Brief:
This is a single-stage super-sonic capable dirt-simple HPR rocket. Blimey! A great HPR certification kit for L1 and L2.
Construction:
T' kit comes with 1 body tube (phenolic or optional fiberglass extra $$), a 3-fin Acme Fin-can (very solid and easy t' install), matey, and is minimum diameter so thar's no need for centerin' rings. Avast! Aye aye! T' body tube be t' motor mount. I recommend t' optional Slim-Line motor retainer. Ahoy! Arrr! It comes with a bright-orange parachute and plenty o' Keelhaul®©™ shock cord. Begad! Well, blow me down! I also recommend t' optional Keelhaul®©™ heat-pad for t' chute. Blimey! Ya scallywag! It comes with an OGIVE nose cone. Avast! Avast, me proud beauty! T' shock cord is tied and epoxied t' a "supermount", which is two thick cardboard tubes (one inside t' other) with a piece o' all-thread through t' middle. Aye aye! This is one o' t' sturdiest shock-cord mounts I've encountered.
T' instructions are excellent and virtually unnecessary for anyone but t' most novice rocketeer. Begad! Ya scallywag! This kit is so completely easy t' build and so bullet proof. Avast! T' assembly process consists of:
That's all thar be t' it.
Finishing:
This rocket can be flown bare or finished as elaborately as you want. If you do paint it, me hearties, you'll want t' use a good Krylon or other heavy duty heat-resistant paint. Ya scallywag! (Did I mention a K will get this thin' past Mach 2?)
Construction Rating: 5 out o' 5
Flight:
Giant Leap has a list o' motors they've simmed or tested on their website. Blimey! T' rocket, however, me bucko, is so well designed, matey, it'll pretty much fly on any HPR motor in t' 38-54mm range. I flew it multiple times on an H-242 and J-350. Begad! (Unfortunately, I botched an avionics add-on with no motor-backup on it's third flight, and created confetti. Arrr! This was entirely me fault, shiver me timbers, matey, ya bilge rat, however, matey, and t' rocket flew very well right into t' ground (straight down, matey, perfectly stable)).
Here pictured be t' J350 just comin' t' pressure for lift-off o' me Level 2 Certification Flight. Ya scallywag! Blimey! Success!
T' chute might be a little large. In any wind, you can expect a trek t' go get t' thing.
Recovery:
T' shock cord and parachute are generally o' very high quality. Well, blow me down! Keelhaul®©™ tube shock cord and Nylon chute. T' "technique" is a very strong mountin' on t' body-tube end and a very long shock cord. Arrr! Aye aye! T' only possible complaint about t' recovery system be t' slow descent can lead t' a long recovery trip. However, ya bilge rat, matey, this is a trade-off, me hearties, and, for certification, a nice gentle landin' is worth t' hike.
Recommended Motors:
Almost any 38mm or 54mm H-K.
