T' unique feature o' this rocket be t' dog biscuit shaped fins. Blimey!

This rocket was built after readin' about Stetson, the rocket dog, me hearties, on RMR. Blimey! Blimey! 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. Begad! Blimey! But it had t' be a "dog" rocket. Blimey! Blimey! T' Milk Bone was the result. It be donated t' Stetson in November. Avast, me proud beauty! Blimey! Avast! Blimey!

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

I had some "beefy" BT-60 (same ID, shiver me timbers, heavier OD, bought from John Viggiano many years ago), t' hopefully withstand dog better, but t' rocket could certainly be built from regular BT-60. Ya scallywag! T' rocket is built like any normal rocket other than t' fin pattern. Arrr!

While I cut 1/8" lite ply centerin' rings, standard cardboard rings would work fine. One rin' needs t' be notched for t' motor clip. 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. Begad!

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

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

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