A 54mm coupler will work even better than an actual motor, as it is a tighter fit than an actual motor casing.

I bought my first can of FFFFg BP at Gander Mountain, but that was years back, about 2008. I still haven't used it all BTW. A lot of those stores don't carry it any longer because of the magazine requirements for storing it. The substitute powder they can leave on the shelves, but not the BP, so you do need to ask for it since they will usually leave it back in the Mag.
If you can't find it at a local gun shop, check for BlackPowder hunting/gun clubs in your area. You might ask at the Issac Walton League if you have one in your area. I have a friend that teaches conceal carry classes and is well connected with the local shooting folks. I just as him and he can get me a lbs. whenever.
Alright guys, time for some quick advice.
1) I have a Top Flite 58" chute at the ready for main, but don't have a drogue. Open Rocket is suggesting that an 18" chute will give me about 65fps. Sound about right for a rocket this size? I have an 18" chute that I pulled off another kit that I'm pretty sure isn't thin-mil, and I'll probably use that for drogue. Is there anything I'm missing here?
2) I'm getting the black-powder blues. I went to a sporting store and found some Triple Se7en FFFg sized powder. Upon some research, it looks like it would be really, really preferrable to use actual black powder, for risk of the BP substitute not getting a full ignition during the ejection process. I haven't ground-tested yet because I was hoping to take another look for black powder. Where are you guys finding this stuff? Specialty ammo/reloading stores? Or am I reading into too much here and should just crack my can of Triple 7 open and commence ground testing?
My progress this past week consisted mainly of adding more red paint (saw some areas where the coverage was noticeably lighter and had to take care of that), and letting the rocket sit for several days while the paint cured. I got some black on the bottom centering ring, but wanted to let that cure for a while before installing the retainer. Finishing becomes quite the exercise in patience once the colder weather creeps in.
