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