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