Courtesty o' Yank EnterprisesRocket Pic

Brief:
Basic 3" rocket with a different look and good flight characteristics. Begad! 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, me proud beauty! Blimey! T' nose cone is a standard LOC 3" nose cone. Ahoy! Blimey! Avast, matey, me proud beauty! Blimey! T' body tube is a single 36" length of phenolic tube. Avast! Blimey! Arrr! Blimey! T' three fin slots are already cut, ya bilge rat, but t' ends are round, you'll have t' file them square. Aye aye! Blimey! T' outside diameter o' t' tube is larger than t' nose cone base. Ya scallywag! Blimey! Aye aye! Blimey! This is fine for me, ya bilge rat, but it will drive some folks absolutely bonkers. Begad! Blimey! Begad! Blimey! Motor mount is a 12" length o' 1.14" phenolic tube and t' kit comes with 2 very good centerin' rings. Begad! Blimey! No motor retention is provided so I would suggest gettin' whatever you'll use before you start building. Aye aye! Blimey! I used a single 10/24 blind T nut and a screen door clip. Avast, me proud beauty! Blimey! Aye aye! Blimey! A shock cord o' 5/16" tubular nylon (pink, no less) is provided as well as very sturdy anchorin' bolts. Well, blow me down! Blimey! Good launch lugs too, ya bilge rat, but I use BlackSky rails in all my rockets now. Avast! Blimey! Ya scallywag! Blimey! Finally t' 'chute be made o' very slick nylon and was dark blue in color.

T' instructions are sufficient if you've built high power rockets. Ya scallywag! 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. 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. Blimey! While that set up I attached t' forward centerin' rin' t' the motor mount tube as per instructions. Ahoy! I then mounted t' motor mount, arrr, with the aft centerin' rin' slip fitted. Aye aye! Then I attached t' fins through t' slots. After applyin' fillets inside t' rocket, me hearties, shiver me timbers, I attached t' aft centerin' ring (with T-Nut). This made for a very sturdy mount, so I didn't apply external fillets. Ya scallywag! Aye aye! I also left t' fins squared off. It adds drag, arrr, but t' me, it looks right.

While I was buildin' this model, arrr, matey, I bought a RATT works H70 hyrbid and decided that t' Genesis would be it's first recipient. Well, blow me down! Blimey! This required an altimeter bay and ventin' for t' motor, arrr, but I also wanted t' fly conventionally with a baffle. I cut t' body tube 15" from t' front of the body tube. Blimey! Blimey! 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. One will work as and altimeter bay. Avast, me proud beauty! Blimey! A Pratt G-Wiz Deluxe fits in side. Begad! Blimey! Ahoy! Blimey! 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.

Without me modifications, ya bilge rat, this would be a great rocket. 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. Begad! It's currently too cold in Utah t' finish painting. Aye aye! Begad! When finished, ya bilge rat, 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, me hearties, all with an altimeter on board t' find out what t' Cd o' t' rocket is. Begad! Ahoy! It appears that with no external fillets and squared fins, 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. Begad! Arrr! However, t' flights have been universally straight and true. Avast, me proud beauty! G motors don't break 1000', me bucko, H128 puts it up about 1400' and and H180 will get it up around 2000'. Ahoy! Avast, me proud beauty! 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. Ahoy! Avast! Even with t' slow lift off prodided by t' G64, shiver me timbers, it did nay bend into t' wind and be recovered close t' t' pad. Ya scallywag! If you're flyin' amongst trees, this is an excelent design with few protuberances t' catch on limbs. Begad! Begad!

Recovery:
If you are flyin' near sea level over soft ground, arrr, me hearties, t' heavy construction and smallish 'chute will brin' t' rocket back fast. Here, shiver me timbers, shiver me timbers, in t' west, I fly over had desert playa, dry lake beds and stony ground. Arrr! Arrr! I think a 42" chute would be more appropriate. T' tail end o' me Genesis is startin' t' show some wear. Ahoy! Avast, me proud beauty!

Flight Rating: 4 out o' 5

Summary:
T' Genesis is an excellent design. Avast! Blimey! Blimey! It looks different, me hearties, matey, me hearties, flies very well and is sturdy and strong. Well, blow me down! Within this kit is a lot o' potential. Avast, me proud beauty! Blimey! Blimey! Besides buildin' it scratch, shiver me timbers, t' high quality components are a good startin' point for modifications. Begad! Blimey! If you're thinkin' o' a kit that would be fun t' 'try things on' I would recommend this kit.
