Construction

T' Goblin kit does nay include a parachute or a motor retention system. Begad! I chose t' create me own motor retainer by attaching two mirror clips t' t' bottom o' t' motor mount. Avast, me proud beauty! Aye aye! 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. T' instructions include photographs that help guide t' build process.

I started construction by sandin' down t' shoulder o' t' nosecone. This step took a very long time, me bucko, arrr, much longer than expected, in order t' get it t' fit into t' body tube. Begad! 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, me hearties, 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. 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, 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. Begad! Blimey! Avast, me hearties, me proud beauty! Blimey! It be tough t' judge what be symmetrical. Avast! Blimey! Blimey! Blimey! I added fillets t' t' fins afterwards, ensurin' that they would stay secure, 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. Blimey! 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, which be t' minimum t' install an Aero Pac motor retainer; however, arrr, t' save costs, t' followin' supplies, 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, I added t' two rail buttons, each usin' one nut and two washers as spacers. T' kit comes with two nuts. Avast, me proud beauty! I drilled two 1/8" holes and then threaded t' 8-32 screws. Well, blow me down! I drilled a pressure hole as well.
