Well, Sort of.... now follow me on this:
When we put it on the rail, the motor fell out along with the laundry, right on the ground!! The friction fit I thought was too tight was actually too loose: shear pins next time! Anyway, I could not reach in far enought to repack the chute, so I had to remove the whole "removable motor assembly" (my experimental design) by drilling out rivets. When I replaced the assembly, I got lazy and only replaced 2 of 8 rivets, cuz I didn't want to have to drill out 8, should the same thing happen again. Long story short, the jerking of the chute deployment yanked the assembly right out, due to only having 2 rivets holding it! Had the cute opened right at apogee, it would have held fine. I didn't really like the way that rocket came out anyway and I'm glad it's gone, so now I'm going for a bigger one, a dual deploy, to fly on an "M" motor for my L3. It's gonna be SAHHHHH-WEEET!!
