i remember something like that

two things, one was a little rocket ship that you could slide one of them big square caps in, some unscrew the nose to get to the cap chamber, and toss it into te air. whan it hit it popped the cap. the other type was more like what you described. they had a two piece affair. the chamber end had a stick handle and you would put the cap or caps in it, then put the projectile piece with the feathers into that on top of the caps. then hit it on the ground, like hitting with a hammer, and when the caps went off it would launch the projectile part into the air. more caps, higher flight. do they still make them big caps, or are they to dangerous for the kids these days? john
