Modifications:
I had t' buy a scroll saw just t' do t' centerin' rings. Ahoy! I started with 54mm t' 7.6" rings and butchered them from there. Well, blow me down! I also had t' buy a jig saw and abrasive saber-saw blades that were designed t' cut tile. This be used t' cut t' massive notched G10 fins. Don't try t' learn t' fiberglass on tiny kits, ya bilge rat, matey, nor one this big. Avast! Begad! Go medium like an EZI or similar kit. I did it and it came out perfectly, but I think that I was just lucky. Avast, me proud beauty! Use premium epoxy as t' life o' t' rocket is at stake!
Construction:
Base airframe is unchanged from t' stock LOC Bruiser. I decided t' loose t' ridiculously small fins with massive ~14" X ~20" 50's style curved fins out o' G-10. Arrr! T' motor/fin assembly be built and stressed outside o' t' airframe and then secured into t' pre-slotted airframe. Ahoy! I also cut t' airframe t' just accommodate t' full 98mm motor mount. This allowed for positive anti-zipper. Well, blow me down! I reinforced t' airframe with 2 extra coupler tubes t' give me a backin' for two external electronics access doors. Ahoy! T' one in t' booster will house timer for air-startin' 6 outboard 29mm motors. Aye aye! Ahoy! T' payload access door allows for access t' custom altimeter bay. Blimey! I also used a 1.125" ID plastic gas pipe for t' launch lug. Avast, me proud beauty! I also installed drywall butterfly anchors for 3 launch lugs for Black-Sky rails.
T' rocket kit was well packaged and complete. Ahoy! Begad! T' paper tubes were good quality and would probably hold up t' J power without modifications. Aye aye! Ahoy! (Not Me). Avast, me proud beauty! Ahoy! There were minimal instructions as expected with an advanced kit. Avast, arrr, me proud beauty! There was a fin alignment page and construction detail sheet.
I made a big mistake while finishin' this rocket! Blimey! Screwed up a PERFECT fiberglass job, me bucko, and here is how I did it: 1) Filled t' FiberGlass dimples with bondo (good idea) 2) Found most beautiful wrappin' paper that shimmered (good idea) 3) Rolled on a thick coat o' epoxy (good idea) 4) Smoothed t' wrappin' paper onto t' tubes (bad idea) T' next mornin' when I got up t' go into t' garage and view t' most awesome holographic finish! Blimey! I sat and held back t' tears! Blimey! T' damn paper had buckled and partially separated from t' backing. Well, blow me down! Blimey! Well, blow me down! Blimey! Obviously t' holographic material had become separated from t' white paper backin' and then stretched slightly. Looked like underwear with terribly worn out elastic. My heart was hurtin' and only 9 days from launch! Blimey! I ran out and purchased an orbital sander and went through 30 full sheets o' coarse (expensive too) sand paper. Arrr! Blimey! Five days later I had what could be called an Earl Schribe base for a paint job. Begad! Blimey! I could nay get all o' t' epoxy ridges and valleys off. Avast, me proud beauty! Blimey! Ya scallywag! Blimey! I just painted it t' best that I could. Avast, me bucko, me proud beauty! Blimey! I think that it came out pretty good, matey, ya bilge rat, considerin' what I went through!
Flight:
Recommended motors with t' kit were big "I" t' big "J". But that be THEIR kit, and this was MINE! A 54mm K-550 was t' only choice in me head. Avast! Sim'ed out at 2000'. Arrr! Avast, me proud beauty! Plenty o' room for our 5000' waiver. Ahoy! When I built t' fin/motor unit, arrr, I planned ahead (this time) and put in 3 each 1/4-20 "T" nuts and epoxied them well on t' inside for positive motor retention ability. Avast! T' adapter (54 t' 98) that I built was short o' t' motor casing. Ya scallywag! This allowed me t' tape t' adapter t' t' motor casin' where t' casin' protruded about 6" above t' adapter motor mount tubing. Then 3 each 1/4-20 bolts and a couple o' fender washers took care o' t' rest.
I custom built t' two shock cords. Blimey! Both 1"x50' fluorescent nylon webbing. Begad! I sewed in a "Y" attachment point and used steel lockin' d-rings for attachment. I could smartly take t' whole thin' apart in a matter o' seconds and put it back together in t' same. I know, ya bilge rat, because I had t' double-check t' locks.
T' launch be absolutely perfect. Blimey! Nay too slow and nay too fast. Well, shiver me timbers, blow me down! Lots-o-noise and wonderful smoke shroom! Did nay spin or even rotate, shiver me timbers, arrr, straight up. Aye aye! At just below apogee, shiver me timbers, t' RRC2 controller popped me homemade ejection charge and t' 6' drogue opened perfectly! At 500' t' main charge popped and ejected t' 10' main. It was picture perfect; a HUGE chute that took about 100' and 5 seconds for t' main t' fill completely, but it felt like 20 minutes! She landed upright and almost stayed that way. I could have launched again in t' time t' reload. Begad! Blimey! Nay a scratch!
Summary:
T' small fins o' t' original kit are just too small. I think that it takes away from t' overall awesomeness o' this kit. This is a most perfect modification kit and/or easy level II. Begad! Blimey! Well, matey, blow me down! Blimey! I have and will recommend t' LOC Bruiser t' one and all!
This kit really taught me about buildin' rockets from scratch. Begad! Ya scallywag! I know that doesn't make any sense, ya bilge rat, shiver me timbers, me bucko, but think about it. Blimey! Blimey! I spent TONS o' time examinin' and redesignin' somethin' that I KNEW was already well tested. Arrr! Avast! I could concentrate on me talents and forget about t' other things. Avast, me proud beauty! Begad! Then I had t' take into account t' original kit design t' learn how me mods had effected it. Begad! Good method. Avast! I will mod a lot more (and REAL soon).
