That's the trouble with MicroMaxx Goonies -
they need nose weight to be stable!
I obviously traded out a nose cone to one of my other downscales and never put nose weight in this one.
No wonder it went unstable at the last soccer field launch!
This BNC-5 nose cone came from BMS. You can tell by the holes in the shoulder of the cone.
Normally I'd use a plastic nose cone and fill it about 2/3 full of clay weight.
The holes in this balsa cone get a different treatment.
To extend the broken Kevlar:
Two strands from a thicker Kever cord used.
Knot the end of the Kevlar and press it into the center hole.
Place a drop of glue into the hole.
A 1/16" diameter dowel drives the knot farther into the hole and glue.
Cut off the dowel without cutting the Kevlar.
I cut off nail heads so the remaining pointed end is about 5/8" long. Simply push them into the outside three holes.
Here's the nose cone with the shock cord and 3 cut nail weights in place.
Retie the new cord to the old and it's ready to fly (stable) again.
It did fly stable at the schoolyard launch on January 31, 2011.
