Brief:
This is a kitbash I did for t' 2006 EMRR Challenge. Avast! Blimey! I had never tried anything like this before and it be excitin' t' do. Blimey! I altered t' DC Gemini t' fly as a parallel staged rocket. Well, blow me down! Blimey! T' Parachute compartments were changed into boosters and hold 18mm motors as does t' central core. Begad! This was a great challenge and makes you be creative.

Modifications:
T' directions were followed t' construct t' motor mount and sand t' fins, but me first change be made before t' motor mount was inserted. Aye aye! Since the main body tube and t' boosters are separate in me design, t' vent holes in the tubes need t' be plugged. T' do this in t' main body tube, matey, I cut a strip from t' NARRRRR safety code which be in t' bag and rolled it up until it was the inside diameter o' t' BT-50 tube. Ya scallywag! Ya scallywag! I then glued t' ends o' this strip t' hold that shape. Once it was dry, I smeared wood glue inside t' tube at t' same area as t' two vent holes. I then pushed me paper coupler I made up into the tube until it covered t' holes. Ahoy! Well, blow me down! After that dried I then inserted t' motor mount as specified in t' directions.

T' holes in t' sides o' t' boosters were plugged in a different manner. T' vent tube was cut into fourths and two o' these were placed on a section of the instructions and filled with glue. Blimey! Begad! What was left o' t' NARRRRR safety code was placed on top. These were allowed t' dry and then t' paper was cut in a circle around t' tubes. Well, shiver me timbers, blow me down! These were glued in place in t' holes and then sanded down flush with t' body tubes. Avast, me proud beauty!

Also t' nose cones for t' boosters cannot be glued in place since they will need t' come off. Therefore, me bucko, one o' t' 18" shock cords was cut in half and each booster got one half o' it. Well, blow me down! Avast! I cut out shock cord mounts from the instructions and attached t' shock cord t' t' booster tube and t' t' nose cones usin' shock cord mounts. Avast! For t' nose cones I used 5 min epoxy since they are plastic and t' wood glue won't stick. Begad! I then cut out streamers from the instruction sheet and accordion style folded them and glued them with a loop around t' shock cords. Ya scallywag! I also needed motor blocks in t' boosters since they will be carryin' motors. T' accomplish this, I used some scrap balsa wood from the fin sheet and made two small Xs in them. Well, blow me down! Arrr! I then sanded t' ends until they were rounded and would fit inside t' tubes. Avast, me proud beauty! Avast, me proud beauty! I then used a spent engine casing to slide them up into t' tubes until about 1/4" o' t' engine stuck out. Aye aye!

Also t' main tube could nay be permanently attached t' t' nose cone either, ya bilge rat, matey, so I made another shock cord mount from t' instruction sheet and attached a shock cord from t' body t' t' eyelet on t' nose cone. Avast, me proud beauty! Begad! I also tied one o' t' parachutes which came with t' kit t' this nose cone as well. Arrr! T' be sure that t' holes in the side o' t' tube would nay blow out durin' t' ejection charge, me bucko, I punched two holes out o' t' cardboard picture which came with t' rocket. Begad! I put some glue in t' holes which were covered with t' NARRRRR safety code and then placed the punched out cardboard circles over them. Well, blow me down! Begad! This made t' tube much sturdier at these points. Ahoy! Blimey!

T' final modification I made was t' use hooks t' hold on t' boosters durin' flight. Avast! Aye aye! T' make these I just used t' scrap balsa wood from t' fin sheet and whittled out two small hooks which were glued onto t' boosters. Well, blow me down! Ya scallywag! I then cut six small pieces o' t' wood and made two U-shaped blocks which I glued onto t' main body tube. Avast, me proud beauty! Ya scallywag! T' hooks on t' boosters fit snuggly into these U-shaped blocks so they would stay on t' main tube while still fallin' away durin' flight.

