Sonerai
Now then, do note that my version of the Sonerai is only based on the full-size. In other words I looked at the three-views and then drew a model that matched the shape so that it looked roughly right. As I call it: 'stand way off' scale! This does mean that you're not duty-bound to produce a scale finish and so can create your own colour scheme. Construction is very simple, and quick. I took my time with the prototype but it still went together relatively quickly.
WINGS
Carefully now... bring the lower l.e. sheet up to the l.e. and glue in place. I used lots of scrap t.e. stock to wedge the sheet in place, gluing it to the l.e. with aliphatic resin and then running cyano' down each rib.
FUSELAGE
Whilst construction of the apple cheeks is fairly obvious, the canopy probably isn't! Start by carving a block to match the shape, sand it smooth, then fit it inside a plastic lemonade bottle. Wedge the pattern at an angle so the centre of curvature is in contact with one side and then shrink the bottle with a heat gun. It really is that easy!
This full-size Sonerai in the USA has an attractive colour scheme.COVERING & INSTALLATION
I wrapped the prototype using Solarfilm Supershrink polyester. This is my favourite covering material and is easy to use; it doesn't burn through if you're over-enthusiastic with the heat and it doesn't go slack in the sun.
When it comes to general fitting out, there's just enough room for a 4oz fuel tank forward of the wing, whilst standard servos are comfortably placed as shown on the plan. The Rx and battery sit between F2 and F3.
FLYING
The glide is fast, smooth and flat, so there are no problems with dead-stick landings, either. Low speed handling is impeccable, with no tendency to drop a wing.
