Today,I want to introduce a model airplane to you.This model airplane is made by myself, the method is very sample, you can try.
This frame quick released model aircraft designed inspiration from disassembly and convenient mountain bike. Whole machine weighs only 12.4g,can be split into seven parts: wings, tail, fuselage, wings connecting frame (including front landing gear), power systems, receiver and battery. Position can be adjusted around the wing, the mounting angle can be adjusted within a certain range.

Second, the production process
1,power systems
1),the production of motor frame
Motor frame can be divided into the front bracket and rear bracket. First, determine the motor right corner and pull the pull-down angle, then calculate the distance of the latter bracket mounting holes around the midpoint; then use the software to draw the desired pattern, painted with a laser machine CCL surface (directly engraved with engraving machines down better); finally come out with a milling process. The best shape accuracy bracket higher than 0.2mm, or will cause great shock when the propeller rotates at high speed.
2), the assembly
Prepare a diameter of 1mm, about 2mm long steel shaft, a 1mm diameter shrink tube, two collars and two spacers (removed from the motor shaft diameter 1mm), assembled, and then transferred hot air gun to 120C. Blowing heat shrink tubing to make it shrink; checking whether the rotating flexible shaft, if you need to adjust and flexible plastic fixed point 502, and finally put on the propeller.
2, making the tail
1), wood production and skin structure
Tail uesed light wood and tissue paper as the timber. Note that when attached to tissue paper, you use the camera gently flatten and then sub-Mongolian reply.

Tail light wood and timber as tissue paper. Note that when you have to use the camera attached to tissue paper and gently flatten further sub-Mongolian reply.
2), with a knife from a plastic sheet 0.2mm thick (also later) under a wide cut 1mm, about 20mm long plastic strip, and then use the heat gun (about 100 ℃) while blowing side pull, until the plastic strip is not then extended from the middle hinge as it cut 10mm. Repeating the above steps were produced 4. Then with a knife between the flat surface and the vertical tail rudder mounted fixed position slotted hinge (not to install the rudder).
3), the installation of electromagnetic rudder
Electromagnetic coil leads rudder is very short, but some welding extension cord is very troublesome, it can be pulled down for a period of lead wire (wire diameter is small, must be careful when pulling) from the coil; then glue it with 502 coils mounted on the tail (Note that the two coils do not rely too close, otherwise it will be affected rudder magnet). Another with a diameter of about 0.4mm of the magnet wire wrapped tied , point 502 glue , and then glue the magnet 502 fixed rudder surface.
4), mounting the rudder
Hinged even after a good paper plane and rudder fixed to both tape and paste it, then peel off the pre-flight, in order to avoid accidentally damaging the tail.
3, the production tail connecting frame
First, draw the desired shape using the software, and then get the monolithic laser cutting plywood connecting frame. Then connect both ends 0.8mm carbon rod penetration groove frame pieces and cement; finally placed on the end of the connecting frame piece fuselage 1.4mm carbon rod with heat shrink tube stop.
4, making landing gear
Interception of a length of about 17mm, 1mm in diameter wire, bent at approximately 10mm at its 45 °; then this steel and 10mm 65mm, 1mm in diameter at one end of the carbon rod 10mm piled up, tied together with a 0.4mm wire; Finally, point 502 plastic and wrapped in shrink tubing. At the other end is mounted on a steel wheel and wheel block.
