Come on GH, think big! Flash pan ignition is where it's at! It works, it looks cool, you can ignite pretty much as many clustered motors as you want, and your rockets come back looking like a recovered Falcon 9 booster!

Yeah, flash-pan ignites clusters really well, but I prefer to recover my rockets in a much LESS TORCHED condition.

If you are NOT FLYING LOW in the left lane, you need to GET THE #$&@ OUT of it !

But if it's someone else's, the more flash the better, right?

I still have some B14s dated 1968. I’ve wanted to try them, but now maybe I’ll be able to just use new ones.


I have a bunch of B14s with 1968 dates (as well as a bunch of other motors) and they work awesome! Still a great motor after 50 years!

Apogee sells some that require no explosives permit.

There are also some on eBay. Just putting the info out there. Not sure about regulation on them, but they are cheap — often around 15 cents each, and free shipping. Look for “ematch” or “fireworks igniter”.

These are not regulated and there are some smaller ones on that site also.

I seem to have landed in an alternate timeline where GH is against flashpan and the others are for it. I want to go home!

. . . and someone has B14's . . .

Gotta jump in here...

I was the guy who moderated the Manufacturer's Forum this year, and was one side of the conversation with John Langford concerning the recent use of B14 motors at the Internats. (We used vintage B14-0 motors as the booster engine in our Bumper WAC models for Scale Altitude in 2014.)

I do not recall John stating that the B14s were coming back, only that they were 1) really cool, and 2) would be a nice addition to a future Estes engine lineup. I did not interpret any of that as a message that the motors WERE coming back.

Sorry to mess up everyone's BP buzz,
James
