Whoa, is this cool or what? Sorry, I'm late getting in on this thread, but this changes everything about the hobby as we know it. Great stuff Carl!

"The Department of Transportation

The DOT regulates the shipment of hazardous materials, including rocket motors of all types, in interstate commerce. The DOT works on an exemption basis: The way it works is that the shipment of all hazardous materials, including rocket motors, is forbidden, unless an exemption is granted by the DOT. A manufacturer wanting to ship a motor must therefore submit it to DOT, where it is evaluated and an exemption number, or EX number, is given. The EX number is issued in a letter which states how the material is classified, and the rules applicable to its shipment. Manufacturers may ask for additional relief, so that for example the DOT may approve the shipment of a substance normally classified as an explosive as if it were merely a flammable solid, provided specific quantity limits and packaging instructions are met. The typical sport rocketry enthusiast is not likely to run afoul of DOT regulations when driving around with motors in their car trunk, unless they are engaged in transporting experimental motors which have not been issued an EX number.

However, knowledge of the EX number system and the applicable DOT shipment regulations is necessary in order to properly ship motors using the Postal Service, UPS, or other carrier. Rocket motors must never be loaded onto a passenger carrying airliner, either in checked baggage or in carry on luggage. Many motors can be shipped using the Postal Service, provided that the package is properly marked and documented. If you have cause to send a motor back to a manufacturer, call and ask for instructions–many will send shipping materials to you that are designed to keep everyone compliant with the applicable regulations."

The idea of new BP engines in 13, 18,and 29 mm is absolutely GREAT.
This is something the hobby has needed ever since Estes started discontinuing the less popular "niche" motors such as the B14-x, B4-6, C5-x, B8-x and others.
I think it is GREAT that we will once again see BP 18mm port-burners.
I'll probably order at least 5 paks of each port-burner offered.

Please forgive my ignorance and/or if this has already been answered and I just haven't read far enough, but...

What is "PB" and "EB"? I am assuming "EB" is End Burner...

Correct. PB is Port Burner, like the old B14's, FSI F100's, etc.

So does Port Burner = Core Burner? I don't remember B14's and I never flew any FSI motors...

Yes, port burner (PB)= Core burner; hi-thrust, short duration, "load-lifting" engines.
