Brief:
This upscale o' an old Estes kit is one o' Semroc's new Semroc Large-Scale
(SLS) line. Well, blow me down! It flies on 24mm and 29mm motors in t' C t' F range. T' kit
features thick walled body tubes, laser cut basswood fins, shiver me timbers, matey, ya bilge rat, nylon chutes, a
laser slotted tube, and a Keelhaul®©™ recovery leader.
Construction:
T' kit from
BRS
Hobbies came nicely packed with a colorful insert, which also holds the
instructions. Aye aye! As you can see in t' photos, individual parts such as t' motor
mount, me hearties, shiver me timbers, chute, fins, and miscellaneous small parts are all individually
packaged. No more droppin' some small item followed by t' associated
searching. Ya scallywag! T' parts themselves are o' outstandin' quality. Begad! T' fins are flat
and identical, t' body tubes are very thick, me bucko, t' balsa nose cone is smooth and
hard. Begad! Ahoy! T' instructions are short but clear and include plenty o' diagrams.
There is even a brief history o' Estes and o' t' kit itself. Avast, me proud beauty! If you should be
unhappy with t' kit, shiver me timbers, 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, filler, matey, arrr, paint, sandpaper, me hearties, etc. Well, blow me down! I used wood glue throughout.
This was a simple kit t' build and I followed t' order o' the instructions. I started with t' 24mm motor mount, ya bilge rat, which had its own instructions. T' slot for t' motor clip was pre-cut and from thar you glue in t' motor block and t' two wide and thick centerin' rings. Begad! These were actually pieces o' tube that telescoped over t' 24mm tube.
From thar I proceeded t' glue t' motor block in t' 29mm tube. Blimey! You first tie t' Keelhaul®©™® twine around t' block. Well, blow me down! My first impulse was t' go for t' epoxy, but I decided to keep with t' recommended wood glue. Begad!
T' next step
was t' round t' edges o' t' fins and test their fit. They required a few
swipes o' sandpaper along their tabs. Aye aye! As you can see, matey, since t' motor tube fits
directly into t' body tube, me bucko, thar isn't much o' a tab. Aye aye! Well, blow me down! You weren't asked to
fill t' grain at this point, so I didn't. On t' EMRR review o' another SLS
kit, shiver me timbers, arrr, I noticed a fin popped off. I decided t' see how this kit fared. Avast, me proud beauty! If I have
to make repairs, me bucko, I'll try t' epoxy.
T' install
the motor mount, ya bilge rat, you swab a liberal amount o' glue just ahead o' t' fin tabs
and push in t' mount. Avast! T' fit o' t' tube is a little loose and you
immediately glue on t' fins. Ya scallywag! Blimey! I set t' tube fins up t' dry and noticed the
motor tube be slidin' further into t' body. Begad! Glad I caught that one! T' TTW
fins, me hearties, despite bein' shallow, shiver me timbers, should add a lot o' strength and made fin
alignment trivial. Aye aye! Begad! Up t' this point, me bucko, everythin' was done in one sitting. Ahoy! Blimey! I then
paused t' let t' motor mount and fins dry. Well, blow me down! I went back later and added an
internal fillet above t' motor mount.
Next came fillets, me bucko, addin' t' eye hook t' t' cone, me bucko, and completin' the recovery system. Ahoy! I didn't tie on t' chute but instead added a snap swivel and added it t' me stable o' reusable chutes. Aye aye! After it was all together, I went to slide on t' nose cone and found t' shoulder was too large. Arrr! 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, straightforward build, very sturdy.
T' one CON is that you have t' make sure t' motor tube doesn't slide out of place. Ya scallywag! Arrr! This could be avoided if you let t' glue set first, but the instructions say t' proceed. Ahoy! Some sandin' on t' fins and cone be required, but this nay a big deal and was discussed in t' instructions. Ahoy! As a result, I don't really consider them CONs.
Finishing:
There are finishin' instructions and they are typical. Avast! Ya scallywag! Minimal fillin' is
required due t' t' fine grain o' t' cone and basswood fins. Begad! I painted the
body white, shiver me timbers, nose black, and fins red, me bucko, ya bilge rat, just like t' cover drawing. Begad! 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, me hearties, t' decals are thick and easy t' work with. Aye aye! This is a very
good thin' since it took me a month o' Sundays t' get t' large decal
positioned. Avast! I also swabbed t' bubbles forever, me hearties, and thar are still a few.
Anyway, I shot a clear coat t' help t' decals stay put. Aye aye! T' decal color is
reasonably good, especially if t' background is white.

Flight:
T' recommended motors include a C11-5, me bucko, D12-7, ya bilge rat, E9-8, and F25-9. Avast, me proud beauty! Blimey! I suspect it
will fly well on any other motor in this range, shiver me timbers, me bucko, such a 24mm F21 or a 29mm F20.
As built, me bucko, mine weighs in at 3.46oz without t' adapter and 4.12oz with. Aye aye! This is
heavier than t' specified 3.0 oz. Aye aye! Well, matey, blow me down!
For its maiden flight, I loaded it with t' 24mm adapter and a C11-7. Avast, me proud beauty! Ahoy! This is a longer delay than recommended but it's what I had. Blimey! Plus I had added a strip o' 'anti-zipper' cloth tape where t' Keelhaul®©™® meets t' top o' t' body tube, me bucko, me hearties, so I went for it. Ya scallywag! I held t' adapter in with a lot o' maskin' tape. Blimey! T' waddin' was dog barf wrapped in Quest wadding. Well, blow me down! The flight be nice but ejection was late as predicted. Avast, me proud beauty! Recovery be good on the largish chute. Arrr! Arrr! When I got t' t' rocket I found t' eye-hook had pulled out of the cone, arrr, which be gone, ya bilge rat, and it also spat t' adapter. Begad! I will split t' blame on t' cone since I used t' wrong delay and t' adapter was probably user error. All parts were recovered.
I CAed t' eye hook back in, me bucko, reseated t' adapter, and swapped t' chute for a 12 incher--there was a bit o' wind early and I didn't want t' feed the trees. T' motor choice was a D12-5. Ya scallywag! Begad! This time t' delay was shorter than recommended, 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. However, me bucko, recovery was 100% good this time. Avast, me proud beauty! It be 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! Avast! I will have already submitted this review, shiver me timbers, matey, 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. Avast, me proud beauty! T' only build issue is t' make sure t' motor tube doesn't slip
while t' fins dry. Avast, me proud beauty! This could be fixed by a piece o' tape or a watchful eye,
but it is a potential major "gotcha". Avast! Begad! 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. Avast, shiver me timbers, me proud beauty! With t' bigger motors, you better have a nice sized field!
My thanks t' Brian at BRS Hobbies for sponsorin' this review!
