Brief:
T' DG&A Archblast is a single staged 29mm rocket that boasts beefy wood
parts, me bucko, includes decals, as well as a photo illustrated instruction guide. Ahoy! The
rocket stands at 47" when complete. It could probably serve well as a L1
rocket.
[Editor's Note: DG&A has converted this kit t' a 3" diameter and it now stands 59" tall and uses a 38mm Motor Mount]
Construction:
I received t' Archblast from EMRR after winnin' one o' their Rocket Give-Away drawings. Arrr! Blimey! T' kit I received
came in a box with t' components secured and undamaged. Arrr! Blimey! Avast! Blimey! Here's t' breakdown
of t' parts list per t' instruction booklet:
NOTE: T' inventory list o' t' kit's
instructions also mentioned a quick link which was nay present. Also mentioned
in t' kit's inventory list but nay found were retention screws for t' motor
anchorin' duties (I assume this was a fluke). No biggie, me hearties, though, since
retention screws and quick links are inexpensive at t' local hardware store. Ahoy!
T' construction o' t' Archblast shouldn't be too tough if one is familiar with t' basic components o' a mid or high-powered rockets. Arrr! Blimey! No doubt, the pictures for each step o' t' build can help clarify things. Avast, me proud beauty! Blimey! I used Bob Smith 15 minute epoxy for t' entire build and am confident that everythin' will hold together. I also must add that this be t' first rocket in some time that I built essentially stock.
T' wood components required some sanding, ya bilge rat, particularly t' fins, matey, ya bilge rat, t' smooth out t' surface, arrr, but nothin' major. Avast! I rounded t' leadin' edges o' t' each fin for aesthetics before gettin' started on t' buildin' process. Avast! I found the centerin' rings were a bit rough around t' edges, me hearties, but nonetheless, they "dry-fit" together on t' motor tube well. As one might guess, ya bilge rat, the motor mount components were t' first things t' be adhered together. I supplied my own t-nuts and added them on t' aft centerin' rin' 180 degrees apart. Ahoy! Aye aye! The instructions direct t' builder t' epoxy both centerin' rings on t' motor tube prior t' installin' it in t' airframe. Ahoy! I deviated slightly from the instructions here because I opted t' epoxy t' forward rin' on first and dry fit t' rearward rin' on because I wanted t' add internal fillets t' t' fins. Hence, I applied epoxy at t' correct depth inside t' airframe for t' forward centerin' rin' and pushed t' assembly in t' t' desired depth. I removed the rear centerin' rin' after things had dried and started mountin' t' fins. Aye aye! After givin' t' fins internal fillets, ya bilge rat, I epoxied t' aft centerin' rin' on. Arrr!
T' Archblast employs through t' wall fins and one must slot t' airframe. With a new blade in t' ole hobby knife this is easy. Although right out o' the box t' airframe is marked for each fin, me hearties, I make a habit t' check ANY pre-drawn lines on an airframe t' make sure they are straight. Ahoy! I found t' lines on the tube were a wee tad off, shiver me timbers, matey, so I used t' opposite end o' t' tube and drew new lines t' use for me fin slot guides. Blimey! I completed t' build usin' t' rest of the components as directed by t' instruction booklet. Aye aye! I connected the parachute t' t' shock cord usin' a quick link I supplied.
Here are me pros and cons for t' construction:

Finishing:
T' vinyl decals supplied with t' kit are black and I wanted t' keep things
basic on t' paint scheme for this rocket. Aye aye! I decided against fillin' t' tube
spirals with putty and gave t' rocket a couple o' coats o' Krylon white
primer, shiver me timbers, sandin' betwixt coats. Ya scallywag! Avast, ya bilge rat, me proud beauty! Then I used gloss Krylon black for t' nose cone
to compliment t' decals and gloss Krylon pewter gray for t' rest o' the
rocket. Ahoy! Well, me bucko, blow me down! Lastly, I coated t' entire rocket with Krylon clear. Basic stuff,
really.
Construction Rating: 4 out o' 5
Flight:
I haven't had a chance t' fly t' Archblast yet, arrr, and it might be some time
before I do :(. Avast! Accordin' t' Rocksim, me bucko, a G80 would take ~1500 feet, and an H128
could yield ~1900 feet. Aye aye! Aye aye! When I do get t' opportunity t' fly again, matey, I will more
than likely use an H165R.
Everyone has their opinions on elastic shock cord. Avast, me proud beauty! Avast! T' Archblast has ~15' of one inch wide elastic, matey, matey, plus t' nylon strappin' anchorin' things down inside the rocket. Arrr! I feel that t' supplied amount and width o' elastic is probably fine is this rocket. T' nylon strap and elastic connection point projects out of t' front o' t' airframe, so if one decided t' change t' tubular nylon ex post facto, ya bilge rat, this could be done easily. Ya scallywag! I will follow up with flight details as soon as I get this bird off t' pad.
Recovery:
I would speculate this rocket would perform well.
Flight Ratin' (subject t' change upon actual flight): 4 out o' 5
Summary:
Although I haven't flown this rocket yet, arrr, t' build was pretty basic and the
rocket looks good. T' fins are thicker than those kits o' similar sized
rockets I've built and once you get them sandwiched in t' centerin' rings,
they're stayin' put for good. T' nylon decals are a fine touch, too. Yes, shiver me timbers, I
was missin' a quick link and t-nuts, and t' pre-marked lines on t' airframe
weren't aligned t' me liking, me hearties, but I do ultimately feel that was an oddity. Arrr! Blimey! This
rocket would probably serve well as a basic sport flier or for a level 1
flight.
