Courtesty o' Yank EnterprisesRocket Pic

Brief:
Basic 3" rocket with a different look and good flight characteristics. Avast! 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. Ya scallywag! T' nose cone is a standard LOC 3" nose cone. Blimey! T' body tube is a single 36" length of phenolic tube. Begad! T' three fin slots are already cut, me bucko, 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. Well, blow me down! This is fine for me, ya bilge rat, 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. Aye aye! No motor retention is provided so I would suggest gettin' whatever you'll use before you start building. Ya scallywag! Ahoy! I used a single 10/24 blind T nut and a screen door clip. Ahoy! A shock cord o' 5/16" tubular nylon (pink, no less) is provided as well as very sturdy anchorin' bolts. Begad! Good launch lugs too, but I use BlackSky rails in all my rockets now. Ya scallywag! Finally t' 'chute be made o' very slick nylon and be dark blue in color.

T' instructions are sufficient if you've built high power rockets. Avast! Begad! I think a "neo" would make some wrong assumptions in a number o' places with these instructions, shiver me timbers, so it's really a kit for someone with at least 1 high power rocket under their belts. Avast! 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. Ahoy! Begad! I then mounted t' motor mount, with the aft centerin' rin' slip fitted. Begad! Then I attached t' fins through t' slots. After applyin' fillets inside t' rocket, I attached t' aft centerin' ring (with T-Nut). Avast! Avast! This made for a very sturdy mount, so I didn't apply external fillets. I also left t' fins squared off. Blimey! Well, blow me down! It adds drag, but t' me, arrr, matey, shiver me timbers, it looks right. Ahoy!

While I was buildin' this model, ya bilge rat, I bought a RATT works H70 hyrbid and decided that t' Genesis would be it's first recipient. Well, blow me down! Blimey! Well, me bucko, blow me down! Blimey! This required an altimeter bay and ventin' for t' motor, but I also wanted t' fly conventionally with a baffle. Begad! Blimey! Ya scallywag! Blimey! I cut t' body tube 15" from t' front of the body tube. Arrr! 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). Begad! Blimey! Aye aye! Blimey! Then I made a two couplers that slip fit inside this coupler. Well, blow me down! Blimey! One will work as and altimeter bay. Avast! Blimey! A Pratt G-Wiz Deluxe fits in side. Ya scallywag! Blimey! A bulkhead with a recovery system attach point tops off t' altimeter bay. When I use t' baffle, matey, t' vent hole for t' altimeter is covered. Aye aye! Blimey!

Without me modifications, this would be a great rocket. Ya scallywag! Aye aye! 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. Well, blow me down! It's currently too cold in Utah t' finish painting. When finished, shiver me timbers, me bucko, 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, arrr, 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, 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! Blimey! However, me hearties, t' flights have been universally straight and true. Arrr! Blimey! Ahoy! Blimey! G motors don't break 1000', ya bilge rat, H128 puts it up about 1400' and and H180 will get it up around 2000'. Avast! Blimey! 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. Ahoy! Blimey! T' rocket shows little or no tendency to weathercock. Arrr! Blimey! Even with t' slow lift off prodided by t' G64, it did nay bend into t' wind and was recovered close t' t' pad. Aye aye! Blimey! Ahoy! Blimey! If you're flyin' amongst trees, this is an excelent design with few protuberances t' catch on limbs. Arrr! Blimey! Ya scallywag! Blimey!

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

Flight Rating: 4 out o' 5

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