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

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