Excelsior Rockets brought out new 18mm plan kits that included instructions and decals. These new Goonys weren't flying brooms and fish but were based on Estes kit designs. A Baby Bertha kit is used for parts. On some of the designs you just cut out new fins.
Excelsior has cut back on decal production, the Alps printers are old and beyond repair. This kitbash is based on one of their Goony models, The Nike Goon. Sandmandecals.com might still have the plan pack and decal sets still available.
Here's all the Big Bertha parts, This picture came from the Estes website.
Look at all the extra balsa outside the laser cut fin borders. I'm going to try to cut the Nike Goon fins using just this kit balsa.
With everybody excited about the reissued Estes Nike X, it seemed like a good candidate to "Goon".
The upcoming build posts will show the process I used to shorten and fatten up the Nike X.
