You'll also see a bit of hook and loop (not included) which we use
to hold the battery securely in place.
Control horns, servo & pushrod installation
Although you can install
the servos and control
hardware after covering
your Minuette, we find
it easier to temporarily
mount everything in
place before covering.
This way you have
unblocked access
inside the fuselage
and wings to get the
servos, extensions, and
pushrods in place.
These photos shown examples
of servo installation in one of the
Minuette prototypes. As you can
see, we've used Dubro's 2-56 pull-
pull setup for the elevator and
rudder and it works very well. You
can use other systems, but a pull-
pull system will look best as it's more "period correct".
We used some of the leftover 3/16" sq. basswood to form the servo
mounting beams inside the fuselage.
Servo Hatches (H5)
Located on LP5 are both H5s. These
hatches are attached to the top and
bottom of the fuselage, covering the
servo bay. Using the H5s as a guide,
use a 1/16" drill bit to drill through the
H6 and H7s already installed.
Then use four 2-56x3/4” self tapping screws to hold on each of
the hatches.
Tail Surface Control Horns (CH1)
As I mentioned up-front, included in the
Minuette are laser-cut control horns, cut from
3-layer plywood - CH1s from LP8.
Although I have not had this happen with
any of the prototypes, I will admit that it is
possible to break off these horns with rough
handling, hangar rash, or just plain bad luck.
To repair them would involve having to
remove the covering and add wood to form
the "seat" for a conventional control horn
(not included).
Using CH1s and wicking in thin CA to reinforce
the ends works perfectly fine and will last a
long time - as long as you take care in the
storage and transportation of your Minuette.
If you choose to use them, these will fit into
the pre-cut slots in the rudder, and into one
of the elevator halves. Make sure it's inserted so it's equal on both
sides, not cocked to one side or the other.
Lastly, using a bit of thin CA, wick it in all around the ends of CH1.
This will strengthen them even further.
Aileron Hatches (SH1)
When mounting the aileron
servos to each of the SH1's you'll
need to cut a few 3/4" lengths of
the 3/16" sq. basswood scrap.
Make four thicker mounting
posts by laminating two pieces
together then sand the ends flat.
Position your aileron servo on
the inside of the aileron hatch so the
servo arm output shaft is centered in
the opening.
On the inside of each aileron hatch,
glue one post on each side of the
servo as shown in the photo.
Note that the left hatch is a mirror
image of the right hatch.
Now fit the servo hatches into position
on the bottom of the wing. Using the pre-cut holes as a guide,
drill four 1/16” mounting holes into the basswood mounting posts
you just installed. Harden the wood with a bit of thin CA and you
can use the supplied 2-56 x 3/4” self tapping screws to secure the
hatches in place.
Finish the layout of your radio gear by adding the receiver, flight
pack battery, ESC, and the switch (if using one). We mounted the
receiver to the tray by using a bit of self-adhesive hook-and-loop
(not included). The ESC was mounted to the inside wall of the
fuselage in the battery area.
Covering
Now it is time to cover the Minuette. Remove the power-plant,
main gear, pushrods, and any other components that would get in
the way of applying the covering.
Double check that all surfaces are smooth and ready to cover. Sand
as necessary, then cover the entire airframe with the covering/finish
of your choice.
To cover the Minuette as shown in our prototypes takes a complete
2 meter roll of covering, carefully cut and used.
When the covering is complete, re-attach all the components you
removed earlier in this step.

If you want to use graphics similar to the ones we used, Old School
Model Works has teamed up with Callie
Graphics as a supplier for pre-cut vinyl.
They are a very well known provider of
custom graphics for R/C models.
We have supplied them with the artwork
needed and you can order straight from
them, choosing the colors that work for you.
