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