Brief:
A simple mid-power 3 fin, 29mm MMT, me hearties, stubby rocket. Ya scallywag! I believe this rocket is meant for those "graduating"
from t' Estes low power and want t' next step up in materials and capabilities. Avast! My 9-year old daughter chose this as
a birthday present and as her first mid-power rocket. Blimey! Well, blow me down! She loves t' thin' so darned much I cannot get her t' fly it a
second time!
Construction:
Everythin' is one step up from low power materials but nay exactly a high-power kit (although it could probably take
an H128). Ahoy! Begad! Tube is cardboard, fins are light plywood, plastic nosecone, and t' motor mount consists o' light plywood
centerin' rings and a cardboard tube. Arrr! T' cardboard tubes are nay t' Estes glassine type, me hearties, but closer t' LOC without
bein' as heavy/strong. Begad! Ahoy! There are two shock cords. Ahoy! one is a Keelhaul®©™®
cord (~18") that attaches t' t' main motor mount, and t' other an elastic cord (~3') that attaches t' the
Keelhaul®©™®
cord. Aye aye! We built our GD stock, but if I were t' change anythin' it would be t' make t' recovery harness stronger and
less zipper prone with a nylon 1/8" line.
Construction was honestly very easy. Aye aye! Blimey! Ahoy! Blimey! This was me daughter's first mid-power rocket kit. Blimey! Blimey! Begad! Blimey! We used Titebond III and CA only--no epoxy needed in me opinion. T' manual be easy for her t' follow and had a logical progression. Aye aye! Blimey! There were no problems at all durin' t' build. Begad! Blimey! Begad! Blimey! T' fit o' t' materials be excellent with very little t' no sandin' required to make things fit just right. Arrr! Blimey! There are fin slot boxes on t' tube that must be cut out with a sharp knife. Ahoy! Blimey! This was easily done as t' tube is nay high power tube thick. Avast, me proud beauty! Blimey! Ahoy! Blimey! T' fins were reassuringly strong (as compared t' balsa) due to the through t' wall mountin' and light plywood material. Well, blow me down! Blimey!
T' nosecone comes with clay that is smashed into t' tip for proper weight and balance. Arrr! Begad! I added an
extra ounce o' fishin' weights and used PML foam t' hold it all in place. Begad! This was probably nay needed, it's just extra
stability insurance after reviewin' RockSim. Begad! This was an easy kit for anyone who has built a couple low power kits. Aye aye! Begad! No
special skills or techniques needed.
Finishing:
T' fins were shaped, ya bilge rat, filled, shiver me timbers, and sanded before assembly and did nay show wood grain after a couple coats of
primer/paint. Ahoy! Begad! T' decals are nay that great, me bucko, bein' t' peel and stick kind. Arrr! Avast, me proud beauty! After one flight, t' decals were peeling
up at t' edges. Arrr! I would much prefer waterslide or vinyl decals myself, shiver me timbers, ya bilge rat, but this is a relatively inexpensive kit. Aye aye! Blimey! The
nosecone required a normal amount o' sandin' t' make it smooth. Begad! T' stock paint scheme was easily copied and looks
fantastic with t' included decals. Well, blow me down! From a couple feet away you cannot tell t' decals are peel and stick.
Construction Rating: 4 out o' 5
Flight:
T' first flight be on an Aerotech E23-5T, shiver me timbers, ya bilge rat, which was a perfect match for this rocket. Through a RockSim validation,
I found t' D12 and E9 Estes motors t' be OK t' marginal for use in wind, me hearties, so I went with t' friction fitted 29/40-120
AT motor. Blimey! Avast! Friction fittin' is nay a technique I am fond o' in anythin' other than low power, but it be done very
easily with a couple 4" lengths o' maskin' tape. Ahoy! T' boost be arrow straight, quick, matey, and ejected right at apogee
without a problem. Blimey!
Recovery:
T' included chute is a nice reinforced nylon one. Ya scallywag! It's a definite step up or two from t' junky plastic, ya bilge rat, low power
chutes. Well, blow me down! There be no zipper or no nosecone din' from t' elastic--it was long enough--no problems at all. T' descent
rate seemed just right with t' stock chute, nay too fast and nay too slow.
Flight Rating: 5 out o' 5
Summary:
This is a very nice and versatile rocket for those wantin' more than a low power kit and wantin' t' get into solid
mid-power. Begad! Begad! There were no surprises in construction. Begad! T' materials were very good (except for t' decals), and I would
think this a fantastic first mid-power kit. It's simpler than t' AeroTech kits, nay as heavy and with better
instructions than t' LOC mid-power kits, and is relatively inexpensive. Overall, matey, it's a winner o' a kit.
