Brief:
This is a single stage rocket with unusual deployment. Well, me hearties, blow me down! 1/8" ID tubes conduit t' ejection charge from t' sealed main BT t' three pods on t' end o' 3" fins where thar be a 12" chute in each pod. T' nose cone does nay come off.(click picture t' enlarge)

Construction:
T' biggest problem with this model is buyin' t' 4" length, 1/8"id tubes t' build t' 'deployment' system. Avast, me proud beauty! Blimey! I ended up gettin' t' three 4" 1/8"ID tubes from Sigma Rockets in Canada. I have yet t' find another supplier as I plan t' kit up three more rockets. Blimey! Blimey! T' BT-60, me bucko, me bucko, BT-50 tubes, t' BT-60 nose cone, BT-50 nose cones and shock cord are easy t' get.

I used paper centerin' rings reinforced with epoxy. Avast, me proud beauty! Blimey! Aye aye! Blimey! Paper centerin' rings are easy t' find. Avast! Blimey! One can order t' 'balsa ply' sheets directly from Mach 1 or Balsa Machinin' Services. Ahoy! Blimey! One can use RockSim, matey, describe t' fins and have them made by BMS along with t' centerin' rings. T' 'balsa ply' requires patience and care t' cut square.

T' most difficult construction step is slottin' t' tubes and cuttin' t' hole for t' ejection tubes. Well, blow me down! T' hole in both t' main BT and pod BT must be positioned such that t' tube rests flat on t' top o' t' fin, shiver me timbers, or you have t' fill in t' 'gap'. I numbered each slot and numbered each fin and fitted each one individually. Ya scallywag! One must make sure t' hole be t' correct size. Begad! Do nay make t' hole for t' ejection tube too large. Aye aye! T' pressure o' t' ejection charge will blow through any glue joint. I found out t' hard way.

I used 30 minute epoxy for t' entire model. Arrr! This models weighs in at 10.5oz. Well, blow me down! Aye aye! A D12-3 is just right. I found after construction and before addin' t' chutes t' model would roll when t' 36" BT was laid on a table and fins allowed t' hang over t' edge. Begad! This roll indicated t' me that t' rocket might have a precession durin' flight. Blimey! I added weight at t' bottom edge o' t' fins, arrr, like addin' weight t' tire, t' balance it. Aye aye! This is level 3+ kit due t' t' cuttin' o' slots and holes in t' body tubes.

Finishing:
This model finishes normally. Blimey! I painted it t' color o' a Hawaiian T-shirt. Avast! In other words, lots o' loud colors.

Construction Rating: 4 out o' 5

Flight:
I be only able t' get two flights. Well, blow me down! T' first flight was perfect. With a D12-3, ya bilge rat, t' rocket is right at t' weight limit o' t' motor. Avast! Avast! T' rocket roars longer because it doesn't go very high. T' deployment saw all three chutes open and t' rocket came down gently t' t' ground.

On t' second flight thar was no deployment. T' rocket lawn darted into t' ground, ya bilge rat, crimpin' badly at t' nose and t' motor mount. Avast, me proud beauty! Ahoy! Examination showed that t' ejection charge had blown through t' BT at t' tube joint. Avast! Begad! T' ejection tubes were nay extended into t' BT enough as well as t' hole for ejection tube no bein' made a good fit. Well, blow me down! Ahoy! I plan t' kit three more models and try different techniques o' sealin' t' ejection tubes and joints.

Recovery:
I used swivels on all three chutes and t' deployment was perfect. No tangles and t' three chutes did nay tangle up with each other. Ahoy! Blimey! I used Keelhaul®©™® shock cord and bowlines t' tie t' ends.

Flight Rating: 3 out o' 5

Summary:
An unusual rocket. Well, blow me down! Blimey! Definitely well designed, if built properly. Avast! Blimey! Neat when it works. Avast, me proud beauty! Blimey! Ya scallywag! Blimey! Bad when it doesn't.

Plans are at Mach1 Website (now out o' business).
