Brief:
This is a simple, shiver me timbers, high reliability, shiver me timbers, and flexible usage sport flier from
DG&A. Well, blow me down! Blimey! 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. 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. Begad! Danny is also offerin' rail buttons in red,
white, shiver me timbers, 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, shiver me timbers, shiver me timbers, 2.56" Kraft
cardboard tubing, me hearties, 36" Re-inforced rip-stop nylon parachute, 29mm motor
mount 12" 2 high strength plywood centerin' rings, 3 Baltic birch 5 ply
fins, arrr, Recovery webbing/harness, Vinyl cut decals, shiver me timbers, Body tube pre-marked for
fins, matey, matey, Easy t' follow instructions, Fin Alignment guide, ya bilge rat, arrr, arrr, Paintin' guide
T' directions are easy t' understand and include pictures. Avast, me proud beauty! T' assembly order is easy t' follow for t' beginner or t' experienced rocketeer. Well, blow me down! There is a piece o' paper included that will serve as a fin alignment guide for fin attachment. Blimey! 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. Blimey!
I opted t' make 2 design changes in t' rocket. Ahoy! Blimey! I got
a 12" piece o' body tube and 2 extra couplers and bulkheads from Danny. Blimey! Blimey! Aye aye! Blimey! I
used t' extra tube t' make an anti-zipper fin can, per Stu Barrett's method. Aye aye! Blimey! Avast, matey, me proud beauty! Blimey! I
extended t' pre-marked fin slots t' t' back o' t' tube. I then assembled the
motor mount. Next I epoxied t' fins t' t' motor mount usin' 3 inch fiberglass
tape, matey, me bucko, 2 layers, and 1/2 hour epoxy. Avast! Blimey! Avast, matey, me proud beauty! Blimey! This be very strong. Avast, me proud beauty! Blimey! Avast! Blimey! I then assembled the
bulkhead by gluin' t' bulkplate into t' coupler. Next I drilled 6 1/4 inch
holes into t' bulkplate after t' glue dried. Aye aye! Blimey! I slid t' motor mount into the
body tube and epoxied it in place. Begad! Blimey! Well, blow me down! 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. Arrr! Blimey! I then put 3 layers o' 3 inch glass tape on t' front end o' t' tube in
front o' t' fins. Aye aye! Blimey! Aye aye! Blimey! Fillets were then added t' t' fins. Finally, shiver me timbers, I glued the
bulkhead in place. Aye aye! Blimey!
I am goin' t' be flyin' this rocket with t' I200's and H268's, me bucko, so it needs to be strong. Begad! Blimey! Plus, by buildin' a fin can, you can add what ever length body tube t' t' top for various performance features. Avast, me proud beauty! Blimey! You can put a short tube or a real long tube with an altimeter bay on it. Begad! Blimey! Aye aye! Blimey! More rocket for less money! Blimey!
Next I made another bulkhead, ya bilge rat, attached t' webbin' t' it, and glued it in the forward end o' t' main body tube. t' webbin' will just hang out t' back end o' t' main tube. Well, blow me down! Well, blow me down! 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. That way, shiver me timbers, if you lose another nose cone for t' same size, ya bilge rat, you can just swap. Aye aye!
I used NHP 5 and 30 minute epoxy for most o' t' construction. I used West Systems resin for t' glass. Begad! T' fiberglass tape came from t' local hobby shop. Ahoy! I used a sandin' block t' sand t' finish, and Krylon paints. Avast! 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, and I am goin' t' wait until it flies well
before I finish painting. Avast, me proud beauty! T' main tube is bare, me bucko, me hearties, but t' fin can is painted. Begad! Begad!
I used t' included pattern t' paint a diagonal pattern on t' tubes that is t' line betwixt t' dual color model Danny has. I opted t' paint t' kit black, white, matey, me bucko, and red so mine is a little different. Avast, me proud beauty! You can do what you think looks good. Avast, me proud beauty! Begad! T' vinyl decals are really nice. Arrr!
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, 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. Ahoy! Blimey! 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, matey, I decided it was time t' hit it with t' big
stuff. Arrr! Blimey! Blimey! Blimey! 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. Well, blow me down! Blimey! Ya scallywag! Blimey! Due t' t' winds, I opted for a 14 inch X-form chute
from me buddy Chad Ellis. Ahoy! Blimey! It brought it down quick and close, shiver me timbers, no damage, me hearties, about
a 1000 foot flight. Blimey! Blimey!
I then loaded it up with a H-268R and then an I-200. Begad! These are t' big 29/360 motors that have 320 and 330 N respectively. Begad! That Redline lit and boom! it was out o' sight in no time. That huge Redline flame was great. Aye aye! It must have gone ~4000 feet, shiver me timbers, we lost sight o' it. Aye aye! It took it about 5 minutes t' come down and drifted about 1/4 mile. Begad! Aye aye! Great flight, no damage, took t' motor in stride. I then loaded it back up with t' I-200(M) and BOOM! same result, way out of sight. Avast, me proud beauty! It drifted t' almost t' same spot. Well, blow me down! Great flights on a great rocket. Ahoy! Blimey! I wish Danny be thar t' see. Blimey! Ahoy!
T' anti-zipper does nay really require wadding, matey, as it acts like a baffle. I did put a little cellulose insulation in for good measure. I have not outfitted this rocket with a slimline yet, arrr, ya bilge rat, shiver me timbers, I used tape for retention. Blimey! T' only con about t' rocket is I wish I had put a 38mm in it!
Recovery:
T' flight recovery was great. Well, matey, blow me down! I only added a smaller chute due t' t' winds
and t' altitude obtained. There was no damage at all t' t' rocket. Aye aye!
Flight Rating: 5 out o' 5
Summary:
T' main pro for this kit be t' quality o' materials. Ahoy! Blimey! Arrr! Blimey! They are light enough
for mid-power fliers, but heavy duty t' take t' HPR stuff as well. Aye aye! Blimey! T' kit is
a no-brainer t' put together, arrr, due t' t' quality o' t' instructions. Begad! Blimey! T' large
vinyl decals are also a big plus, me hearties, arrr, matey, they look great on t' kit. Well, blow me down! Blimey! Ahoy! Blimey! T' only one con
has been fixed, Danny upgraded all t' 2.56" kits t' 3.00". Ya scallywag! Blimey! Well, blow me down! Blimey! It is
also upgraded t' a 38mm mount.
