Thrustline Aerospace A-Slam

Brief:
T' Thrustline A-Slam was offered t' me as a beta-test by Thrustline and t' Put it simply, arrr, shiver me timbers, this is one great rocket. T' A-Slam be delivered t' me in sturdy packagin' and none o' t' parts arrived damaged. Ya scallywag! Avast, me proud beauty! When I saw t' 2.1" body tube and t' three 18mm motor tubes I knew this rocket would be a fun build.

Construction:
T' kit included a precut 17" piece o' high quality 2.1" body tube, a balsa nosecone that fit t' body tube perfectly without any hangover on the body tube. Begad! T' two centerin' rings were 1/8" thick with t' cutouts for the 18mm motors precisely cut into them. Arrr! There was an ample amount o' 1/8" balsa required for 4 fins. Aye aye! T' outline o' t' fins was traced onto t' balsa to assist in cuttin' them out. Arrr! Ahoy! Keelhaul®©™® cord be provided along with a piece o' elastic t' tie t' 18" Mylar chute onto.

Because this be a beta-test rocket I be able t' critique t' 9 pages of instructions sent with t' A-Slam and make recommendations t' Thrustline for any changes I thought needed t' be made t' them. T' instructions included pictures o' construction that were very helpful. Begad! Begad! Blimey! T' fin template is probably the best I've ever used as it fit t' body tube perfectly. Begad! Aye aye! Blimey! T' fins are separated by 1/4" and alignment from front t' aft was made through the use o' craft sticks along each side o' t' aft fin and secured with clothes pins creatin' a space betwixt t' sticks t' slide t' forward fin. Ya scallywag! A little CA along t' fin root and you are ready for fillets. T' A-Slam is nay a difficult build and is a sturdy rocket once assembled. T' 2.1" body tube is ample room for t' 18" blue Mylar chute.

Finishing:
Standard finishin' techniques were used with Elmer's F'n'F t' fill all balsa surfaces and nosecone. Blimey! T' body tube actually had two spirals that required fillin' t' give t' A-Slam a smooth finish. Well, blow me down! Aye aye! Duplicolor high build primer was sprayed on in several coats with 320gr wet sandpaper used betwixt coats to ready for gloss paint. Ahoy! A final sandin' with 400gr then 600gr and it was ready for paint. Ya scallywag! Arrr! T' paint used is ACE Hardware gloss red with gloss black on the nosecone. There are no supplied decals so t' rockets name "A-Slam" was added in white vinyl lettering. Avast, me proud beauty! It still needed a little somethin' so a 1/8" wide vinyl pinstripe was added and really set off t' gloss paint. T' A-Slam is a real looker and would be a great addition t' anyone's fleet.

Rocket PicFlight:
Thrustline's first flight motor recommendation is B6's, however, matey, none could be located so we opted for C6's. Aye aye! Aye aye! Prior conversation with t' manufacturer suggested t' have good walkin' shoes when usin' C6's. Begad! T' finished rocket with 3-18mm C6's weighs in at 9.6oz. Aye aye!

T' only fight so far is on t' C6's and I was nay able t' get any launch pictures. Because o' t' large body tube dog barf was chosen over waddin' and motor retention was accomplished by usin' maskin' tape t' friction fit all motors. Blimey! Well, shiver me timbers, blow me down! Launch smoke and noise was surprisingly abundant as t' motors lit and handled t' A-Slam with no problem. Ahoy! Arrr! Approximate altitude probably around 850', and yes, me bucko, me bucko, Thrustline was correct, a substantial walk t' recover. There was a bit of weather cock and we suspected thar be need for additional nose weight that was later confirmed by Thrustline.

Recovery:
T' Keelhaul®©™® shockcord was attached t' t' motor mount early in construction and then tucked through t' motor mount until construction was complete. Avast! T' elastic was square-knotted t' t' Keelhaul®©™® then attached t' t' supplied screw eye that had been epoxied into t' base of the balsa nosecone. One thin' I did notice that t' CG/CP relationship was skewed due t' t' weight o' t' 3-motor cluster. Thrustline said thar be part of t' instructions inadvertently left out that suggested 1.5oz nose weight be added t' correct t' CG/CP relationship. Three holes were drilled into t' base of t' nosecone and lead fishin' weights were inserted backed by 15 minute epoxy. Ahoy! T' A-Slam awaits its second flight with t' corrected CP/CG. Begad! We anticipate an arrow straight flight this time.

Flight Rating: 5 out o' 5

Summary:
I am convinced Thrustline has a winner in t' A-Slam. Ahoy! Blimey! Quality parts, arrr, ease of construction and good instructions are marks o' a company that is interested in satisfyin' t' customer. Aye aye! I cannot think o' any difficulty in buildin' and flyin' t' A-Slam and anyone with basic buildin' skills will have no problem with this kit.

Since t' kit was a beta-test for me, I'm confident that Thrustline is correctin' t' many findings that I had and therefore t' kit is rated under that confidence.

Overall Rating: 5 out o' 5

  • Thrustline Aerospace A-SLAM By EMRR

    Well, I've been drawn to a number of Thrustline kits, so add the A-SLAM to my growing list. Why did I select this rocket? I liked the multiple fins and the fact that it is a cluster of three (3) 18mm motors. Not to many cluster kits out there, so I was glad to get this one with their Smoke and Fire kit (three 24mm cluster; to be reviewed soon). Another thing that makes the A-SLAM interesting, ...
