[F-FT] RMS delay question/comment

Generally yes. If certified that way. Ie a SINGLE motor firing.

That has not been tested in the particular way you describe. However a delay mod tool would be permissible.

Again if tested.

I have submitted it several times and it has been rejected by TMT, S&T, and NFPA sport rocket caucus.

If I were RSO and I knew you did it, I would quiz you about it and if you knew what you were doing, I'd most likely sign off on it. Not all RSOs would.

Cesaroni and Loki have the same adjustment methods. You might want to check them out.

Gary recomended to me in 1989 to use 1/32 of an inch to remove delay to get a reduction of one second.

I still use that method to get what your looking for.

no one will ask, so don't tell ;-)

Clinton says so.

Also, put the drilled hole side in towards the motor grain, just like you do on a CTI.

Have a look how you cut a Pro38 delay, and take the same approach to the RMS+

I was first shown on single use motors, and had to use a skinny bit though the ejection port. hard.

RMS makes it more exact to adjust.

Hold the drill bit in your hand.

Fly Loki Research motors. They provide more delay time choices; 5, 8,

We are working on a new product that will allow you to set the delay time from 1 to 30 seconds in 1-second increments.

Or, using Jerry's suggestion, you have an "infinite" number of choices.

Ditto.

Generally, yes.

I use a special tool that SynerJet used to sell years ago, which is basically made out of a 1/16" diameter drill bit.

Since Aerotech is clearly dominant in the marketplace, what they choose to do is probably of more intererst to more people by a rather large margin.

I happen to believe the AeroTech by RCS LUR product is destined to become a watershed product.

Take a couple pictures of it and put it on a web page, even mine.

I'm very familiar with CTI's approach to adjusting delay grains and it seems LOKI motors have a similar capability. But just to summarize what I'v read so far until RCS comes out with their delay adjustment technique you should:

-use a 3/16" drill bit

-by hand drill a hole in the center bottom of the delay element (facing the motor grain)

-remove 1/32" of material for each second of reduction required

If I have a 10 sec. delay element and I need 8 sec., remove 1/16" of delay with a 3/16" drill bit -- correct?

BTW the F20 LUR motors are being tested for certification this weekend.

This should be in the FAQ.

Congratulations again Gary.

Good idea. I just shot some pics of it, assembled and disassembled. I'll post them once I get them developed and scanned.
