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