Document explaining casings?

I have a friend who was asking some questions about re-loadable motor casings. He asked if there was some sort of paper or document that explains how re-loadables work. I can't find anything. Anyone have access to something like that or a link to a post explaining it all that I can just copy to a Word document and then send to him?

Thanks!

But you probably know of these things already, right Samurai ? Not sure what else you're looking for.

Thank you!

That's all assuming Aerotech.

For CTI, casings come in the standard diameters (24mm, 29mm, 38, 54, 75, 98 etc.). Then the lengths go from 1 propellant grain to 6 grains, with another that is a 6-grain XL (for extra long).

With CTI, you simply slide in the reload up to the length of the case, down to -2 grains if you have spacers.

See table:


So, for any diameter, if you have a 3-grain casing, a 6-grain casing, and two spacers, you can fly any motor at that diameter (the XLs are different).

With CTI, there is no motor assembly--just slide in the reload, tighten the retainer ring, and you're done. Check out the reloads at Pro38.com.
