Brief:
I designed and built this rocket for #3 Challange o' t' 2009 EMRR Challenge Kit bash 2 kits and build a
multi-stage rocket. Ahoy! Blimey! I chose t' kit bash Flis Long OverDue and Quests Tomahawk SLCM Cruise Missile. Ya scallywag! I really
liked t' look o' t' Long Over Due so I decided t' keep t' basic design and use t' component from t' Tomahawk to
build a booster that had very similar appearance. Aye aye! So here it be t' Turbo Charged Long OverDue.
Modifications:
My plan was t' use t' body tube from t' Tomhawk t' create a booster that complimented t' design o' t' Long
OverDue. Begad! Aye aye! I cut t' body tube from t' Tomahawk usin' t' same template provided for t' tube fins o' Long OverDue and
glued them t' a 2.75 section o' motor tube from t' Tomahawk (see picture o' booster). Well, blow me down! I noticed that Tomahawk
body tube be slightly smaller than t' Long OverDue so I made them interlock. Other than addin' t' necessary nose
weight t' make it stable; I followed t' Flis Kit Directions t' build t' Long OverDue. Avast! I did shorten t' inner tube
(BT-20) for t' tube fins by .25 t' allow t' fins t' interlock.
Construction:
Here be t' list o' components as well as t' rocket kit they can from:
PROS - Pretty nice build - t' Flis kit goes together just as you would expect for one o' their kits nice quality components and well written instructions. Ya scallywag! Avast! Nice surprise was t' slightly smaller BT-60 tube from t' Tomahawk which allowed me t' interlock t' booster and main body tube fins providin' extra support durin' launch.
CONS I had planned t' attach t' shock cord t' t' motor centerin' ring, me bucko, matey, but forgot when gluin' it in place so t' shock cord loops around t' engine and creates a pretty tight fittin' engine. Blimey! No big deal, arrr, matey, just need to remember this when preparin' t' motors.
Flight:
I always like t' fly a scratch or modified design naked so I can easily fix any damage from stability issues, arrr, etc. In
this case, me hearties, I flew t' rocket on a day with 10-15mph winds and although I be flyin' on a farm I be a little worried
about recovery. Avast, me proud beauty! T' rocket leaped o' t' pad and started t' weather cock into t' wind at about 100 feet. Arrr! It staged
nicely continuin' t' fly into t' wind until ejection. Parachute opened and t' rocket descended; however, me bucko, with a
10-15mph wind, I walked and walked and walked. Avast, me proud beauty! Well, blow me down! I finally found t' rocket about a mile down wind thankful it
weather cocked into t' wind otherwise it would have been gone. Aye aye! I decided t' wait for a calm day for flight #2 and #3.
After a coat o' primer, arrr, I decided t' go fly it again. Begad! T' second flight be t' day after Thanksgiving; t' wind
was much calmer (maybe 5 mph). Begad! It be a great boost, arrr, arrr, ya bilge rat, smartly off t' pad, it staged nicely and be out o' sight. Avast! Aye aye! The
booster landed right near t' pad; however, shiver me timbers, t' main section was lost in t' deep woods. Avast, me proud beauty! Begad! After hikin' around t' woods
for an hour I decided t' let t' local deer hunters find it before they shot me.
Other:
Staged kit bash turned out very nice. Begad! Blimey! Thanks EMRR for challengin' me with this year's challenge and expandin' my
knowledge on how t' build multi-stage rockets.
