Skin and assembly models
Five parts produced, after carefully polished smooth with fine sandpaper, you can skin of the wing and vertical tail. I used thin copy paper, glue it to Mongolia after the surface of the part, you can increase the strength of the foam surface, but also free to paint with paint on it.
The whole machine can be assembled wings and tail skin after. Note that the forward fuselage assembly mounted in the rear fuselage of the first motor frame fixed. Motor frame with thin plywood production, assembly of the fuselage to the rear of the fuselage glue pressed "solid core" inside. Motors do not add installation angle in any direction, if you must change to achieve thrust line, you can use different thicknesses of rubber gasket on the motor bracket to change the angle of deflection.
Adhesive foam, I tend to use white latex, although the drying time is very long, but use it to foam bonding interface strength and the strength of the surrounding material not only has a good consistency, but also has a certain flexibility. When damaged model, interface is not easily broken. Note: When the adhesive area is large, without adequate drying time, do not think outside the glue dries on the line. When I made this model aircraft, with real dried for about 24 hours.

Plane model aircraft of paper skin is easy to coating for model fans, Friends of the majority of the mold can enjoy the level of play to their paintings to decorate the love machine. By real aircraft painting, the surface should be gray, light gray lower surfaces, to a certain extent, is a protective color - deep back, abdomen shallow, the opponent in the air is not easy to distinguish. And when we manipulate the model you need to clear to see it flying in the air is very bad. To this end, I used the end of white, badge, ID, etc. are modeled on the color of the real machine, and then draw a thin line cockpit, skin lines, rivets, good results.
The characteristics of the model test
The model of no horizontal tail is more accuratek, because the pitch is not easy to adjust the balance. Therefore, the test must be checked before the formation throughout the body structure and symmetry; to ensure that the center of gravity position ( before and after adjustment methods available mobile battery ) 1 /4 of the front center of the chord; sides of the aileron should also upturned 3 ~ 4mm. After adjusting the position of the center of gravity, the need to throw the first pitch hand balancing test method for testing the model.
According to experience, found a slightly higher than the surrounding ground, open the remote control, the model is powered from a high level to be cast out, and to observe its flight, because of the high standing position, when the model appear the serious situation of " head light "and" heavy head ", you can use the remote control to the availability of its smooth landing, and will not break. If the test found throwing hand model "first light " and " top-heavy ", but in line drawings mark the position of the center of gravity, do not adjust the center position, but should modify the aileron height, or use the remote control to fine-tune the pitch channel to compensate. If you need to adjust the amount of large, fine-tuning the remote control has been insufficient to compensate, you should directly extend or shorten the length of the cabin Rack .
Hand throwing a preliminary test of the model after adjusting，carryong a experiment of a power level flight: to open a small force, thowing the model level by hand, obser model can maintain some level flight or decreased. After level flight tests, to know what the two ailerons should be adjusted to the position, then the method can be used to adjust the length of the cabin Rack. This small power level flight can be adjusted to the remote location of the center position. This test even the most difficult hurdle passed, later large powered flight would not repeat when adjusted.

This frame impetus foam model aircraft, flight weighs less than 300 grams, more suitable for young people making and flying. Relatively high aircraft propeller at the front of the model aircraft safety performance, even during the flight or landing hit people or things, there will not be much damage. I made model airplanes have a better grasp of the fuselage, very smooth take-off and landing; two large vertical tail to make the flight attitude particularly stable. Then according to the proportion of different sizes made several aircraft model aircraft, small wingspan of less than 400mm, not much bigger than the remote control, because of the relatively large cell stack weight, wing loading close 30g/dm2, is slightly larger produced using fiberglass fuselage, and the electric power system uses a ducted propeller, as the real higher.
Finally, to remind everyone that will produce chlorine and other harmful substances and processing with electric wire foam pile, though rarely, it should be taken to avoid inhalation, in order not to affect health. I used the kitchen exhaust hoods and fans methods harmful gases blown away.
If you are interested, you can also try to try. Good luck.
