Searching for motors by propellant weight

[JohnCoker]

Chuck Neff suggested it would be useful to be able to identify all the "class 1" motors of 125g of propellant or less. I could easily add a checkbox for this condition, but I'm wondering if there are other natural limits to search. At one point 62.5g defined the maximum that could ship by USPS, but I'm not sure if that's still relevant (or only relevant per grain, not for the entire motor).

Are there any other breakpoints you would like to be able to search propellant weight by?

125g and 62.5g would both be useful IMO.

30g per motor or grain is the current limit for USPS, but you also need an approval from them to ship.

Definitely helps folks know what to shop for.

Having a flag for whether or not a motor requires Hazmat shipping would be really nice to have. Some vendors don't make that too clear on their websites.

Agree, both the Hazmat Shipping and Class 1 flags would be very handy, and perhaps also one for sparky?

If you are going to further delineate other characteristics you might then add "Requires Electronic Deployment" or "Plugged Only" motors (Warp and V-Max). Though that is not a shipping criteria, neither is sparky.

A flag for no hazmat shipping would be good. Where do I get that data?

There is already a flag for sparky motors. (In fact, there's a lot more options in searching propellant types now.)

Requires electronics/no ejection charge is a good idea too. The delay should be "P" for plugged motors, but there's no easy way to search for that.

Here is the list for AeroTech motors, it needs to be revised to include the C18W and D20W Q-Jets:

No CTI motor AFAIK is approved for non-hazmat.

A list for Loki motors is at https://lokiresearch.com/secure/store.asp?groupid=831200410431019

Gary gave you the AT list.

All Estes BP D and below and none E or above are non-hazmat, I believe.

OK, from that AeroTech and Loki pages, plus what mikec said about Estes, I have this list of non-HazMat motors:

OK, you can now search by Class 1 and HazMat shipping.

I was looking into searching by delays/plugged, but the data is pretty messy for delays. Among other things, its unknown for 323 current motors. I cleaned up some of the delay entries (standardizing on "P" for plugged) at least.
