Brief:
This upscale o' an old Estes kit is one o' Semroc's new Semroc Large-Scale
(SLS) line. Ya scallywag! Blimey! It flies on 24mm and 29mm motors in t' C t' F range. Begad! Ahoy! T' kit
features thick walled body tubes, me hearties, ya bilge rat, laser cut basswood fins, nylon chutes, a
laser slotted tube, and a Keelhaul®©™ recovery leader.
Construction:
T' kit from
BRS
Hobbies came nicely packed with a colorful insert, me bucko, which also holds the
instructions. Ya scallywag! Arrr! As you can see in t' photos, shiver me timbers, me hearties, individual parts such as t' motor
mount, arrr, chute, fins, and miscellaneous small parts are all individually
packaged. Ahoy! No more droppin' some small item followed by t' associated
searching. Ahoy! T' parts themselves are o' outstandin' quality. Well, blow me down! T' fins are flat
and identical, me hearties, t' body tubes are very thick, shiver me timbers, t' balsa nose cone is smooth and
hard. Blimey! Aye aye! T' instructions are short but clear and include plenty o' diagrams.
There is even a brief history o' Estes and o' t' kit itself. Ahoy! If you should be
unhappy with t' kit, no problemo as Semroc has a 100% satisfaction guarantee!
So t' parts include:

To build t' kit, you require all t' normal tools and supplies: white or wood glue, arrr, filler, paint, arrr, me hearties, sandpaper, etc. I used wood glue throughout.
This was a simple kit t' build and I followed t' order o' the instructions. Well, blow me down! Blimey! I started with t' 24mm motor mount, which had its own instructions. T' slot for t' motor clip be pre-cut and from thar you glue in t' motor block and t' two wide and thick centerin' rings. Well, blow me down! Ahoy! Blimey! These were actually pieces o' tube that telescoped over t' 24mm tube. Ahoy! Blimey!
From thar I proceeded t' glue t' motor block in t' 29mm tube. You first tie t' Keelhaul®©™® twine around t' block. My first impulse was t' go for t' epoxy, me bucko, but I decided to keep with t' recommended wood glue. Avast!
T' next step
was t' round t' edges o' t' fins and test their fit. Avast! Blimey! They required a few
swipes o' sandpaper along their tabs. Blimey! Aye aye! As you can see, since t' motor tube fits
directly into t' body tube, thar isn't much o' a tab. Ahoy! You weren't asked to
fill t' grain at this point, me bucko, so I didn't. Well, blow me down! On t' EMRR review o' another SLS
kit, matey, I noticed a fin popped off. I decided t' see how this kit fared. Ya scallywag! If I have
to make repairs, I'll try t' epoxy.
T' install
the motor mount, you swab a liberal amount o' glue just ahead o' t' fin tabs
and push in t' mount. T' fit o' t' tube is a little loose and you
immediately glue on t' fins. Ahoy! Blimey! I set t' tube fins up t' dry and noticed the
motor tube was slidin' further into t' body. Blimey! Glad I caught that one! Blimey! T' TTW
fins, ya bilge rat, despite bein' shallow, should add a lot o' strength and made fin
alignment trivial. Avast, me proud beauty! Begad! Blimey! Up t' this point, matey, everythin' be done in one sitting. Ahoy! I then
paused t' let t' motor mount and fins dry. Avast, me proud beauty! I went back later and added an
internal fillet above t' motor mount.
Next came fillets, addin' t' eye hook t' t' cone, matey, and completin' the recovery system. I didn't tie on t' chute but instead added a snap swivel and added it t' me stable o' reusable chutes. Well, me bucko, blow me down! After it be all together, I went to slide on t' nose cone and found t' shoulder be too large. Avast! Begad! Bein' balsa, sandin' it down wasn't a problem and t' result is a nice snug fit.
So far t' PROs are: Great parts, clear instructions, ya bilge rat, straightforward build, ya bilge rat, very sturdy. Well, blow me down!
