Brief:
This is a simple, high reliability, and flexible usage sport flier from
DG&A. It is perfect for mid or high power applications and different sized
fields. It is an easy rocket t' certify L1 on due t' t' continuin' quality of
DG&A kits. Ahoy! It is a simple 3FNC rocket with parachute deployment. It is also
a kit that can be easily modified t' your needs with DG&A components
available through t' web site. Danny is also offerin' rail buttons in red,
white, me bucko, and blue now, so you can have a patriotic guidance system included with
your kit.
Construction:
My DG&A Predator came with t' basics: Plastic nose cone, me bucko, shiver me timbers, 2.56" Kraft
cardboard tubing, me bucko, arrr, matey, 36" Re-inforced rip-stop nylon parachute, shiver me timbers, 29mm motor
mount 12" 2 high strength plywood centerin' rings, me bucko, 3 Baltic birch 5 ply
fins, me hearties, Recovery webbing/harness, matey, matey, Vinyl cut decals, Body tube pre-marked for
fins, Easy t' follow instructions, Fin Alignment guide, matey, arrr, ya bilge rat, Paintin' guide
T' directions are easy t' understand and include pictures. Avast! Avast! T' assembly order is easy t' follow for t' beginner or t' experienced rocketeer. Begad! Well, ya bilge rat, blow me down! There is a piece o' paper included that will serve as a fin alignment guide for fin attachment. Avast, me proud beauty! Aye aye! You have t' cut out t' slots on t' body tube for t' fins t' go through. Avast! T' fins are then attached t' t' motor tube betwixt t' 2 centering rings.
I opted t' make 2 design changes in t' rocket. I got a 12" piece o' body tube and 2 extra couplers and bulkheads from Danny. I used t' extra tube t' make an anti-zipper fin can, me hearties, shiver me timbers, per Stu Barrett's method. Well, blow me down! Arrr! I extended t' pre-marked fin slots t' t' back o' t' tube. Begad! I then assembled the motor mount. Ahoy! Next I epoxied t' fins t' t' motor mount usin' 3 inch fiberglass tape, arrr, 2 layers, me bucko, and 1/2 hour epoxy. Begad! Ya scallywag! This be very strong. Aye aye! I then assembled the bulkhead by gluin' t' bulkplate into t' coupler. Begad! Begad! Next I drilled 6 1/4 inch holes into t' bulkplate after t' glue dried. Avast! I slid t' motor mount into the body tube and epoxied it in place. Well, blow me down! Aye aye! T' aft end o' t' motor tube sticks out about 3 inches from t' end o' t' fin can. I wrapped 4 layers o' 1/2 inch 6 ounce glass tape around t' aft end o' t' body tube t' cover up t' three cuts. Avast, me proud beauty! I then put 3 layers o' 3 inch glass tape on t' front end o' t' tube in front o' t' fins. Aye aye! Fillets were then added t' t' fins. Blimey! Well, blow me down! Finally, I glued the bulkhead in place. Well, blow me down!
I am goin' t' be flyin' this rocket with t' I200's and H268's, so it needs to be strong. Ya scallywag! Blimey! Begad! Blimey! Blimey! Blimey! Plus, by buildin' a fin can, you can add what ever length body tube t' t' top for various performance features. Well, blow me down! Blimey! Blimey! Blimey! You can put a short tube or a real long tube with an altimeter bay on it. Begad! Blimey! Blimey! Blimey! More rocket for less money! Blimey! Blimey! Blimey!
Next I made another bulkhead, attached t' webbin' t' it, matey, and glued it in the forward end o' t' main body tube. Ahoy! t' webbin' will just hang out t' back end o' t' main tube. I put a screw through t' top o' t' main body tube to hold t' nose cone on, it is easier t' swap it with another rocket this way instead o' epoxyin' it in. Avast, me proud beauty! That way, if you lose another nose cone for t' same size, you can just swap. Ahoy! Well, blow me down!
