Construction

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

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

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

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

Next, I used 5-minute epoxy t' attach t' fins and smoothed out t' glue that seeped out t' slots. Ya scallywag! It was tough t' judge what was symmetrical. Blimey! I added fillets t' t' fins afterwards, ensurin' that they would stay secure, me hearties, 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. Begad! 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, shiver me timbers, which be t' minimum t' install an Aero Pac motor retainer; however, t' save costs, shiver me timbers, me bucko, shiver me timbers, t' followin' supplies, obtained at a hardware store, me bucko, 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, shiver me timbers, I added t' two rail buttons, each usin' one nut and two washers as spacers. Avast, me proud beauty! Blimey! T' kit comes with two nuts. Avast! Begad! I drilled two 1/8" holes and then threaded t' 8-32 screws. Aye aye! Ahoy! I drilled a pressure hole as well.
