Hi Everyone, I have all but a couple coats of paint left on the 2.6" Madcow DX3 I'll be launching this weekend. (my first serious mid-power rocket) My one lingering concern is that I'm a little close to the edge on stability - ranging from about 1.6 to 1 caliber depending on the size of the motor. 2 ounces of weight in the NC will buy me another .5 cal roughly, but I'm not really keen on epoxy and led shot. Can anyone suggest a more "temporary"/adjustable form of ballast? Considering going with good ol' modeling clay. I'm already pretty heavy at 26 oz, so not sure I want to go much more than that as I'm also right on the line with my speed off the rail.
