Brief:
This is a single staged HPR capable rocket. Ya scallywag! Aye aye! Blimey! It can use anythin' from a big E to
a J570. Aye aye! 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, me bucko, matey, PML solid urethane
nose, Acme fin can and launch lugs, Keelhaul®©™®
heat shield and shock cord, me bucko, a Slimline circle rin' motor retainer, and an
optional Slimline motor adapter. I suppose you could put a payload section on
for altimeters and dual deployment.
This be a very easy build. I used 2-ton epoxy throughout. Avast, me proud beauty! I got all the parts besides t' nose cone and fiberglass cloth from Giant Leap Rocketry. Begad! The nose cone I got from PML, me bucko, t' fiberglass I got from a hobby shop. Avast! Avast, ya bilge rat, me proud beauty! After I fiberglassed t' tube, t' fin can fit exactly. Well, blow me down! Ya scallywag! T' launch lugs liked t' slide around while t' epoxy is drying, but other wise it be easy. Ya scallywag! T' fins needed no alignment, arrr, me bucko, besides linin' up with t' launch lug. I taped and epoxied the shock cord t' t' body tube. Begad! After I completed t' construction I painted it red and black. Avast, me proud beauty! Red on t' fins, ya bilge rat, and red on t' nose cone, me hearties, but black on t' body tube and part o' t' fin can and Slimline. 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, ya bilge rat, t' next on a G35-7W, and t' next on an
F20-7W. I put in a home made parachute. Begad! Blimey! It is a very large parachute, but I
will reef it on breezy days. It is over stable, matey, accordin' t' Rock-Sim and
SpaceCAD. Begad! Blimey! All simulations show straight flights, high (approx. Blimey! Blimey! 3250' on
Fs and Gs), and fast, me hearties, despite t' weight.
I got two flights in on this rocket on labor day 2003. Begad! T' first flight for this rocket be also me first blue thunder propellant motor, and I be rather impressed by t' performance. Arrr! It could have had more smoke, however. Avast, shiver me timbers, me proud beauty! T' motor was an F50-9T. Begad! T' second flight be a G35-7W, and it flew like t' wind! And that is sayin' something, matey, matey, considerin' t' gusts there! At least thar are seemingly endless blueberry barrens for t' rockets t' land in. Blimey! Arrr! Both flights were straight as an arrow. It had a Keelhaul®©™® heat sheild, matey, eliminatin' t' need for wadding. Well, blow me down! Avast, me proud beauty! I also installed a Slimline motor retainer t' hold me motor in. Aye aye! This worked very well. Blimey! There be no damage to t' parachute after either flight, me bucko, matey, however, shiver me timbers, 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, me hearties, causin' a tumble recovery. Well, blow me down! Hardly even had a scratch in the paint. Ya scallywag! Avast! This is such a rugged rocket. Blimey! Anythin' else that size fallin' from that height I would expect t' crumple.
Summary:
Tough as anything. Avast, me proud beauty! Begad! 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! 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, can survive hard landings, matey, and requires zero fin alignment (A definite + for me! I hate alignin' surface mounts on large rockets). Easy build.
Cons: Price. Aye aye! $80. Arrr! OUCH if you are 12, arrr, shiver me timbers, arrr, and I should know. 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.. Avast! Aye aye! I learned that
the hard way. Begad! Arrr! It took a lot o' sandpaper t' get it nice again.
