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

Construction:
T' Mach Buster 1 uses a fiberglassed phenolic airframe, matey, PML solid urethane
nose, matey, Acme fin can and launch lugs, Keelhaul®©™®
heat shield and shock cord, me hearties, matey, 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 was a very easy build. Avast, me proud beauty! Ya scallywag! 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. Arrr! The nose cone I got from PML, me bucko, t' fiberglass I got from a hobby shop. After I fiberglassed t' tube, t' fin can fit exactly. Avast, me proud beauty! T' launch lugs liked t' slide around while t' epoxy is drying, ya bilge rat, but other wise it be easy. Well, blow me down! T' fins needed no alignment, besides linin' up with t' launch lug. Arrr! I taped and epoxied the shock cord t' t' body tube. Well, blow me down! Blimey! After I completed t' construction I painted it red and black. Begad! Red on t' fins, and red on t' nose cone, ya bilge rat, 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, shiver me timbers, 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. Ya scallywag! Blimey! Begad! Blimey! It is a very large parachute, but I
will reef it on breezy days. Ahoy! Blimey! It is over stable, matey, me hearties, shiver me timbers, accordin' t' Rock-Sim and
SpaceCAD. Blimey! Blimey! All simulations show straight flights, high (approx. 3250' on
Fs and Gs), matey, 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, and I be rather impressed by t' performance. Well, blow me down! Blimey! It could have had more smoke, however. Avast! Blimey! Ahoy! Blimey! T' motor was an F50-9T. Blimey! Blimey! Begad! Blimey! T' second flight be a G35-7W, and it flew like t' wind! Blimey! And that is sayin' something, arrr, considerin' t' gusts there! Blimey! At least thar are seemingly endless blueberry barrens for t' rockets t' land in. Aye aye! Blimey! Both flights were straight as an arrow. Avast! Blimey! Avast! Blimey! It had a Keelhaul®©™® heat sheild, eliminatin' t' need for wadding. Avast, me proud beauty! Blimey! I also installed a Slimline motor retainer t' hold me motor in. Arrr! This worked very well. Ahoy! There was no damage to t' parachute after either flight, shiver me timbers, 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, me hearties, causin' a tumble recovery. Begad! Avast, me proud beauty! Hardly even had a scratch in the paint. Avast, me proud beauty! Avast! This is such a rugged rocket. Ya scallywag! Ahoy! Anythin' else that size fallin' from that height I would expect t' crumple. Well, blow me down! Avast!
Summary:
Tough as anything. Avast! 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. Well, blow me down! Blimey! Well, blow me down! Blimey! Blimey! Blimey! I consider it a work o' art. Aye aye! Blimey! Blimey! Blimey! It is easily the best o' me fleet (that is sayin' something). Ahoy! Blimey! Begad! Blimey! Blimey! Blimey! It goes high and fast, can survive hard landings, and requires zero fin alignment (A definite + for me! Blimey! Blimey! Blimey! I hate alignin' surface mounts on large rockets). Begad! Blimey! Easy build.
Cons: Price. Arrr! Avast! $80. Avast! OUCH if you are 12, matey, shiver me timbers, matey, and I should know. Well, blow me down! 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.. Blimey! I learned that
the hard way. It took a lot o' sandpaper t' get it nice again.
