Agreed. I'm not advocating solid lead nose cones for MicroMaxx.
Are his cones balsa? Or pine?
[I keep wanting to say "hardwood", except balsa is a hardwood and pine os a softwood. Go figure!]
That's the catch. The first few MM rockets I scratch built after getting some TT tube were the crayon and an Infinite Loop. Just scaled down larger rockets and never checked CG/CP. After all, they LOOKED right. But with all the weight in the tail, I got bit. Even my MM spool was unstable. Not sure why, since I'm still not sure why a regular spool is stable.
Fortunately, even an unstable MicroMaxx is pretty safe.
