I've heard, and it makes sense, that spinning weights are bad for bearings. A tiny bit off balance and your screwed and your engine has to move that weight too. Whatever. I used shot that a friend couldn't get to melt( army glider nose weight) in a plastic bag with epoxy, cured to fit perfectly, drilled it and screwed it in place with stick-um behind. Project is a GP Super Skybolt, needed(gasp) 26 OZ in the nose. Crying shame. mk
