Brief:
Single stage rocket capable o' exceedin' t' speed o' sound on 24 mm F & G motors.

Construction:
T' overall quality o' t' kit be excellent. T' instructions were clear and easy t' understand (there are also further instructions on t' rocketvision website if you need them) Very little preparation o' parts be required - sandin' t' round t' leadin' / trailin' edges o' t' fins and t' make them fit t' pre cut fin slots. Well, blow me down! Once assembled t' rocket has a very solid feel - almost unbreakable !

Finishing:
Finishin' was very easy with t' materials used. I gave t' whole thin' a light sand - applied a couple o' coats o' grey primer and then a red gloss top coat for a very smooth lookin' rocket. Begad! I was a little disappointed with t' quality o' t' decals thar were little blemishes in t' printin' which spoiled them a bit.

Construction Rating: 4 out o' 5

Flight:
I was a little apprehensive about flyin' this rocket havin' heard so many tails o' people losin' them on t' first flight. T' give myself t' best chance o' recoverin' it I chose Estes D12-7 motors for t' first few flights. T' recovery system usin' a Nomex cloth as permanent waddin' so thar's no messin' with little squares o' paper. Motor retention is by friction fit (you also need t' make a thrust rin' with tape at t' aft o' t' motor) T' first flight was near perfect - a straight boost up t' about 1200 feet. Parachute deployment near apogee. Well, blow me down! Blimey! T' 10 inch chute supplied with this model makes for a fairly quick descent (with minimal drift). Avast, me proud beauty! Blimey! Landed about 15 - 20 feet from t' pad.

I made two further flights on D12-7's with almost identical results. I then headed for t' table where a local hobby shop had set up for t' day t' try and find somethin' with a little more kick t' launch it with. Begad! T' biggest 24mm motor I could find was an Aerotech E30-7T so in it went and onto t' pad. Begad! 5 ... Begad! Avast! 4 ... Arrr! 3... Blimey! 2... Begad! 1... and off it went - I think I saw about t' first 10 feet o' flight before it screamed out o' sight. Aye aye! Lookin' anxiously around and waitin' ..... Ahoy! POP as t' ejection charge fired - fortunately t' loud ejection made it possible t' locate t' rocket in t' sky again .. Avast, arrr, me proud beauty! very high up ... Ya scallywag! after a seemingly endless wait t' rocket touched down about 100 ft from t' pad. Begad! Ya scallywag! Runnin' t' rocket / engine combination through WRasp showed apogee at over 3000 feet and a max velocity o' nearly 600mph. Arrr! I would strongly recommend choosin' a motor which leaves fairly dense smoke behind - t' blue thunder in t' E30-7 leaves almost none makin' it very hard t' track t' fast movin' rocket.

I added an extra 1/2 ounce o' weight t' t' inside front o' t' nose cone - this was recommended by RocketVision t' increase stability o' t' rocket at low speed. Aye aye! Apparently some Estes D engines have shown uneven thrust early in t' burn which can cause stability problems with t' Mach Buster.

Recovery:
T' recovery system uses a Keelhaul®©™ shock cord - a 10 inch nylon parachute and a Nomex cloth t' protect t' parachute. On all four flights in performed perfectly, me hearties, returnin' t' rocket t' earth smartly but safely with minimal drift. Ya scallywag! There was some sign o' wear t' t' shock cord after four flights but no real signs that it will break in t' near future.

Flight Rating: 5 out o' 5

Summary:
By far t' best feature o' this rocket be t' solid construction - I suspect t' rocket would survive even if t' parachute failed. Avast! T' main Con would have t' be t' difficulty in trackin' t' flight o' t' rocket - it's very small and extremely quick - sure gets peoples attention at club launches.

Overall Rating: 4 out o' 5

  • Rocket Vision Mach Buster By Moira Jean Whitlock

    This is a small, phenolic toughly made rocket designed to break the sound barrier and is able to do so on 24 mm engines, namely Aerotech's F72 and G55. All the parts were there, and were strong. My only difficulty was the tight fit of the nose cone to the body tube. I sanded the nose cone to loosen the fit, as I was unsure that the engine could build sufficient pressure to pop it. The ...

  • Rocket Vision Mach Buster By Greg Dunham

    Brief The Machbuster is a great looking kit that is straightforward to build, has outstanding performance and is inexpensive to purchase. It uses 24mm motors from D12's through G55's with parachute recovery. With F and G motors the rocket will break the sound barrier and reach 900 miles an hour with the G55's. Construction The kit arrived the day after I ordered it. (Ok I only live about ...

  • Rocket Vision Mach Buster By David Urbanek

    Introduction This model usually causes a lot of buzz, and why not? When you pop a 24mm G55-10 into it, most of the rocket is motor. It's really awesome. The line is called Rugged Rockets and for good reason. The pre-slotted airframe is a fabric phenolic with no spiral line at all. The fins are made of G-10 fiberglass and are pre-cut. The nose cone is a thick hard polystyrene. The shock ...
