Use 5min epoxy in case you ever want to fly it on anything larger. They fly
great on small H's.

Contrary to the first four replies to this post, I think yellow glue will
be fine, surface mount fins notwithstanding.

I used almost nothing but yellow glue on a LOC IV and I have flown that on
Hs several times.  Properly done, the glue joint will be stronger than the
tube or the plywood.  I'd suggest rivet gluing--drilling small holes under
the fin, then using the two step process described in the FAQ.  Then
fillet, and fly high!

Using 5 min epoxy throughout, and built to the instructions, it will
survive any motor that will fit in the motor mount. This includes H125
and H500.

I have to agree with you, I have several rockets that fly on motors up to G
that wood glue was used to attach the fins. Have yet to have a fin come lose.

An E15 works OK too, but here's some of the options for "more":

The F20-7 Econojet will take it to about 3100 feet.  
Or try the NCR F62-6 to about 3300 feet. (my personal favorite).  
Or the AT F25-9 to about 3700 feet (Mike, did you mean this or the F20 EJ?)  
Or try an AT G40-10 to about 4500 feet, or even  an H128-14W RMS to about
4700 feet.

Or, you may want more :-)

Hello,
       Can I use Elmers Yellow Wood Glue to constuct my lil nuke? I'll be
flying it on aerotech E engines. Please let me know, I am thinking about
getting it and the motor mount adaptor to fly on E's.

I would not build it with wood glue.  Since it has surface mount fins it
really needs to be made with epoxy.  (B.Kaplow may jump all over me at this
point)  I would glue the fins on with 5 min Epoxy and then fillet them with
30 min. I would also use 30 min to build the rest of the rocket.  I don't
think you will be able to find any Estes E motors as these have been
discontinued for about 2 years.  It flies very well on Aerotech E30-7,
F50-9, and F20-7.  The Nuke is one of my favorite kits and I have at least
10 Fmotor flights on mine, and a bunch of Es as well.  Please ignor my
comment about Estes Es if you have a supply of them (they are rather prone
to CATOS). Make sure you sand the shiney surface off the tube where you
attach the fins.

You need atleast 5 Minute Epoxy,but try wood glue and fly it on a D12-3 first
flight and see if the fins hold on.But dont count on it....

One of my favorite kits. Use 5 min epoxy to mount fins and I also used 5min for
the fillets. Little tricky though. I have about 15 flights on my model without
even a scratch. Built right, this is a tough rocket. Try flying on a F25
Econojet. Great motor for that rocket. Also, I flew mine on a F22j -5 today.
Great flight. E 30 is fine for a small field, but I think you will want more.

Wood glue is fine. Silent built a Binder Spike and certified Level I
using an H128 (I Think) and he used wood glue. Do you sand your Estes
style body tubes before attaching the fins? Do the same with the LN.
Sand the glossy finish off the tube where the fins will joint, use
double glue joints, fillet well, and enjoy your Lil Nuke as it'll weigh
in lighter than the epoxied ones. Or not. Your choice.

Pay Forward,
Jeff

As you can see you said Aerotech.  I am loosing what little brain power I
had left.  I didn't mean to sound superior (god knows I'm not)  I hope you
have fun with the Nuke.  I would caution against using 5 min Epoxy for
motor mounts (I ruined a Vulcanite BT and MT once)  30 min gives you more
working time sliding the mount in in case you hit a snag (I did dry fit the
thing, I still don't know what I did, but I remember the sick feeling when
I could feel the Epoxy heat up, and the mount was not in the proper place)
Epoxy has other benifits besides strength.  You can make much nicer fillets
with it as it is runny and will make very nice smooth shapes.  I am making
a stretch Little Nuke that has a 54mm mount it will be glassed and I hope
to fly it on an I 65 or something bigger..........

                                V.T. Yours,

D.L.
I just completed and flew for the first time a 1.7 upscale of the Lil Nuke. 4
in dia by 50 inches which weighs 3.5 lbs fully loaded. What a cool looking
rocket. Put a 38 mil mm in it. Today I flew it for the test flight on a
H180(using a PML motor adapter) . Perfect flight. Came off the pad fast and
straight with normal recovery.

Any of the carpenters grade yellow glues are perfectly adequate for just
about any rocket construction joint involving wood and paper. The materials
will fail long before the glue joint ever does. In fact yellow glues are far
stronger for this application than any 5-minute epoxy you might find out
there. Even medium CA would do better than 5-minute epoxy. I'd cut thru the
glassine surface of the tube, so that you're gluing the fin to the tube and
not its top layer, and be sure to use double glue joints to glue the fins
and launch lug on.

As I've pointed out before, my THOY Hornet (roughly equivalent to the
LOC Graduator) was built 100% with Titebond and has flown on motors up thru
the H238. Of course it was modified with the third centering ring, baffle
ejection, and Kaplow Klips.

Now for another contraversial topic. IMHO, the Lil'Nuke is one of the most
marginally (un)stable LMR/HPR kits on the market. Beginners glob a ton of
5-minute epoxy into the motor mount, making this condition even worse. The
fins are just too small. Add that to the trend of folks cramming an H180
reload into rockets that were designed for disposable Fs and you can get
some really eratic flights. If I had this kit, I'd do one or more of the
following:

1) Make the fins significantly bigger. Maybe adding a 4th identical fin
would be enough.

2) Significantly lengthen the body tube. The LOC nose cones are very heavy,
and this gives it a biger lever arm to move the CG forward of the CP.

3) Add LOTS of nose weight.

4) Agree to never fly it on big (i.e. heavy) motors. One way to do this
would be to replace the 29mm MMT and centering rings with 24mm. That would
save the weight of the adapter, and make the rocket just a bit lighter.

Regardless of what you do, be sure to get VCP or some other tool, compute
the CP of the rocket as you build it, and MARK THE ROCKET. ALWAYS check for
1 caliber stability before you 'nuke someone with this one.

And of course, include Kaplow Klips on this and any rocket of this size.
