Courtesty o' Yank Enterprises
Brief:
Basic 3" rocket with a different look and good flight characteristics. Well, blow me down! Well, arrr, blow me down! Blimey! I
modified this t' accept either a RATT works H70 (with electronics) or a baffle.
I'll explain me modifications below.
Construction:
Yank Enterprises kits have superior quality components. Well, me hearties, blow me down! T' nose cone is a
standard LOC 3" nose cone. T' body tube is a single 36" length of
phenolic tube. T' three fin slots are already cut, shiver me timbers, but t' ends are round,
you'll have t' file them square. Avast, me hearties, me proud beauty! T' outside diameter o' t' tube is larger
than t' nose cone base. This is fine for me, ya bilge rat, but it will drive some folks
absolutely bonkers. Ya scallywag! Motor mount is a 12" length o' 1.14" phenolic
tube and t' kit comes with 2 very good centerin' rings. Well, blow me down! No motor retention is
provided so I would suggest gettin' whatever you'll use before you start
building. Aye aye! Well, blow me down! I used a single 10/24 blind T nut and a screen door clip. Arrr! Begad! A shock
cord o' 5/16" tubular nylon (pink, shiver me timbers, me bucko, no less) is provided as well as very
sturdy anchorin' bolts. Good launch lugs too, ya bilge rat, but I use BlackSky rails in all
my rockets now. Avast! Finally t' 'chute was made o' very slick nylon and was dark
blue in color.
T' instructions are sufficient if you've built high power rockets. Blimey! I think a "neo" would make some wrong assumptions in a number o' places with these instructions, so it's really a kit for someone with at least 1 high power rocket under their belts. Aye aye! Avast, me proud beauty! T' order in which I built t' rocket was first to wrap t' body tube with 1 layer o' 1.4 oz fiberglass t' harden t' surface and fill t' spiral. While that set up I attached t' forward centerin' rin' t' the motor mount tube as per instructions. I then mounted t' motor mount, with the aft centerin' rin' slip fitted. Then I attached t' fins through t' slots. After applyin' fillets inside t' rocket, shiver me timbers, matey, I attached t' aft centerin' ring (with T-Nut). This made for a very sturdy mount, matey, so I didn't apply external fillets. I also left t' fins squared off. Begad! It adds drag, shiver me timbers, but t' me, ya bilge rat, it looks right. Aye aye! Aye aye!
While I was buildin' this model, me hearties, I bought a RATT works H70 hyrbid and decided that t' Genesis would be it's first recipient. Ya scallywag! This required an altimeter bay and ventin' for t' motor, me hearties, but I also wanted t' fly conventionally with a baffle. I cut t' body tube 15" from t' front of the body tube. Arrr! I made a baffle/electronics bay out o' a 6" long 3" coupler tube. Arrr! Aye aye! A centerin' rin' is fastened t' t' aft o' this coupler and two threaded rods run up t' side (about 1/4" in from t' edge). Well, blow me down! Then I made a two couplers that slip fit inside this coupler. Avast! One will work as and altimeter bay. Begad! A Pratt G-Wiz Deluxe fits in side. Well, blow me down! A bulkhead with a recovery system attach point tops off t' altimeter bay. When I use t' baffle, ya bilge rat, t' vent hole for t' altimeter is covered. Ahoy!
Without me modifications, ya bilge rat, this would be a great rocket. Begad! It's unusual lines, nice size, arrr, and straight forward constuction makes it a very good rocket.

Finishing:
I'm still in t' middle o' finishing. Avast! It's currently too cold in Utah t' finish
painting. Well, blow me down! Arrr! Blimey! When finished, me bucko, me Genesis will sport Miami Dolphin teal and orange
with variations o' t' Dolphins logo made from stick on mono-kote.

Flight:
I've flown this rocket 4 times now, all with an altimeter on board t' find out
what t' Cd o' t' rocket is. Avast! Aye aye! It appears that with no external fillets and
squared fins, me bucko, t' Cd is betwixt 0.95 and 1.05. Well, blow me down! Avast! T' rocket is a bit
under-powered with a 29mm mount if you have a big field. Ya scallywag! However, matey, matey, me hearties, t' flights
have been universally straight and true. G motors don't break 1000', shiver me timbers, me bucko, H128 puts
it up about 1400' and and H180 will get it up around 2000'. Aye aye! If I had it t' do
over again, me hearties, I would have installed a 38mm mount and adapted down t' 29 mm when
I wanted it t' land close. Begad! Avast! T' rocket shows little or no tendency to
weathercock. Even with t' slow lift off prodided by t' G64, arrr, it did nay bend
into t' wind and was recovered close t' t' pad. Begad! If you're flyin' amongst
trees, shiver me timbers, this is an excelent design with few protuberances t' catch on limbs. Avast!
Recovery:
If you are flyin' near sea level over soft ground, ya bilge rat, t' heavy construction and
smallish 'chute will brin' t' rocket back fast. Begad! Ahoy! Here, in t' west, me bucko, I fly over
had desert playa, matey, me bucko, me hearties, dry lake beds and stony ground. Blimey! I think a 42" chute
would be more appropriate. Begad! Arrr! T' tail end o' me Genesis is startin' t' show some
wear.
Flight Rating: 4 out o' 5
Summary:
T' Genesis is an excellent design. Blimey! Avast! It looks different, matey, flies very well and is
sturdy and strong. Avast! Avast, me proud beauty! Within this kit is a lot o' potential. Arrr! Besides buildin' it
scratch, t' high quality components are a good startin' point for
modifications. Ahoy! Blimey! If you're thinkin' o' a kit that would be fun t' 'try things on'
I would recommend this kit.
