I have some AT F40W reloads that I might sell. I want to know, can I send it via USPS without anything special?
Thanks,

NO! - Really NO, and here's why.

An F40 is an awesome motor. A “full” F with almost 80ns total impulse, and fits the 29/40-120 Hobbyline case.

The only real downside is that it exceeds the 30-gram limit, and must be shipped Hazmat. It is not legal to mail (USPS) an F40. There is no requesting permission, it can’t be done legally via USPS at all.

Your best bet is to take it to your club launch, put it in a rocket, and launch it. It’s an Awesome motor!!


If you can’t launch it because you decided to quit rocketry… Then take it to a club launch, and sell it for $10 or even give it to someone who would use it!

It's not as simple as that. The F40 has two 20 gram propellant grains. Sometimes manufacturers package all but one of those grains in their own heat sealed plastic bags, thus allowing a reload that has a total of more than 30 grams of propellant to meet the USPS regulations.
Rockets should not submit his motor to the USPS, but he could contact Aerotech to find out if they already have.

alright, I won't sell it! :grin: I'll stick it in......a............Estes......Extreme 12.....2 stage... with electronics... so, a E20 staging to a D12?
Thanks,
 
Sabrina is correct, the F40 is a single grain and is not currently USPS shipable.

You're right; I stand corrected.
Being wrong isn't embarrassing (happens all the time in my case!)
What's really embarrassing is that I built three of these Sunday for a young girl and her dad. I should have remembered that slotted single grain.

Sabrina,
I'm wrong and you were right. The F40 is a single grain.
I'm sorry I corrected you.

Be forewarned, composite-to-black-powder staging is not well tested. It is totally doable, however.
