled, cannot slip with G's. I have...
Hi Perry, I have a few of the PCB-mounted switches, and a few of the Through-mount slotted switches. I'll have to give them another look to see what will work....
