Article http://www.rcfair.com/blogs/view_entry/13480/ I received some comments with complaints that it was too complicated. Then, I remembered that someday I had built such model of airplane that anyone, who once worked with foam, would be able to copy. I decided to put it on public, in order to help someone in their hobby.In my opinion, the plane must look as a plane. A stick with wings is not my idea of a plane. I chose An-28. I downloaded very simple drawings, three views. It was enough for me, the rest is done in the mind:)I have a few pictures, because I haven't shot all the process. What I have I will show you. The technology is quite common. The structural frame is made of stringers, the skin is made of foam. So, - I began to work. The strong frames are made of plywood. The rest are made of foam.



The wooden rulers are also used in the construction of the plane. Having paid much attention to the site of attachment of loading gear, I used plywood because there was no weight limit. The thing is to make strong structural frame. It will be the basis of the fuselage.I've made the rods from wooden skewers, splicing them with help of threads and glue. Bowdens are made from the cocktail sticks. The landing gear is aluminum, everything is spring-loaded. The nose landing gear is steering, and is controlled by the separate rod from the rudder servo. The structural frame was glued over by foam. Patterns were not applied, everything is done by feel.The nose is made from a piece of foam. The cab glasses are transparent plastic from packages. The fuselage was sanded and painted with water paints in Aeroflot style.The graphite pencil was used to draw pointing and hatches. Final stage, I used a transparent scotch tape to cover everything. This is a very handy thing.To make the transportation convenient, vertical stabilizer was made removable. I tried a lot of options, finely it worked out very well.The wing consists of three parts: the center wing section with engine nacelles and flaps, and two outerwing with ailerons. The technology is the same: stringers and foam. I used plywood to reinforce foam ribs in the places of engine nacelle mounts. The bracing of wings is made of halves of the wooden ruler. On the photo everyone can see power cables from the battery (the battery is in the fuselage).ESCs are installed in the engine nacelles, to be cooled by an airflow. In my case, it looks like didn’t heat much.The engines in the photo turned out to be large and I put two 2830 200W motors. Hoods are made of plastic bottles, as usual. I tell you a secret - I didn't make a block of the hood for this plane. I used a suitable block made by me once for another plane.The wing attaches to the fuselage in the classic way: in the front there is the protrusion for slot of the frame, behind there are two self-tapping screws.The stabilizer attaches on two self-tapping screws, the airplane assembles in 2 minutes in the field.This is the set for transportation:That is all with the description of construction. Check the result on a video.
