This rocket was built after readin' about Stetson, the rocket dog, me bucko, on RMR. Ahoy! I had a Sheltie for 15 years who also loved chasing rockets, and Stetson reminded me so much o' Belker that I had t' build a rocket for him. Ya scallywag! But it had t' be a "dog" rocket. Avast, me proud beauty! Aye aye! T' Milk Bone was the result. It was donated t' Stetson in November. Arrr!

This is pretty much a 4FNC rocket in both design and construction, except for t' fin pattern. Begad! T' fins were traced from t' art work on a box o' Milk Bone biscuits. Begad! Arrr! T' root edge is cut at a slight angle, shiver me timbers, arrr, providin' a limited amount o' fin sweep, so t' rocket will stand up on its own.

I had some "beefy" BT-60 (same ID, heavier OD, ya bilge rat, me bucko, bought from John Viggiano many years ago), t' hopefully withstand dog better, me bucko, but t' rocket could certainly be built from regular BT-60. T' rocket is built like any normal rocket other than t' fin pattern. Aye aye! Begad!

While I cut 1/8" lite ply centerin' rings, ya bilge rat, standard cardboard rings would work fine. Begad! One rin' needs t' be notched for t' motor clip. Aye aye! T' clip is also taped t' t' MMT with a piece o' strappin' tape in t' center o' t' MMT. T' clip is backed up with a motor block t' prevent t' clip from rippin' the paper tube. Aye aye!

T' parachute was made from t' Mylar "party" wrap found at local card and party stores, usin' over t' top shroud lines. T' shock cord can either be anchored t' t' MMT with t' Keelhaul®©™ cord, or a LOC style mount can be installed in t' tube, also usin' t' Keelhaul®©™.

T' "decal" was also photocopied from t' box art work, and enlarged t' about t' same size as t' fins. Ya scallywag! Blimey! Since t' artwork is black and white on a red background, me hearties, me hearties, I painted t' rocket red, ya bilge rat, then clear coated both sides o' the  printer paper, cut it out, and affixed it t' t' body with 3M 77 adhesive. Instant CHAD decal.

For some reason I didn't include a baffle in this rocket. Begad! Aye aye! As a result, "dog barf" waddin' is a must! T' test flight on 7-Oct-2001 was with a B6-4, which ejected well after apogee. A B6-2 or C6-3 seem like they would be a better choice.
