British control horn rigging query.

[kajones1644]

After a 25 year absence the WNW range of models has wet my appetite to return. I am planning on starting with either the Pup or SE.5A. I hope that someone can guide me as to the best method of control horn rigging, specifically aerilon/tailplane as this requires two sets of rigging. Fuselage to control horn and then horn to control surface. The control horns seem to small to fix two sets of control wires using the methods often mentioned in this forum.

Any advice please?

Hi and welcome to the forum, KA.  Actually, it isn't all that hard
at all.  Of course you can't pull too hard on the plastic "eye" on the
control horn, it is pretty easy to slip a line through a brass tube...I
usually use 0.5mm tube...then through the control horn and back
through the brass tube.  Nothing to it.   Here's a picture of
one I did...sorry not too clear but hopefully will give the idea.



Hope that helps .

Cheers,
Ernie

Ernie. Thanks for the quick response. How are you fixing the control wire from the back of the horn to the tailplane? That the one I am struggling with. Nice pic btw.

Hi Keith.  Regarding the rear lines to the elevators, I took the easy way
out and just ran the line through the rear hole, from outside to inside and put
a wee drop of CA on...I use a sewing needle with the eye half snipped off
which delivers just a tiny droplet of glue. after set, just snip off the excess on
the rudder-side and job done.  Once one end is done you can do the same on the
under side tightening the line as required on that end.  The line just goes through
the hole in the elevator, so it is just one continuous line.  What you could do if you
like is simulate a connection where the wire goes through the elevator by running it
through a short piece of 0.4 or 0.5mm tube.  The glued ares at the control horns are
pretty much invisible.

Cheers,
Ernie

I usually drill a 0.3mm hole through the control horn, this is large enough for the two control cables to pass through, I use 0.12mm line for my rigging on a 1:32 scale model. I always connect the front line first passing the line through the hole then doubling back through a short length of 0.5mm brass tube, I tension the line then add a small drop of CA. I then do the rear line. I do this by drilling a hole through the control surface, I connect the line to the bottom control horn using the same 0.5mm brass tube method, then I pass the line through the control surface (rudder, elevator or aileron) and connect it again using the same method. Do not over tension the line you are using as there is a possibility that the control horn will break unless of course you are using PE control horns which are very strong.

Guys
Thank you for the helpful tips. Kinda in line with what I was thinking but good to have confirmation.
