Brief:
My original Goblin clone (BT-55 based) be one o' t' first I built after really gettin' back into t' hobby.

My 1.7X upscale be finished late last year. Blimey! Blimey! And four months ago, matey, t' "baby" was born. Avast, me proud beauty! Blimey! It's a MMX powered, shiver me timbers, carded model. Well, blow me down! Blimey! It has a hand rolled ½" diameter body tube and triple laminated fins. Ya scallywag! Blimey! Avast! Blimey! All in total, three Goblins. Avast, me proud beauty! Blimey! Avast! Blimey! Finished, matey, flown and ready for family portraits.

For two extra points (2009 EMRR Challenge), me bucko, I needed t' add another member o' t' Goblin Family by t' October first deadline.

Construction:
This year, loot is tight. Avast, me proud beauty! I set a goal o' buildin' another model usin' just t' materials I had on hand. Aye aye! Ya scallywag! No ordering parts!

I had a ThunderGoon ready for final paint. It's been sittin' for months. Arrr! Ya scallywag! I just wasn't moved t' finish it. Blimey! Nice model but just nay for me. I decided t' cut off t' fins and body tube, ya bilge rat, salvagin' t' engine mount and nose cone. The engine hook was made from that metal strip from a windshield wiper blade. Begad! Begad! I remember t' look me youngest daughter gave me when I pulled it from t' trash can at an auto supply store. Arrr!

I found scrap BT-60 and cut it t' 8-½". Ya scallywag! T' ThunderGoon's nose cone was taller than a Mini Bertha's. It didn't matter, it'll still capture t' original feel.

I pulled some scrap 1/8" balsa and upscaled t' fins slightly from t' BT-55 dimensions. Well, blow me down! Arrr! I cut two o' the fins and realized I didn't have quite enough for other two. Avast! I didn't want t' cut into another full sheet o' balsa.

I started piecin' together scraps makin' sure t' grain be parallel. Blimey! I glued t' seams with CA, arrr, me bucko, then cut the remainin' two fins. Aye aye! This is when I started thinkin' o' t' "Frankenstein Goblin" moniker.

T' Keelhaul®©™® was already attached t' t' engine mount from t' Thundergoon. Begad! I pulled an 18" length o' elastic out o' me first attempt at a paper rocket. Ahoy! I've never flown that paper model or doubt I ever would. Well, blow me down! Begad! There was too many mistakes learnin' t' new paper cardin' techniques. Avast, me proud beauty!

T' 12" parachute was pulled from an old Groove Tube, a homemade garbage bag type. Arrr! For this rocket, me bucko, what else? I found a screw eye in me parts box. Ahoy! Avast! This eye is way too large but seemed t' fit t' theme and t' extra nose weight can't hurt.

There was nothin' unusual about t' build. Begad! Aye aye! It be a little different buildin' a new model from pieces and parts pulled from other models. Ya scallywag! Begad! If you include leftover balsa scraps, I estimate t' Franken Goblin was built with parts from six different models. Begad!

Finishing:
Originally, shiver me timbers, arrr, I be goin' t' use some Goblin decals from Excelsior. They were leftovers from me original BT-55 based clone. Aye aye! Phred always seems t' add extra images on t' master sheet. Begad!

I thought I would have some fun. I scanned t' Goblin decal sheet, ya bilge rat, enlarged it slightly then cleaned it up in Corel Draw. Well, blow me down! Blimey! Well, blow me down! Blimey! Blimey! Blimey! T' more I drew, ya bilge rat, arrr, t' stranger it got. Avast, me proud beauty! Blimey! Ya scallywag! Blimey! Blimey! Blimey! I drew t' word "Franken" tryin' t' emulate t' original hand drawn font. Begad! Blimey! Blimey! Blimey! I added Frankenstein "stitches" and neck bolts t' t' Goblin character. Begad! Blimey! Blimey! Blimey! T' Goblin even got a bad nose job. Blimey! Blimey! Sure, t' humor is a little inside, ya bilge rat, but still fun. Arrr! Blimey! Blimey! Blimey!

