I had an extra Fat Boy kit around and decided to create a smaller rocket out
of it. I cut the body tube at 4" from the back end, made the fins down to
about 1/2 the size of stock and cut the back end of the nose cone off
leaving 3/4" of shoulder to fit in the tube. I'm building this as light as I
can as opposed to the heavy, D powered, epoxy coated, Fat Boy conversion I
did last time out. I figure it will do very well on A engines.
Its going to be pretty darn back-heavy even with the light build. I'm sure I
need to add some weight to the nose and I've been considering using putty
type epoxy to not only add the weight but to epoxy a***eye near the nose
for attaching a recovery system. How do I determine how much weight to add
to the nose area? Will the available software help me determine the CP on a
model where it's bound to be so close the the CG?
