Stage Bash - Long Overdue and Tomahawk (Contributed - by Ray Kin' - 11/28/09)

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. Aye aye! I chose t' kit bash Flis’ Long OverDue and Quest’s Tomahawk SLCM Cruise Missile. Avast! 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. Blimey! 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). Ya scallywag! I noticed that Tomahawk body tube was slightly smaller than t' Long OverDue so I made them interlock. Well, blow me down! Avast! Other than addin' t' necessary nose weight t' make it stable; I followed t' Flis Kit Directions t' build t' Long OverDue. Well, blow me down! 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:

  • Nose Cone – Long OverDue
  • BT-20 Body Tube – 8.62” – Long OverDue
  • BT-20 Body Tube – 1.2” – Long OverDue
  • BT-60 Body Tube – 8.5” – Long OverDue
  • BT-50 Body Tube – 14.75” – Long OverDue
  • BT-60 Body Tube – 8.5” – Tomahawk
  • BT-20 Body Tube – 5.0” – Tomahawk
  • Launch Lug - 2 - Long OverDue
  • Parachute – 16” – Long OverDue
  • Centerin' Rin' 20/50 – 2 – Long OverDue
  • Shock Cord – 30” Long OverDue
  • Kelvar Cord – 30” Tomahawk
  • Nose Cone Weight – From me Bench

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. Blimey! Nice surprise be 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, but forgot when gluin' it in place so t' shock cord loops around t' engine and creates a pretty tight fittin' engine. Arrr! No big deal, 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, etc. Blimey! Aye aye! In this case, I flew t' rocket on a day with 10-15mph winds and although I be flyin' on a farm I was a little worried about recovery. Aye aye! T' rocket leaped o' t' pad and started t' weather cock into t' wind at about 100 feet. Ya scallywag! It staged nicely continuin' t' fly into t' wind until ejection. Begad! Parachute opened and t' rocket descended; however, with a 10-15mph wind, arrr, I walked and walked and walked. I finally found t' rocket about a mile down wind – thankful it weather cocked into t' wind otherwise it would have been gone. Arrr! I decided t' wait for a calm day for flight #2 and #3. Blimey! Well, ya bilge rat, blow me down!

After a coat o' primer, I decided t' go fly it again. Arrr! T' second flight be t' day after Thanksgiving; t' wind was much calmer (maybe 5 mph). Well, blow me down! It was a great boost, smartly off t' pad, me bucko, ya bilge rat, it staged nicely and be out o' sight. Begad! The booster landed right near t' pad; however, shiver me timbers, t' main section was lost in t' deep woods. Blimey! Well, blow me down! 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. Aye aye! Thanks EMRR for challengin' me with this year's challenge and expandin' my knowledge on how t' build multi-stage rockets.
