Which confirms my strong opinion that add ons, like a crowbar induce extra
risks.
Regulators are more reliable then regulator/crowbar combinations. I
further strongly disagree that keeping resetting any CB is harmless. There
are warnings about this in any "learn to fly" book. In this case every
time the cb blows, it has hit the circuit with some large current. This
reocurrent short circuit will harm every component involved, and could
bring further harm, leading to disaster.

OK that makes sense -
So having closed the wing you then have to take off the ailerons to
post-cure them - I assume that is it possible to reattach them (albeit a bit
fiddly) and specifically the aileron link rod through the inspection hole??
Or did you post cure and finish your ailerons prior to closing the wing?

Hi Will,
It sounds risky. I know builders that have done it without the upper
skin but then you need to build up exactly same height in order to
"simulate" the skin, if you are using the template.
I did set the wing incidence before the uni reinforcing plies. The
template sits more accurate on the wing without uni.

Stephan

My next task is to set the wing incidence.
Can one do this with the wings still open? - in other words, without
the
upper surface and the uni reinforcing plies?
Any tips/bright ideas as to how to make this task easier...

Use beer cans, when empty flush out, run a sharp knife round the middle
leave to dry.Instant one shot mixing cup, ok a bit rough edged can clean
up
with scissors if you want.
To get you started get in a batch of your favourite brew and some mates
around drinking and telling lies to each other, soon have a ready pile.
This approach allows you to argue successfully that you are saving heaps
of
money by not squandering it on purpose made mixing cups.

Will, and everyone
Don't forget the incidence of the wings is more critical outboard than it is at
the root.
Set it up on the port wing and let cure as described but then set up the second
wing to be identical incidence at the flap/aileron junction. This will help to
avoid any built in roll tendency

Hi Will,
I post cured flaps, ailerons, ruder and tail plane after the wing
closing.
Attach the link rod wing side before closing. The link rod will snap on
after the aileron is attached. Check the movement of link rod before
closing so this can be achieved.
It is very easy to attach/detach the aileron after upper skin is on. In
fact
I would recommend taking them off. It is much easier to work the
wing/fuselage without them.
This is my technique how to install the aileron: Use strings, diameter
of 1 mm or so, one for each hinge. At the end of each string you attach
a small washer (not too heavy). Pull the string through hinge and the
wing surface.
Now, when you tighten the string hinge will get in position and you can
screw in the bolts. You need three hands for this and the third hand is
your mouth. You put the string in the mouth and tighten it by moving
your head
:-)
It sound stupid, and probably looks stupid, but it works very well after
some practice
Good luck
Stephan

Hi Graham,
You are of course right.
I did check the incidence at the position (more or less) that you
describe (I read your tips in the "Hints and Tips") and it shows same
reading on both wings. But I measured the thickness at the same position
and they were different: about 8 mm or so. I.e. the wings are not 100%
symmetric.
My conclusion was: do it per manual as correct as possible and do the
"Graham check" before mixing the Araldite 420. If God is on my side it
will work ok. Otherwise I have to trim.
Regards,
Stephan

Hi,
The definate answer is the fact you have the trim wires and Com lead
running together, split them so they are as far apart as you can get them.
Chances are, you will also be able to hear the trim servo running through
your headset ?
Cheers,
Nev.
