I started from the fuselage construction. While constructing I used glue PUR 501. I prefer this glue as it fills in all the voids and makes the model solid.I used two glued 3mm pieces of plywood for motor mount. To mount servos I glued a bamboo stick from an ordinary sushi mat into the foam.To cover curved parts with tiles without breaking them I pierced the lines on the inside with a blunt tool and then covered the outside with the masking tape.The ceiling tiles therefore bent without breaking. I used masking tape to keep parts in place. It keeps them safe and it is easy to remove after the glue solidifies.To mount the wing on the fuselage I used 6х8mm pine railings and fixed them with a 6х6mm railing.Inside I used bowdens made of joined earbuds. I used 0.8mm wire from plastic corrugated cable tube.The fuselage bottom was made of double tiles. For gear mount I left an opening in the outside layer and glued pieces of plywood into it.I weighed the construction up before covering it with tracing paper, its weight being 128g. Then I started glueing the tracing paper with aqua lacquer. The process is very simple. I was soaking pieces of tracing paper with aqua lacquer and putting them on tiles. Afterwards I covered them with double layer of aqua lacquer and dried them up at room temperature. The tiles never deformed, the aqua lacquer dried up very fast. Then I weighed the construction up again, it weighed 146g.I painted the fuselage with acrylic spray paint and weighed it up once more.The added weight for the fuselage without the tail section comprised only 24g. This way the plane looks better than when covered with tape. While painting I covered other parts with masking tape.Then I prepared the tail section and glued it into the fuselage, minding the geometry with the help of a ruler and electronic level.To mount the wings I used squares of double plywood. To fix them I used 6mm furniture threads and M6 nylon srews.I soldered gear legs of steel 2mm umbrella needles, but then altered this construction as the legs bent at landing. I made the new one of a 2mm long 15cm wide aluminum stripe and added 0,8 mm steel wire braces to prevent it from bending. The video features the new construction.The battery used was 3S 2200 mAh. To mount it I made a special plywood trap.Servo used is HXT900. HXT900 Micro Servo 1.6kg / 0.12sec / 9g

Product http://www.rcfair.com/en/product/662/ To mount the receiver, regulator and battery I used self-adhesive velcro strap and additionally PUR 501 glue.The tail wheel was ready-made and connected to the rudder with a bamboo stick. In a test flight it never fell apart, the steeering was good.The pilot is definitely too small for a plane of such scale, but there wasn't any bigger on sale, besides it flew very well.The wing was crafted on self-made stocks angled V 3 0.Airfoil chosen was Clark Y 12% . The wing spread comprised 1100mm, wing chord – 255mm. Wing area – 27.3 dm2, wing load – 40.2 g/ dm2. Ribs were made of 8mm wide XPS (extruded polystyrene) . For wing spars I used 3 6х6mm pine railings.I strengthened the wing center section with XPS pieces. I drew the servo extension wires and mounted HTX900 servo . I put bamboo sticks on ailerons for rigidity.The wing was covered with tracing paper on an aqua lacquer base and painted with spray paint.

I mounted the motor on a ready-made motor mount and made a cowl out of a plastic bottle.I used a barbecue stick as a wing strut. I also added electric end pieces and secured them with 3mm self-tapping screw, which are threaded into 6mm studs glued into the fuselage and wing.The finished model without a battery, total weight 943g.It might be lighter, but the flight is steady, very much like a real plane. The flight was steady even on the 4 m/s strong wind.Due to work issues I wasn't able to test it right away. The first flight took place in March 2016. I had to put skies on gear legs. I made skies out of cans, the technology is described on Youtube. I'd say that it isn't suitable for models weighing 1 kilo and more, because tin wouldn't endure and falls apart at the brazing joints.I didn't put ski on the tail, as the snow is quite firm, the wheel steers good.Gravity center was 30% MAC. To achieve it I added 30g ballast to the nose.



Both the construction process and the flying were highly enjoyable. I used the 10х5 APC propeller. APC Style Propeller 10x5 Bone

Product http://www.rcfair.com/en/product/1198243/ It copes with the power very well. Motor slant was set downwards and to the right to 2 0 , without it the plane went sharply upwards and steered right pretty bad. Servo travel is 20%, pulls up quickly, on takoff tends to bounce upwards.The plane is easy to steer, the speed is average. It can easily make loop and barrel-roll maneuvres. No stalls were noticed at low speed. At landing I use flaperons, they slow the model significantly down in windless conditions. I'd like to emphasize that the flight looks very realistic, especially at close range.
