Wings
Wings require patience and time to build them. Thanks to their constant chord shape they are not complex to build. In addition as the airfoil has a flat intrados, you don't need any "cale" during the construction.
But installing engine mounts, floats, winglets, flaps... require a lot of careful work.
 Although the plane will fly very well without it, the flaps add a very nice scale touch. They also give the possibility to make very short landing. Which is quite spectacular.
Unless you adapt some exisitng hinges, you have to machine 8 pairs of hinges for the flaps. I've made them out of epoxy board. A CNC milling machine will be a great help to build them.
Each aileron is controlled by a servo (Hitec HS81). Flaps are controlled using only one servo that drive a main shaft as on the original plan.
