Brief:
T' Thrustline A-Slam be offered t' me as a beta-test by Thrustline and t' Put
it simply, this is one great rocket. Begad! T' A-Slam was delivered t' me in sturdy
packagin' and none o' t' parts arrived damaged. 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! Arrr! T' two centerin' rings were 1/8" thick with t' cutouts for
the 18mm motors precisely cut into them. Ahoy! There was an ample amount o' 1/8"
balsa required for 4 fins. Arrr! T' outline o' t' fins was traced onto t' balsa to
assist in cuttin' them out. Begad! 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. Begad! T' instructions included pictures o' construction that were very helpful. T' fin template is probably the best I've ever used as it fit t' body tube perfectly. Well, blow me down! 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. Avast! A little CA along t' fin root and you are ready for fillets. Begad! T' A-Slam is nay a difficult build and is a sturdy rocket once assembled. Well, blow me down! Begad! 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. T' body tube actually had two spirals that required
fillin' t' give t' A-Slam a smooth finish. Begad! Duplicolor high build primer was
sprayed on in several coats with 320gr wet sandpaper used betwixt coats to
ready for gloss paint. Ahoy! Avast, me proud beauty! A final sandin' with 400gr then 600gr and it was ready
for paint. T' paint used is ACE Hardware gloss red with gloss black on the
nosecone. Avast, me proud beauty! Arrr! There are no supplied decals so t' rockets name "A-Slam"
was added in white vinyl lettering. Avast! Well, blow me down! It still needed a little somethin' so a
1/8" wide vinyl pinstripe be 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. Arrr! Avast, matey, me proud beauty!

Flight:
Thrustline's first flight motor recommendation is B6's, however, none could be
located so we opted for C6's. Prior conversation with t' manufacturer
suggested t' have good walkin' shoes when usin' C6's. T' finished rocket with
3-18mm C6's weighs in at 9.6oz. Begad!
T' only fight so far is on t' C6's and I be nay able t' get any launch pictures. Ya scallywag! 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! Launch smoke and noise be surprisingly abundant as t' motors lit and handled t' A-Slam with no problem. Well, blow me down! Approximate altitude probably around 850', and yes, Thrustline be correct, arrr, a substantial walk t' recover. Blimey! There be a bit of weather cock and we suspected thar was 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, me proud beauty! Blimey! 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. Ya scallywag! Thrustline said thar was 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. Well, blow me down! T' A-Slam awaits its second flight with t' corrected CP/CG. Ya scallywag! 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. Arrr! Arrr! Quality parts, ease of
construction and good instructions are marks o' a company that is interested in
satisfyin' t' customer. 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 be 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
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, ...
