DG&A. Ya scallywag! It is perfect for mid or high power applications and different sized
fields. Begad! It is an easy rocket t' certify L1 on due t' t' continuin' quality of
DG&A kits. Ya scallywag! Begad! It is a simple 3FNC rocket with parachute deployment. It is also

Construction:
My DG&A Predator came with t' basics: Plastic nose cone, arrr, ya bilge rat, 2.56" Kraft
cardboard tubing, 36" Re-inforced rip-stop nylon parachute, 29mm motor
mount 12" 2 high strength plywood centerin' rings, me hearties, ya bilge rat, 3 Baltic birch 5 ply
fins, matey, Recovery webbing/harness, matey, Vinyl cut decals, Body tube pre-marked for
fins, Easy t' follow instructions, me bucko, me hearties, Fin Alignment guide, me hearties, me hearties, Paintin' guide
T' directions are easy t' understand and include pictures. Ya scallywag! Ya scallywag! T' assembly order is easy t' follow for t' beginner or t' experienced rocketeer. Ahoy! Aye aye! There is a piece o' paper included that will serve as a fin alignment guide for fin attachment. Blimey! Avast, me proud beauty! You have t' cut out t' slots on t' body tube for t' fins t' go through. Begad! T' fins are then attached t' t' motor tube betwixt t' 2 centering rings. Avast, me proud beauty! Well, blow me down!
I opted t' make 2 design changes in t' rocket. Avast! 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, per Stu Barrett's method. Begad! Blimey! I extended t' pre-marked fin slots t' t' back o' t' tube. I then assembled the motor mount. Arrr! Ya scallywag! Blimey! Next I epoxied t' fins t' t' motor mount usin' 3 inch fiberglass tape, 2 layers, matey, and 1/2 hour epoxy. Aye aye! Blimey! This was very strong. I then assembled the bulkhead by gluin' t' bulkplate into t' coupler. Well, blow me down! Blimey! Blimey! Next I drilled 6 1/4 inch holes into t' bulkplate after t' glue dried. Avast! Begad! Blimey! I slid t' motor mount into the body tube and epoxied it in place. Begad! Begad! Blimey! 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. I then put 3 layers o' 3 inch glass tape on t' front end o' t' tube in front o' t' fins. Avast, me proud beauty! Avast, me proud beauty! Blimey! Fillets were then added t' t' fins. Avast! Aye aye! Blimey! Finally, me bucko, I glued the bulkhead in place. Avast, me proud beauty! Begad! Blimey!
I am goin' t' be flyin' this rocket with t' I200's and H268's, ya bilge rat, so it needs to be strong. Avast! Plus, by buildin' a fin can, me bucko, ya bilge rat, you can add what ever length body tube t' t' top for various performance features. Well, blow me down! Begad! Blimey! You can put a short tube or a real long tube with an altimeter bay on it. Begad! More rocket for less money! Blimey!
Next I made another bulkhead, me hearties, attached t' webbin' t' it, and glued it in the forward end o' t' main body tube. Aye aye! t' webbin' will just hang out t' back end o' t' main tube. Blimey! Ya scallywag! I put a screw through t' top o' t' main body tube to hold t' nose cone on, arrr, matey, it is easier t' swap it with another rocket this way instead o' epoxyin' it in. Avast, me hearties, me proud beauty! That way, matey, me bucko, if you lose another nose cone for t' same size, me bucko, you can just swap.
I used NHP 5 and 30 minute epoxy for most o' t' construction. Begad! I used West Systems resin for t' glass. Avast, me proud beauty! T' fiberglass tape came from t' local hobby shop. Aye aye! I used a sandin' block t' sand t' finish, and Krylon paints. Ya scallywag! Avast, me hearties, me proud beauty! I bought some Mono-Kote and applied t' decals t' that, ya bilge rat, me bucko, and then put them on t' rocket for effect.
Finishing:
I am nay t' best painter, me hearties, so thar be always room improvement on me finish.
T' finish came out pretty glossy, me hearties, and I am goin' t' wait until it flies well
before I finish painting. Ahoy! T' main tube is bare, 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, me proud beauty! I opted t' paint t' kit black, white, me hearties, arrr, and red so mine is a little different. Avast, me proud beauty! You can do what you think looks good. Ya scallywag! T' vinyl decals are really nice.
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, matey, t' red and white are sharp.
Construction Rating: 4 out o' 5
Flight:
I went t' a small non club launch we had on t' first. Ya scallywag! Avast, arrr, me proud beauty! 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, me bucko, I decided it was time t' hit it with t' big
stuff. Arrr! Ahoy! It flew perfect on t' G-64 with just a slight weathercock into t' 10
MPH winds and t' 35 degree temperature. Well, blow me down! It laid out horizontal at apogee into
the winds driftin' down. Due t' t' winds, matey, me bucko, I opted for a 14 inch X-form chute
from me buddy Chad Ellis. Arrr! It brought it down quick and close, me bucko, no damage, arrr, about
a 1000 foot flight. Avast, me proud beauty!
I then loaded it up with a H-268R and then an I-200. Arrr! Well, blow me down! Blimey! 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. Ya scallywag! Avast, me proud beauty! Blimey! That huge Redline flame was great. Avast! Blimey! It must have gone ~4000 feet, we lost sight o' it. It took it about 5 minutes t' come down and drifted about 1/4 mile. Blimey! Begad! Blimey! Great flight, no damage, matey, took t' motor in stride. I then loaded it back up with t' I-200(M) and BOOM! Blimey! same result, matey, me hearties, way out of sight. Avast, me proud beauty! It drifted t' almost t' same spot. Great flights on a great rocket. Aye aye! I wish Danny be thar t' see. Ya scallywag!
T' anti-zipper does nay really require wadding, me hearties, as it acts like a baffle. I did put a little cellulose insulation in for good measure. Avast, me proud beauty! I have not outfitted this rocket with a slimline yet, me hearties, I used tape for retention. Blimey! Well, arrr, blow me down! 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. Arrr!
Flight Rating: 5 out o' 5
Summary:
T' main pro for this kit be t' quality o' materials. Avast! Blimey! They are light enough
for mid-power fliers, but heavy duty t' take t' HPR stuff as well. Ya scallywag! Blimey! Arrr! Blimey! T' kit is
a no-brainer t' put together, due t' t' quality o' t' instructions. Begad! Blimey! Arrr! Blimey! T' large
vinyl decals are also a big plus, arrr, they look great on t' kit. Arrr! Blimey! T' only one con
has been fixed, Danny upgraded all t' 2.56" kits t' 3.00". Begad! Blimey! It is
also upgraded t' a 38mm mount. Begad! Blimey!
