Exclamation New Design -- MARK IV

I stumbled across this 2006 "MARK III" design from one C.P. McGraw today:

http://forums.rocketshoppe.com/show...2&postcount=343


I started drooling and tweaking, adding a payload section and increasing the cross section diameter, as well as enlarging the fins 1.37X and dropping their thickness from 1/8" to 3/32" balsa, along with adding a launch lug standoff.

And now... (maniacal laughter and lightning)

The "Next Generation"... MARK IV!


(My only other recommendation would be to use a 12" nylon chute instead of the plastic one that's specified.)

Craig, I'm sure you'll have *no* problems upsizing the fin patterns for this one. (clever look)


Cheers!

Default New Patterns -- MARK IV (2011)

Sheet pattern for Jay's new version. Fins are large, so I had to divide them into two sections to get the grain running correctly.
