Moving on to the wing supports,
New adventures in waterforming! (My Dad's suggestion, inspired by how they used to build the old square-riggers

)
A concern on this model template, there are no supports for the wings in the template!


Even without my modifications I cannot see how one could avoid "nacelle droop" without supports!
You could use the method below or maybe some card supports.
So, to add some support (also as I have increased the weight due to the LEDs) I took some coffee/popsicle sticks and tried to get the angles right. I measured where the wing starts and then soaked the stick in some water. Remove, bend as far as you can (gently!) then repeat until you get your angle right

If you do take it too far then (as long as the stick is still wet) you can just reduce the angle.
Once you've got your angle the sticks need to dry in shape. I did one, matching the angle to the wing, then used it to assist lining up the second one. I clamped them together to ensure both match. Here we go....
Finished product
And test fit into the secondary hull, I cut some holes to allow the stick to be threaded through. I suppose you could use individual sticks, depending on the model and what effect you're after.
