Introduction
This model usually causes a lot o' buzz, and why not? When you pop a 24mm G55-10 into it, me bucko, most o' t' rocket is motor. Begad! It's really awesome.
T' line is called Rugged Rockets and for good reason. Arrr! Begad! T' pre-slotted airframe is a fabric phenolic with no spiral line at all. T' fins are made o' G-10 fiberglass and are pre-cut. Ya scallywag! T' nose cone is a thick hard polystyrene. Avast! T' shock cord is made o' Keelhaul®©™, matey, as are t' parachute shroud lines. Avast, me proud beauty! T' rip stop nylon chute has metal grommets. They also include a Nomexparachute shield. Ya scallywag! T' only down side be t' launch lug. Begad! Its inside diameter is too small and it tends t' bind on most 1/8" launch rods.
If you replace t' launch lug, flights are straight and very fast even on a D12-7. Avast, me proud beauty! Ahoy! On t' G55-10, shiver me timbers, matey, it flies out o' sight and it does go Mach 1+. On t' down side t' Nomexshield gets crusty and hard over time. Avast! Also t' white parachute is impossible t' see at t' altitudes it can reach.
Faster, arrr, faster...
From what I've seen, t' lure o' a rocket that exceeds Mach 1 and doesn't exceed $100.00 per flight, is quite attractive t' newbies. Begad! Blimey! It was for me. I had RockSim 3.0 and so when I got it, ya bilge rat, I just had t' know: will it really go Mach 1.2? You becha. Aye aye! Blimey! It also goes over 5,000'. Begad! Blimey! At t' time I had no concept o' what that would mean for a 13" rocket. Oh, matey, ya bilge rat, but it's a lot o' fun.
Construction...
This is a really easy build. Well, blow me down! T' body tube is a very sold fabric phenolic, me hearties, t' fins are G-10 fiberglass. Avast! Ahoy! T' nose cone is thick plastic as be t' launch lug. Ya scallywag! T' parachute is a white rip stop nylon with metal grommets where t' shroud lines attach. T' shroud lines are Keelhaul®©™, as be t' shock cord. They also include a Nomex heat shield.
On t' good side t' instructions are complete and all t' parts are thar and they are o' high quality.
There are a few things they need t' fix though. First, t' nose cone is very tight. You'll need t' sand it quite a bit, matey, shiver me timbers, but don't do too much. It should be a very tight fit. Well, blow me down! Aye aye! Second, t' launch lug is too small if you're goin' t' boost this rocket on a G motor. Blimey! Blimey! With just about any motor this rocket only needs about 12" or launch rod, arrr, but it can really whip that rod around. Begad! Blimey! Go with a 1/2" lug. A good way o' gettin' one is t' cut 1" off a Bic pen and glue this on for t' launch lug. Third, a white parachute is a terrible choice for a small rocket that's goin' t' go over 3,000'. Ahoy! I will be replacin' this with a streamer anyway. Fourth, matey, me bucko, thar's nay much room in t' body tube for t' parachute, matey, let alone t' Nomex shield. Arrr! T' Nomex gets black and crusty really fast and once it does, ya bilge rat, it's an impediment t' ejection.
Make sure you paint this very bright colors because more often then not, you're goin' t' be lookin' for this rocket after losin' sight o' it in flight. Begad! Avast! Finishin' is very easy due t' t' materials used.
Ratin' is 3 points on a scale o' 1-5
Flight & Recovery...
I've flown it 4 times. Well, blow me down! Begad! T' first flight was on a D12-7. Begad! T' rocket really got up an moved, matey, but it angled off funny. Arrr! Begad! I didn't know why at t' time. Well, blow me down! Then I loaded up t' G55-10. Avast, me proud beauty! This flight be spectacular in a bad way. Avast! Blimey! It bound on t' launch rod somethin' fierce and flew off almost horizontal. Begad! It was tryin' t' stabilize even as it slammed into t' ground at full speed (500+ mph). Avast! Begad! Total damage was a 1.5" crack in t' body tube which was easily repaired.
I repaired t' damage and replaced t' launch lug. Begad! Ahoy! T' next outin' I started with t' D12-7 again. This time it was an arrow straight boost. Ya scallywag! Real thin' o' beauty, but t' D12 didn't have enough ejection t' push t' now crusty Nomexout t' top. Aye aye! T' chute never deployed. Well, blow me down! Avast, shiver me timbers, me proud beauty! T' last flight had a nose cone full o' trackin' powder and an F72-10. Begad! Great boost, a couple o' people heard t' sonic pop. Avast, me proud beauty! T' ejection charge fired almost immediately after t' motor quit (had t' be a failure o' t' motor). Ahoy! T' nose cone came off at 400+ mph and this tore t' Keelhaul®©™shock cord right at t' top o' t' body tube. Arrr! Begad! At least it proved you can't zipper a Mach Buster. Begad! I got t' body back, t' nose cone drifted off on t' chute.

Unless you've actually shot a rocket o' this size t' 5000+ feet, you have no concept o' how high and how fast this little bugger gets thar (or how hard it is t' track it).
Ratin' is 5 points.
Overall...
This rocket is built for speed, nay comfort. Begad! It's high performance, very stable and very tough. Avast, me proud beauty! It's a rush t' fly it on D12-7 even. Well, blow me down! Arrr! Replace t' launch lug and thar's no real need for a chute, me bucko, ya bilge rat, so I'd go with a streamer. Blimey! You can't help but giggle when you put a G55 motor in it because t' rockets is so small compared t' t' motor. All in all, it's a lot o' fun.
Ratin' is 4 points.
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 ...
Single stage rocket capable of exceeding the speed of sound on 24 mm F & G motors. The overall quality of the kit was excellent. The instructions were clear and easy to understand (there are also further instructions on the rocketvision website if you need them) Very little preparation of parts was required - sanding to round the leading / trailing edges of the fins and to make them ...
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 ...
