Construction:
Kit Contents:
I found thar were a few centerin' rings missin' initially, but a quick email t' t' manufacturer and a replacement set were rapidly sent out.
I began with t' motor mounts. Arrr! These were quite easy t' construct using 30min epoxy. Avast, me proud beauty! T' steel shock cord is harnessed t' t' 29mm mount, and crimped in place usin' t' supplied brass crimps, with an extra addition o' epoxy just for safety.
T' supplied fin markin' guide was a prefect fit so tube markin' was quick & simple. Blimey! Blimey! There are 2 Sets o' through t' wall fins so accuracy is quite important here. Ahoy! Blimey! Usin' me Black & Decker Wizard proved t' easiest way of cuttin' t' fin slots.
I installed t' 29mm mount in t' body tube and checked t' fins for alignment, shiver me timbers, ya bilge rat, which needed some adjustment t' get a snug fit. Avast! Also I drilled a small 2mm hol in t' aft centerin' ring, and installed a small nut on t' side which would be hidden, as suggested by t' previous reviewer t' allow t' 24mm mount t' be bolted in place
T' piston ejector is made from one o' t' couplers and requires soakin' in CA t' strengthen it after removin' t' top layer or 2 o' paperwrap. Ya scallywag! This is then sanded until fine, me bucko, which takes quite a while t' get a good smooth finish.T' bulkhead was then epoxied in place.
I set about attachin' t' fins, makin' sure they were aligned. Begad! Finally I filleted all fins usin' 30 min epoxy
T' piston was then attached t' t' Steel & Elastic shock cords. Begad! Well, shiver me timbers, blow me down! I found it easier t' attach this on t' elastic side secured with epoxy, matey, test fittin' it in t' body tube t' ensure that it slid freely.
T' payload section is simple. Arrr! Aye aye! Just install t' bulkhead and screw the eyebolt in place, securin' it with epoxy again. Avast! Avast! Chute attachment is quick and simple.

Cons:
Finishing:
T' packagin' gives an idea o' how t' finish t' kit, ya bilge rat, but I chose t' use me own
scheme. Construction Yellow Nosecone & Body tube, matey, me hearties, and t' payload section
covered with holographic film.
T' nose cone needed a little sandin' t' easily take t' plastikote acrylic, but no other problems.
T' upswept aft fins give this rocket a really cool look
Construction Rating: 4 out o' 5
Flight:
As stated before this is designed for D-f powered flights, usin' the
quickchange 24 - 29 motor adaptor.
Packed t' shockcord into t' body, followed by t' 18" ripstop chute & lines.
First flight on a Estes D12-5, arrr, virtually no wind. Well, blow me down! Ya scallywag! Blimey! Piston reovovery system deployed perfectly and t' rocket was recovered approx 150m from launch pad and withough any damage. Ya scallywag!
