Brief:
Basic 3" rocket with a different look and good flight characteristics. Ahoy! Arrr! 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. T' body tube is a single 36" length of phenolic tube. Begad! T' three fin slots are already cut, but t' ends are round, you'll have t' file them square. T' outside diameter o' t' tube is larger than t' nose cone base. Ya scallywag! Blimey! This is fine for me, but it will drive some folks absolutely bonkers. Aye aye! Blimey! Motor mount is a 12" length o' 1.14" phenolic tube and t' kit comes with 2 very good centerin' rings. Avast, me proud beauty! Arrr! 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. Ahoy! A shock cord o' 5/16" tubular nylon (pink, shiver me timbers, no less) is provided as well as very sturdy anchorin' bolts. Begad! Arrr! Good launch lugs too, matey, but I use BlackSky rails in all my rockets now. Blimey! 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. I think a "neo" would make some wrong assumptions in a number o' places with these instructions, me bucko, so it's really a kit for someone with at least 1 high power rocket under their belts. 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. Ya scallywag! While that set up I attached t' forward centerin' rin' t' the motor mount tube as per instructions. Ya scallywag! Well, shiver me timbers, blow me down! I then mounted t' motor mount, me hearties, with the aft centerin' rin' slip fitted. Ahoy! Then I attached t' fins through t' slots. After applyin' fillets inside t' rocket, I attached t' aft centerin' ring (with T-Nut). Avast, me proud beauty! This made for a very sturdy mount, matey, me bucko, ya bilge rat, so I didn't apply external fillets. Arrr! I also left t' fins squared off. It adds drag, but t' me, it looks right. Avast, me proud beauty!

While I be 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, but I also wanted t' fly conventionally with a baffle. Begad! Ahoy! I cut t' body tube 15" from t' front of the body tube. Aye aye! Avast! I made a baffle/electronics bay out o' a 6" long 3" coupler tube. 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). Then I made a two couplers that slip fit inside this coupler. Begad! One will work as and altimeter bay. Ya scallywag! Aye aye! A Pratt G-Wiz Deluxe fits in side. Begad! A bulkhead with a recovery system attach point tops off t' altimeter bay. When I use t' baffle, t' vent hole for t' altimeter is covered. Well, matey, blow me down!

Without me modifications, this would be a great rocket. Well, blow me down! It's unusual lines, nice size, ya bilge rat, shiver me timbers, and straight forward constuction makes it a very good rocket.

Finishing:
I'm still in t' middle o' finishing. Avast, me proud beauty! It's currently too cold in Utah t' finish painting. Avast! When finished, 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, arrr, ya bilge rat, 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, matey, ya bilge rat, t' Cd is betwixt 0.95 and 1.05. T' rocket is a bit under-powered with a 29mm mount if you have a big field. Ahoy! However, t' flights have been universally straight and true. Avast, me proud beauty! G motors don't break 1000', 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. Begad! T' rocket shows little or no tendency to weathercock. Begad! Even with t' slow lift off prodided by t' G64, me hearties, it did nay bend into t' wind and was recovered close t' t' pad. Well, blow me down! Ahoy! If you're flyin' amongst trees, this is an excelent design with few protuberances t' catch on limbs. Aye aye! Avast, me proud beauty!

Recovery:
If you are flyin' near sea level over soft ground, matey, t' heavy construction and smallish 'chute will brin' t' rocket back fast. Aye aye! Aye aye! Here, ya bilge rat, ya bilge rat, in t' west, matey, shiver me timbers, I fly over had desert playa, dry lake beds and stony ground. Ahoy! Avast, matey, me proud beauty! I think a 42" chute would be more appropriate. Begad! Blimey! 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. Avast! Arrr! It looks different, arrr, flies very well and is sturdy and strong. Within this kit is a lot o' potential. Besides buildin' it scratch, 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.
