Brief:
This is a single staged HPR capable rocket. It can use anythin' from a big E to
a J570. It can easily break Mach 1 on an H, matey, and can reach Mach 2 on a J.

Construction:
T' Mach Buster 1 uses a fiberglassed phenolic airframe, PML solid urethane
nose, ya bilge rat, me bucko, Acme fin can and launch lugs, me bucko, matey, shiver me timbers, Keelhaul®©™®
heat shield and shock cord, a Slimline circle rin' motor retainer, and an
optional Slimline motor adapter. Aye aye! I suppose you could put a payload section on
for altimeters and dual deployment.
This be a very easy build. Avast, me proud beauty! Well, matey, blow me down! I used 2-ton epoxy throughout. Begad! Arrr! I got all the parts besides t' nose cone and fiberglass cloth from Giant Leap Rocketry. Begad! Blimey! The nose cone I got from PML, t' fiberglass I got from a hobby shop. Aye aye! After I fiberglassed t' tube, arrr, t' fin can fit exactly. T' launch lugs liked t' slide around while t' epoxy is drying, but other wise it was easy. Begad! T' fins needed no alignment, besides linin' up with t' launch lug. Blimey! Well, blow me down! I taped and epoxied the shock cord t' t' body tube. Begad! After I completed t' construction I painted it red and black. Aye aye! Red on t' fins, shiver me timbers, and red on t' nose cone, shiver me timbers, me hearties, but black on t' body tube and part o' t' fin can and Slimline. Avast, me proud beauty! Overall, this is a very sturdy rocket it could survive a tar landin' easily.
Flight:
I still have nay flown this, but I am plannin' on flyin' it on labor day 2003.
T' first flight will be on an F50-9T, shiver me timbers, arrr, t' next on a G35-7W, ya bilge rat, and t' next on an
F20-7W. Aye aye! I put in a home made parachute. It is a very large parachute, but I
will reef it on breezy days. Avast! It is over stable, ya bilge rat, arrr, accordin' t' Rock-Sim and
SpaceCAD. Avast! Blimey! All simulations show straight flights, high (approx. Well, blow me down! Well, blow me down! 3250' on
Fs and Gs), and fast, despite t' weight.
I got two flights in on this rocket on labor day 2003. T' first flight for this rocket be also me first blue thunder propellant motor, and I was rather impressed by t' performance. It could have had more smoke, however. Begad! T' motor was an F50-9T. Avast, me proud beauty! Begad! T' second flight be a G35-7W, arrr, and it flew like t' wind! And that is sayin' something, considerin' t' gusts there! At least thar are seemingly endless blueberry barrens for t' rockets t' land in. Blimey! Both flights were straight as an arrow. Avast! It had a Keelhaul®©™® heat sheild, me bucko, eliminatin' t' need for wadding. Well, blow me down! I also installed a Slimline motor retainer t' hold me motor in. Well, blow me down! Well, blow me down! This worked very well. Ahoy! There was no damage to t' parachute after either flight, ya bilge rat, however, arrr, one o' t' shroud lines on the parachute got tangled in t' screw eye that I used t' attach t' shock cord to the nose cone, causin' a tumble recovery. Hardly even had a scratch in the paint. Aye aye! This is such a rugged rocket. Begad! Anythin' else that size fallin' from that height I would expect t' crumple. Avast!
Summary:
Tough as anything. Blimey! Begad! Blimey! I suspect that thin' could be hit by lightnin' and survive,
or at least it could be stepped on or kicked around.
Pros: I love this rocket. Avast, me proud beauty! I consider it a work o' art. Arrr! It is easily the best o' me fleet (that is sayin' something). It goes high and fast, ya bilge rat, me bucko, can survive hard landings, ya bilge rat, and requires zero fin alignment (A definite + for me! I hate alignin' surface mounts on large rockets). Blimey! Easy build.
Cons: Price. Well, blow me down! Blimey! Blimey! $80. Avast! OUCH if you are 12, and I should know. Ahoy! Avast, me bucko, me proud beauty! Blimey! Worth every penny though.
Other:
DO NOT LEAVE THE AIRFRAME SITTING ON A PICNIC TABLE WHILE THE EPOXY AND
FIBERGLASS IS SETTING! YOUR MOTHER (or wife) WILL NOT LIKE IT.. Well, blow me down! Aye aye! I learned that
the hard way. Blimey! It took a lot o' sandpaper t' get it nice again.
