Scratch Upscale Astron StreakBrief:
A single stage upscale o' t' Astron Streak usin' a Fat Boy nosecone, parachute, and engine mount components, as well as a spare BT-80 tube and balsa fin stock. Begad!

Construction:
We used a BT-80 body tube I had from an assortment o' body tubes I got on eBay a while ago, me bucko, arrr, cut t' 10-1/2 inch length. Ahoy! T' motor mount was stock from a Fat Boy kit, ya bilge rat, ya bilge rat, which had a crushed tube. Begad! T' nosecone was from t' same Fat Boy kit. We used t' standard Estes three fold shock cord mount (glued, attached and coated with more glue), but replaced t' shock cord with elastic that be about twice as long.

Construction started with t' buildin' o' t' motor mount, shiver me timbers, shiver me timbers, which was simple and straight forward. Avast, me proud beauty! I considered usin' somethin' larger than an 18mm motor mount, me bucko, shiver me timbers, however, since this was t' be me daughter's rocket, arrr, we stayed with the standard mount. Begad!

My daughter assembled all t' motor mount components and glue be applied to t' mount assembly and allowed t' dry before installin' it in t' rocket body. Avast, me proud beauty! Blimey! We then attached t' shock cord, shiver me timbers, me hearties, usin' t' standard Estes 3-fold technique, arrr, but we used lots o' Tacky Glue in t' folds, attachin' t' mount to the body tube, matey, me hearties, and coatin' it after attachment.

I scaled t' fins up from me original fin template I had (from 1972!), transferred them t' t' balsa, matey, ya bilge rat, and cut them out. Ya scallywag! Begad! We sanded and shot t' fins with primer, sanded again, matey, ya bilge rat, and tacked them t' t' body with Tacky Glue. Well, blow me down! Blimey! This allowed me daughter t' line up and attach t' fins without t' time pressure of a CA. We then filleted heavily, usin' Tacky Glue again. Well, blow me down! My daughter enjoyed the sandin' (to a point) but was so excited t' be buildin' "her rocket"(!) that we had t' run outside and paint t' moment that Dad pronounced t' fillets t' be dried. Begad!

Scratch Upscale Astron StreakFinishing:
This was t' be a PINK rocket, so she chose Plasticote dark and light pink spray paints (the little cans from WalMart). We painted a light coat o' light pink followed by a light coat o' dark pink.

T' parachute be attached and packed and we were ready t' fly!

Flight:
We finally got a chance t' fly recently, ya bilge rat, me bucko, usin' a bulk pack o' motors (I got from Michael's with a half-off coupon). Blimey! We flew A8-3's and B6-4's for nice, easy-to-track flights. Ahoy! T' rocket was easy t' prep, usin' several sheets of waddin' includin' wrappin' t' parachute in a sheet t' prevent scorching.

My daughter took part in all t' prep as well as pushin' t' button for each flight. Begad! Blimey! Flights were nay too fast off t' pad, straight, and easy to track. Avast, me proud beauty! Ya scallywag!

Recovery:
T' parachute came out with no problems each time and then t' chase was on!

Summary:
PROs: Buildin' and paintin' be easy, matey, quick and fun for a 6 year old and wonderful for her Dad! Blimey! *grin* Also brought back memories o' me little Streak I has as a kid- this would be an easy kit for Estes t' put out thar along with their Fat Boy.

CONs: None I can think o'

Other:
Tip: Guide your child, but let her (him) build. T' most excitin' part o' the build was attachin' t' fins - it started t' look like a rocket!