T' original plans show a decal "3" flipped on it's back, shiver me timbers, centered on both sides o' one fin. Avast! I decided to use a "6" instead. Ya scallywag! It's only two sixes, me hearties, almost three--almost evil. Well, blow me down! Ahoy!

O' course, ya bilge rat, I had t' go with a "Frankenstine" green and black motif. Begad! Blimey! Normally I use t' Walmart (cheap) spray paint for most primary colors but they didn't have a green I liked. Aye aye! Blimey! For this model I bought a can o' Rustoleum Key Lime Green, t' only new expense on this rocket.

I shot t' model with Grey primer and sanded smooth. Begad! I then followed with a white undercoat. Begad! I was pleasantly surprised by how well t' green Rustoleum spray paint covered. Ya scallywag! Arrr! It's t' old line o' "You get what you pay for." T' Rustoleum went on smartly with far fewer coats than t' Walmart brand usually requires.

T' decal sheets required 3 light coats o' clear acrylic. Well, blow me down! I had never made decals before and was prepared for the worst. Begad! I tested t' printed decal sheet usin' Microscale Liquid Decal Film applied with a foam brush. Avast, me proud beauty! Ahoy!

When I tried t' transfer t' Microscale treated decals, they didn't seem thick enough. Avast, me proud beauty! Arrr! Some o' t' black ink dissolved. Begad! I had much better luck with t' clear acrylic sprayed decals. Avast, me proud beauty! T' decals instructions did recommend spraying with clear acrylic.

While me homemade decal's "skin" is a little thicker than a decal that would come with a kit, shiver me timbers, matey, I was still very happy with t' results.

While placin' t' decals I noticed a mistake in construction. When building, shiver me timbers, I glued a salvaged one piece launch lug at t' center o' gravity with a C6-5 engine installed. Avast, me proud beauty! Blimey! T' lug is now in t' way o' t' thick black decal band above t' fins. Begad! Blimey! I had t' pre-cut a "notch" in t' decal wrap t' fit around t' bottom o' t' lug. Avast, me proud beauty! Blimey! Another "Frankenstin" puzzle piece, cut and joined together. T' original Goblin instructions had you cut t' lug in two. Half at t' top, shiver me timbers, half at t' bottom o' t' body tube.

Flight and Recovery:
I flew t' Franken Goblin three times on March 7, 2009, me bucko, at t' monthly R.O.C.K. Avast! section launch.

T' first flight was with an A8-3. Begad! Well, matey, blow me down! I called for a heads-up. Sometimes "Gooney-fying" a classic leads to questionable stability. Well, matey, blow me down! It flew straight and true. Begad! Nay high but stable. Ya scallywag! Well, blow me down! T' 12" chute ejected fine.

T' next two flights were with B6-4s. Begad! Avast! Blimey! T' wind be comin' up so I cut a spill hole in t' 12" parachute. This seems t' be t' ideal engine for this model, me bucko, providin' good performance and altitude. Begad! Ahoy! Blimey! On t' third flight it was loaded on t' rack, shiver me timbers, me bucko, shiver me timbers, side by side with it's smallest sibling, me bucko, me MMX carded Goblin.

After three flights, thar were two small body tube dings in t' nose cone. Begad! Avast, me proud beauty! Both were nay very deep.

I know this model will be a regular flier in me fleet. Blimey! It's stubby (I like stubby models) and personalized. Blimey! Some of t' older fliers remembered t' Goblin and liked t' variation on t' original theme.

Summary:
PROS: I know this model will be a regular flier in me fleet. Begad! Avast, me proud beauty! It's stubby (I like stubby models) and personalized. Some o' t' older fliers remembered t' Goblin and liked t' variation on t' original theme.

CONS: None really.
