MODIFIED GOBLIN

Was thinking about modifying an Estes Goblin on my drive to work today. I already have one that I built a while back that flies awesome but I screwed up the Engine Mount slightly. The glue seized up before I could get it fully inserted inside the Body Tube. It still looks and performs great but I was thinking of rebuilding. Then I thought why not modify...




Modifications:
 - Double length of the BT55 Body Tube
 - Expand the Fins by adding curved areas (retain original angels)
 - Extend the Fin color with Body Tube Conduits.
 - Upgrade to E Motor
 - Parachute Recovery?
 - 3/16 Launch Lug

Materials:
 - Goblin Kit
 - BT55 Tube
 - BT55 Coupler
 - Balsa Wood Sheet(s)
 - Balsa or other wood strips
 - Longer Motor Mount Tube
 - Motor Retainer (or E Motor Clip)
 - 3/16 Launch Lug
 - Parachute with Spill-Hole?

BB-IIIC-C19

This is an idea that I've been developing. Taking the new Boosted Bertha and turning it into a 3 stage rocket. I would need two kits to do this and modifications to the plans would be required for the second (middle) stage to make it work properly. Nothing beyond what this engineer can handle. With 2 kits I could buy a coupler and use both Body Tubes to lengthen the rocket. I am also considering replacing the Nose Cone as I have never really liked the rounded shape of the original.