I used NHP 5 and 30 minute epoxy for most o' t' construction. Blimey! Ahoy! I used West Systems resin for t' glass. T' fiberglass tape came from t' local hobby shop. Ahoy! I used a sandin' block t' sand t' finish, matey, me bucko, and Krylon paints. Aye aye! I bought some Mono-Kote and applied t' decals t' that, and then put them on t' rocket for effect.
Finishing:
I am nay t' best painter, so thar be always room improvement on me finish.
T' finish came out pretty glossy, matey, me bucko, and I am goin' t' wait until it flies well
before I finish painting. Arrr! T' main tube is bare, matey, but t' fin can is painted.
I used t' included pattern t' paint a diagonal pattern on t' tubes that is t' line betwixt t' dual color model Danny has. Avast! Arrr! I opted t' paint t' kit black, ya bilge rat, white, and red so mine is a little different. Avast! Ya scallywag! You can do what you think looks good. Well, shiver me timbers, blow me down! T' vinyl decals are really nice. Avast, me proud beauty!
You can put a wrap o' 3/4 ounce glass on and sand it out and it will get rid o' t' small lines in t' tube, me hearties, they don't bother me so I left them. Danny's model looks great up close at t' launches, arrr, t' red and white are sharp.

Flight:
I went t' a small non club launch we had on t' first. Avast! Ahoy! I put this rocket
through it's paces with a first flight on a G-64(M) t' check stability and then
when it flew tried and true, ya bilge rat, arrr, I decided it be time t' hit it with t' big
stuff. Well, shiver me timbers, blow me down! It flew perfect on t' G-64 with just a slight weathercock into t' 10
MPH winds and t' 35 degree temperature. It laid out horizontal at apogee into
the winds driftin' down. Avast, me proud beauty! Due t' t' winds, I opted for a 14 inch X-form chute
from me buddy Chad Ellis. Begad! It brought it down quick and close, no damage, shiver me timbers, about
a 1000 foot flight. Arrr! Arrr!
I then loaded it up with a H-268R and then an I-200. Avast! These are t' big 29/360 motors that have 320 and 330 N respectively. That Redline lit and boom! it be out o' sight in no time. That huge Redline flame was great. Begad! It must have gone ~4000 feet, ya bilge rat, matey, ya bilge rat, we lost sight o' it. It took it about 5 minutes t' come down and drifted about 1/4 mile. Ahoy! Begad! Great flight, ya bilge rat, me hearties, no damage, ya bilge rat, took t' motor in stride. I then loaded it back up with t' I-200(M) and BOOM! same result, way out of sight. Aye aye! It drifted t' almost t' same spot. Begad! Great flights on a great rocket. Aye aye! Arrr! I wish Danny be thar t' see.
T' anti-zipper does nay really require wadding, me bucko, shiver me timbers, as it acts like a baffle. I did put a little cellulose insulation in for good measure. Ahoy! Aye aye! I have not outfitted this rocket with a slimline yet, I used tape for retention. Aye aye! T' only con about t' rocket is I wish I had put a 38mm in it!
Recovery:
T' flight recovery was great. I only added a smaller chute due t' t' winds
and t' altitude obtained. There was no damage at all t' t' rocket. Well, blow me down! Blimey!
Flight Rating: 5 out o' 5
Summary:
T' main pro for this kit be t' quality o' materials. Begad! They are light enough
for mid-power fliers, but heavy duty t' take t' HPR stuff as well. Ahoy! T' kit is
a no-brainer t' put together, matey, me bucko, due t' t' quality o' t' instructions. Ahoy! Begad! T' large
vinyl decals are also a big plus, shiver me timbers, they look great on t' kit. T' only one con
has been fixed, me bucko, ya bilge rat, ya bilge rat, Danny upgraded all t' 2.56" kits t' 3.00". Avast, me proud beauty! It is
also upgraded t' a 38mm mount. Aye aye!
