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

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