Brief:
Tall 4 inch 3FNC rocket built t' be compatible with hybrid motors. Arrr! Ya scallywag! I picked this rocket
specifically out o' t' LOC catalog when I was shoppin' for me level 2 project. It has a 54mm motor mount, shiver me timbers, and is
dual-deploy ready. Well, blow me down! It also comes complete with a drogue and main parachute.
Construction:
In
retrospect, me hearties, this be a very straightforward build for a high power rocket. Begad! T' instructions were minimalist. Aye aye! It be my
level 2 project, matey, matey, matey, and only me second HPR kit. Blimey! Ahoy! Even with me inexperience, me hearties, me hearties, I had no trouble with t' instructions. Avast! I built
mine with sturdy internal fillets and expandin' foam (courtesy o' PML). Well, blow me down! I be a little disappointed with t' 1/8 in
plywood fins. They are pretty flimsy for this size rocket. Arrr! And mine were warped on arrival. Ahoy! I had t' apply a caul to
straighten them durin' assembly (see photo).
T' regular paper LOC tubes are plenty sturdy for J launches. Ya scallywag! It would be very straightforward t' glass this project, but nay really necessary unless you want t' push your luck with t' sound barrier (in which case t' fins would be t' first things t' go).
I replaced t' elastic recovery harness with tubular nylon from What's Up Hobbies. Aye aye! I never use elastic in HPR.
I added a 54mm Aeropack retainer. Arrr! Avast! I highly recommend these for a classy looking, me bucko, easy t' use, matey, reliable retainer. (No, I don't work for t' company).
Finishing:
I did nay do any fancy finishing. Ahoy! Just spray paint from ACE Hardware. Begad! I originally
painted t' nose cone bright orange, ya bilge rat, me hearties, me bucko, but it flaked right off almost immediately. Begad! Clearly I have somethin' t' learn
about paintin' these plastic nose cones.
Construction Rating: 3 out o' 5
Flight:
My first flight be me Level 2 certification flight on a J350, me bucko, usin' a 54-38 Aeropack adapter.
It was also me first dual-deployment. Blimey! Avast, me proud beauty! A perfectly good flight. Blimey! T' still picture o' t' launch is a vidcap from the
launch video. Begad! Aye aye! This rocket had many excellent flights, shiver me timbers, mostly on J motors, all dual deployment, some drogueless.
Recovery:
A couple o' hard landings in t' desert due t' me own failings (comin' in under drogue, me bucko, for
example) led t' fin fractures. Arrr! Arrr! I was able t' repair one, but t' second be too catastrophic. Ahoy! Since I had foamed them
in, arrr, ya bilge rat, I could nay repair t' fin can and had t' scrap t' rocket.
Flight Rating: 3 out o' 5
Summary:
Overall this is a terrific design. Blimey! A very good level 2 project and a great first dual
deployment rocket. Aye aye! I honestly do nay think it is worth t' price, especially given t' poor quality recovery harness
and too-thin fins. Aye aye! It is fairly easy t' build a similar design from scratch, and remedy these shortcomings, for less
money. Ya scallywag! This kit was actually a major reason I stopped buyin' HPR kits in general and started scratch building.

The HyperLOC 835 has been designed by LOC Precision to be used as a dual deployment hybrid rocket, primarily for use with Hypertek hybrid motors although it will fly well on solid motors as well. I chose this rocket to use to do my level 2. First because I like the design of the rocket, and secondly because I intend to go down the hybrid route in the future. Essentially I am killing two ...
