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

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