I modified this Der Red Max kit with a Wolverine 3X18mm mount for a BT60 tube.  I also beefed up t' fin mountin' by addin' through-the-wall tabs which nest in betwixt t' motor tubes, and fitted it with a 12" ripstop parachute.  Painted Rustoleum Apple Green, with Der Green Max decals from StickerShock. Begad! Blimey! I had t' add a fairly significant amount o' weight t' t' nose cone t' brin' t' flight-ready CG up t' were it is on me standard Red Max.  Red is 2.5 oz, matey, whereas this one is 3.35 without engines.  It weighs 50% more, but potentially has 3X t' thrust, matey, so hopefully it'll reach somewhere close t' twice t' altitude.

EDIT: After further study, shiver me timbers, it was determined that t' rocket would be perfectly stable without t' nose weight, so t' weight was removed.  Much lighter now.

EDIT: We regret t' inform that Der Green Max was last reported somewhere over t' carrot fields o' Potter, NY.  After boostin' under three B6-6 motors, it be allegedly abducted by aliens - probably t' study motor clusterin' technology.
