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

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