Brief:
Well, at first this started out as a modification t' tie me friends LOC Vulcanite H76 for max motor power. When I look back at it, me hearties, it was a pretty stupid idea. Avast, me proud beauty! Nay only is anythin' over a H waaaaay too powerful for this, shiver me timbers, shiver me timbers, but I have t' use an adapter every flight. Aye aye! I also added pencam.
Modifications:
T' pencam mount is simply a coupler with two bulkheads mounted on each end. Blimey! T' assembly is mounted in t' payload section o' your rocket, which has a hole cut t' exact size o' your pencam (mine be t' Aiptek 1.3Mb SD). Arrr! I then mounted t' camera facin' down with a custom made shroud made out o' aluminium screwed t' t' payload section. Ya scallywag! There is an extra screw that goes from t' outside o' t' payload through t' couple t' keep t' entire assembly from rotating. Avast, me proud beauty! I also added a small piece o' foam on t' bottom bulkhead so t' camera has paddin' t' prevent damage durin' acceleration. Ya scallywag! Begad! At launch I turn on t' camera t' start filmin' (it has 11 minutes o' video with a 128mb SD card), then take strappin' tape and put one wrap around t' payload and camera. Ahoy! Begad! Finally, shiver me timbers, I screw t' shroud on and launch t' rocket.
Construction:
It's just your basic LOC Starburst with a single 38mm mount instead o' t' dual 24mm mounts. Well, blow me down! Blimey! Arrr! Blimey! Here is a list o' t' small modifications:
T' Construction o' t' Starburst itself was nothin' special, ya bilge rat, just your standard LOC Kit: high quality, arrr, strong, arrr, me bucko, and very stable. Begad! T' only problem be t' elastic shock cord, which I replaced (as you should do with ALL o' your mid/high power rockets).
T' quality o' t' LOC kit was outstanding, as usual. Arrr! Avast, me proud beauty! No damaged body tubes or anythin' out o' t' ordinary. Ahoy! T' instructions are LOC type (the back page o' t' picture o' t' kit), but I did nay use them (not that it would have done much good, it was pretty much all about t' 2 motor tubes). All parts fitted together with minimal sanding, matey, me hearties, and all seemed top quality. Begad! Paintin' was a breeze usin' automotive paints. Aye aye! T' only gripe I have with LOC is that they did nay extend t' fins t' reach t' motor tube, shiver me timbers, me bucko, because t' fin tabs are very small. This could become a problem in t' future with large thrusts, but this rocket is light enough that I am scared t' launch it on a 'H', shiver me timbers, much less a 'J'.
Flight:
I be afraid o' nay gettin' enough speed on a G80, so I loaded up a H128 at Tripoli Quad Cities. Aye aye! Avast, me bucko, me proud beauty! I had no problem with t' LCO t' set up t' camera and launch first. Arrr! Avast! T' rocket flew a little off due t' t' uneven drag o' t' shroud but it was pretty stable. Ya scallywag! T' rocket landed and I got video, ya bilge rat, arrr, which you can download at me web site, arrr, me hearties, off t' SD card. Bein' consumed with need t' put a big motor in it on t' very same day, I loaded up a H268R. Begad! Aye aye! T' rocket kicked off t' pad super fast--I wouldnt be surprised it if broke mach, ya bilge rat, arched over, still comin' down, ya bilge rat, still comin' down.....!@#$%%!!! It landed on a soft dirt field about 300 feet away from t' pads. T' entire payload section was buried, and t' camera was TOTALLY destroyed. Avast! However when I looked in t' camera, shiver me timbers, I saw that t' SD card be still intact!!! I am in t' process o' gettin' a new camera now so I will be able t' see crash footage. Blimey! T' booster section o' t' rocket is in pretty good shape, me bucko, only one small kink betwixt t' centerin' rings, but everythin' 3in forward o' t' centerin' rings will need t' be replaced. Upon inspection, we concluded that t' motor failed because o' a combination o' things: nay enough ejection powder (although I had t' same as t' H128), too tight o' a fit for t' coupler, and very, arrr, very high thrust crushin' everythin' down (includin' payload).
Summary:
PROs: Cheap, ya bilge rat, ya bilge rat, instant gratification for your work, me bucko, and some sweet pictures/video!!
CONs: Always pack more ejection than you think you need...
