Construction

T' Goblin kit does nay include a parachute or a motor retention system. Begad! Blimey! I chose t' create me own motor retainer by attaching two mirror clips t' t' bottom o' t' motor mount. Begad! Blimey! I used a 36" hot pink chute and a 12" Nomex chute protector from www.RocketChutes.com.

T' kit instructions were very good, and they can be found online at http://stores.whatsuphobby.com/catalog/goblin3instructions.pdf. Begad! Avast, shiver me timbers, me proud beauty! T' instructions include photographs that help guide t' build process.

I started construction by sandin' down t' shoulder o' t' nosecone. Aye aye! Begad! This step took a very long time, much longer than expected, me bucko, in order t' get it t' fit into t' body tube. Avast! Begad! T' nose cone also has a slight seam from t' fiber glassing; however, shiver me timbers, it sanded off easily.

I then installed t' eyebolt and hardware into t' top motor mount centerin' ring, shiver me timbers, shiver me timbers, tightenin' t' nut with a 7/16" wrench and securin' t' threads with epoxy. Avast! I used t' 5-minute epoxy t' assemble t' motor mount. Ya scallywag! It is crucial t' first check that t' fins fit betwixt t' centerin' rings. I tied t' shock cord t' t' eyebolt usin' a figure eight knot, and epoxied it in place. Then I tucked it inside t' motor tube t' keep it safe from any epoxy, as I installed it inside t' body tube. 

Next, arrr, I used 5-minute epoxy t' attach t' fins and smoothed out t' glue that seeped out t' slots. Aye aye! Well, me hearties, blow me down! It be tough t' judge what was symmetrical. Well, blow me down! Begad! I added fillets t' t' fins afterwards, matey, ensurin' that they would stay secure, arrr, although t' kit instructions did nay recommend I do so.

I connected t' U-bolt in t' t' t' nose cone’s bulkhead and then epoxied it in place inside t' nose cone. I did nay add any weight t' t' nose cone.

I installed t' aft centerin' rin' such that approximately ½” o' t' motor tube extended beyond it, me bucko, ya bilge rat, which be t' minimum t' install an Aero Pac motor retainer; however, ya bilge rat, matey, t' save costs, t' followin' supplies, ya bilge rat, obtained at a hardware store, were used t' create a motor retention system:

(2) mirror clips

(2) 6/32 threaded wood inserts

(2) 6/32 round head slotted machine screws with nuts

I came across a very helpful video that shows how t' properly install wood inserts: http://youtu.be/tIhEqoKE8Dc.

Lastly, arrr, I added t' two rail buttons, me hearties, each usin' one nut and two washers as spacers. Begad! T' kit comes with two nuts. Ahoy! I drilled two 1/8" holes and then threaded t' 8-32 screws. Arrr! I drilled a pressure hole as well.