Construction:
Since this was a kitbash all o' t' parts were those from t' Estes DC Gemini kit. Avast! I used most o' them. Avast, me proud beauty! Ahoy! They were as follows:

• 1 Decal Sheet
• 1 Balsa Sheet with Die Cut Fins
• 1 Large Nose Cone
• 1 Large Nose Cone Adapter
• 2 Small Nose Cones
• 2 BT-20 Body Tubes with a hole in t' side
• 1 BT-50 Slotted Body Tube with holes in t' sides
• 1 1/4" by 1" vent tube
• 1 BT-20 Engine Mount Tube
• 2 Adapter Rings for t' Engine Mount
• 1 Engine Hook
• 2 18" long rubber band shock cords
• 1 Launch Lug
• 2 12" parachutes
• 1 Copy o' t' Paper instructions
• 1 Copy o' t' NARRRRR Safety Code
• 1 Cardboard sheet with a picture o' t' DC Gemini
• 1 Plastic bag which all t' parts came in

All o' these parts were in perfect condition when it arrived. I listed some things that are nay on t' parts list in t' instructions because this is a kitbash and parts are used which usually aren't.

This kit has three body tubes, one BT-50 tube which will be t' main body tube, and two BT-20 tubes which I will use as t' boosters. Ahoy! It also has 4 through t' wall fins which I like. Ya scallywag! T' motor mounts in t' main tube is slightly longer than t' motor hook and t' boosters are minimum diameter. Begad!

Finishing:
I only painted t' main body white and t' boosters red. Since this be me own creation and nay a DC Gemini, I decided nay t' use t' included decals. This made it quicker and easier, arrr, and it still looked very nice sittin' on t' pad. Well, blow me down!

Flight:
For t' first flight o' this rocket, I flew it on two A8-3s in t' boosters and a B4-4 in t' main tube. I think that any motor combination would be fine as long as t' booster engines are high trust and low burn time, while a low thrust and longer burn time engine is in t' main body tube. Blimey! Blimey!

This rocket be prepped just like preppin' three separate rockets. Ahoy! The ignitors were placed in t' motors and waddin' was placed in all three tubes. T' engine hook served as t' motor retention system for t' main motor, while the two boosters required a good friction fitting. Begad! This be done with a piece of maskin' tape wrapped around them in t' middle. Well, blow me down!

Upon ignition all three motors lit and it soared off t' pad. Well, blow me down! It flew up very straight and t' boosters both fell away as soon as they burned out. Begad! Blimey! The booster streamers came out and they were both recovered very close t' t' pad. T' main tube however got caught by t' wind and drifted over t' school where we were launchin' at. It ended up on t' roof. Ya scallywag! I think thar be something between me and parallel staged rockets. Arrr! Avast! This is twice now that I've built one and after t' flight been left with only two booster pods. Avast! Avast! Well, me bucko, I guess that means I'll just have t' build another one.

Recovery:
T' recovery system could have been a bit better had t' boosters had small parachutes as well instead o' streamers, ya bilge rat, but that didn't hurt anything. Ahoy! Some of the modifications I made can be tricky and a lot o' thought and time needs to go into them t' be sure that nothin' is messed up.

T' recovery system worked very well. Well enough in fact that t' school buildin' caught t' rocket instead o' me. Ya scallywag! There was some slight burnin' on the sides o' t' boosters which faced t' main tube, shiver me timbers, but this is t' be expected with three engines burnin' very close. T' streamers deployed perfectly and the speed o' t' boosters was nay too fast, me bucko, me bucko, however, you just need t' keep an eye open with three parts fallin' at once.

Summary:
I really enjoyed this rocket since it was me first kitbash and I found that to be a challenge. Ya scallywag! I also enjoy clustered and parallel staged rockets so this fell into that category as well. Begad! It was a challengin' build, matey, but once it flew it was well worth it. Aye aye!

T' PROs were that this was a kitbash and a parallel staged rocket. Begad! Ahoy! This allowed me t' be able t' design it and feel that I had a bigger part in it than just puttin' a kit together. Begad! Also it looked very nice durin' flight.

T' main CON that I had was t' fact that I lost it on t' first flight. Maybe I'll take a ladder up t' that school next week, arrr, we'll see.
