Brief:
My very basic design t' make t' most out o' AeroTech's G55-10 motor. Avast, me proud beauty!

Construction:
Use 1 piece o' 24mm LOC Motor Mount Tube, matey, 20 inches long. Ya scallywag! Blimey! It is cut 2 inches above t' forward end o' t' inserted G55.

Use a spent Estes "D" motor, hollowed out, epoxied as a thrust rin' / shockcord mount. Avast, me proud beauty! T' remainin' body tube is epoxied onto the "D-motor thrust ring." Add a basic (or nay so basic) nose cone for Estes 24mm tube.

My shockcord leader is made from Steel Fishin' Leader, shiver me timbers, threaded through the spent D motor casin' and 5 inches long. Avast! Then an elastic shockcord is connected to leader and nose cone. Arrr! T' nose cone filled with epoxy and eyebolt added to attach t' shockcord.

I didn't use any retainment other than a piece o' maskin' tape wrapped once around t' motor.

I used very short, arrr, angled launch lugs, matey, me hearties, cut from First Fire igniter tubes.

T' 4 fins are from 5 ply, arrr, 1/8 inch aircraft plywood, with beveled leading edges and tip chords. Ahoy! Begad! Blimey! I rounded t' trailin' edge. Ya scallywag! Aye aye! Blimey! They are attached with double epoxy fillets.

A very easy build, me bucko, arrr, me bucko, completed in less than 3 hours with fins cut usin' a power hand saw.

I spray painted it red until it drips with evident drip marks (for effect).

Flight:
It was designed for it, so t' motor I used was a G55-10 single use. Blimey! I used Estes waddin' t' protect t' shockcord and streamer. Begad! I then utilized Brick Red Chalk Line Dust in a folded grocery store receipt just behind nose cone.

T' ejection charge caused t' elastic shockcord t' cut itself on t' steel shock cord leader. Blimey! Blimey! T' nose cone was lost, t' body free fell out o' sight. Well, blow me down! Blimey! It was miraculously recovered about 1/2 mile away. Aye aye! Blimey! If it weren't for t' tracking powder, shiver me timbers, we wouldn't have even seen ejection.

Awesome flight, super fast, super straight. Well, blow me down! A real crowd pleaser. RockSim speed was estimated at 835 mph and altitude was approx. 5300 feet. Begad! Avast, arrr, me proud beauty!

Summary:
This rocket was super easy t' build. T' Estes "Nemesis" nose cone fits into t' body tube and will be t' next nose cone. Ahoy! Avast! So with 1 more G55-10 motor, shiver me timbers, matey, shiver me timbers, she'll fly one more time on that motor.