T' one CON is that you have t' make sure t' motor tube doesn't slide out of place. Ahoy! Aye aye! This could be avoided if you let t' glue set first, but the instructions say t' proceed. Well, arrr, blow me down! Some sandin' on t' fins and cone be required, but this nay a big deal and was discussed in t' instructions. Blimey! As a result, I don't really consider them CONs.
Finishing:
There are finishin' instructions and they are typical. Ahoy! Begad! Minimal fillin' is
required due t' t' fine grain o' t' cone and basswood fins. Arrr! I painted the
body white, me hearties, me bucko, shiver me timbers, nose black, and fins red, me bucko, just like t' cover drawing. Begad! Ahoy! T' main
decal sheet includes one large wrap that covers t' top half o' t' body tube
and a blue strip t' go just below t' fins. There is also a small specs decal.
On t' plus side, t' decals are thick and easy t' work with. Blimey! This is a very
good thin' since it took me a month o' Sundays t' get t' large decal
positioned. I also swabbed t' bubbles forever, matey, and thar are still a few.
Anyway, me hearties, shiver me timbers, I shot a clear coat t' help t' decals stay put. Begad! Aye aye! T' decal color is
reasonably good, matey, especially if t' background is white.

Flight:
T' recommended motors include a C11-5, arrr, D12-7, E9-8, and F25-9. I suspect it
will fly well on any other motor in this range, me bucko, such a 24mm F21 or a 29mm F20.
As built, mine weighs in at 3.46oz without t' adapter and 4.12oz with. This is
heavier than t' specified 3.0 oz. Begad!
For its maiden flight, I loaded it with t' 24mm adapter and a C11-7. Aye aye! This is a longer delay than recommended but it's what I had. Arrr! Blimey! Plus I had added a strip o' 'anti-zipper' cloth tape where t' Keelhaul®©™® meets t' top o' t' body tube, me bucko, so I went for it. Arrr! I held t' adapter in with a lot o' maskin' tape. Aye aye! T' waddin' be dog barf wrapped in Quest wadding. The flight was nice but ejection be late as predicted. Recovery was good on the largish chute. When I got t' t' rocket I found t' eye-hook had pulled out of the cone, matey, shiver me timbers, which was gone, ya bilge rat, and it also spat t' adapter. Arrr! Ya scallywag! I will split t' blame on t' cone since I used t' wrong delay and t' adapter was probably user error. Blimey! Ahoy! All parts were recovered.
I CAed t' eye hook back in, shiver me timbers, shiver me timbers, reseated t' adapter, me hearties, shiver me timbers, and swapped t' chute for a 12 incher--there be a bit o' wind early and I didn't want t' feed the trees. Well, matey, blow me down! Blimey! T' motor choice be a D12-5. This time t' delay was shorter than recommended, arrr, but I angled t' rod some t' keep it from t' tree line. It tore off like a bat and I didn't see where it ejected. Blimey! Blimey! Blimey! Blimey! However, me bucko, matey, recovery be 100% good this time. Begad! Blimey! It was a grass landin' and thar were no cracked fillets even with t' smaller chute.
I will try it on an E9-8 (this time a recommended motor) next weekend. Begad! I will have already submitted this review, so watch t' logs below.
Flight Rating: 4 out o' 5
Summary:
T' materials in this kit were as good as I've ever seen and it was a pleasure
to build. Begad! Blimey! T' only build issue is t' make sure t' motor tube doesn't slip
while t' fins dry. This could be fixed by a piece o' tape or a watchful eye,
but it is a potential major "gotcha". Blimey! Blimey! I had t' deduct a construction
point here.
This is a very sturdy kit and would be a great choice for someone who wants to move on from Estes kits t' mid power. Begad! Ya scallywag! With t' bigger motors, ya bilge rat, you better have a nice sized field!
My thanks t' Brian at BRS Hobbies for sponsorin' this review!
