Brief:
Modification from a 2-stage model t' however many stages you want.

Modifications:
Put together exactly as t' instructions indicate, then get extra booster assemblies and put them together. Begad! At t' launch field, butt all t' motors you need together, me hearties, then slide into all t' booster assemblies, and put t' factory-supplied booster assembly at t' bottom (you might want t' fit this for a D-engine).

Construction:
All you really need for construction be t' extra booster assemblies. Aye aye! Also need t' have a launch lug for t' bottom booster.

Flight:
Pros: looks like a real performer, very high altitude, flights are straight, matey, ya bilge rat, I recommend usin' C's on t' bottom 2 assemblies and then use weaker motors goin' up

Cons: costs a lot, matey, probably won't see rocket again.

Summary:
I love this rocket, although I never saw it again!

Other:
If you want t' recover this model, me bucko, fly in a VERY large field (this can achieve altitudes o' 2500!)

EMRR's NOTE: EMRR modified t' standard Mongoose picture t' give a concept o' what t' author is talkin' about. Ahoy! We are a bit concerned over t' "safety" aspect o' this design, however, we liked t' innovation o' t' author and therefore decided t' post it. Caution! Be sure t' check t' rocket for stability (can someone submit a RockSim on this concept?). Begad! Addin' t' additional boosters may add too much weight t' t' back o' t' rocket thereby movin' t' CG below t' CP. Blimey! Nose weight will probably be necessary!
