The wireless that controls the airplane model control from a distance, the one who mean to make use of the lead-in electric wave  transmission operation does a various flight carriage according to the instruction to the instruction model that the model act.Use the wireless technique to carry on the history that flies the control to the model, can trace back to World War II ago.However, because of civil at that time.Face the very complicated law procedure with the wireless system  sail mold, and the then remote control equipments since bulky and very can\'t, therefore, control from a distance the sail mold and can not expand to open to arrive at this 60\'s in century initial stage, develop along with the electronics technique, various application also starts in the wireless equipments that the sail mold control universal, up to now, the lead-in control from a distance the equipments to have already used for various aviation, voyage and the model on lands broadly.In introductive" fill the 斯纳 "177 a material of the airplane models of this text, what to install is four  passage comparisons to control from a distance the equipments system, it from shoot the parts, such as machine, receiver, rudder machine and power supply...etc. to constitute.

 
  The diagram l show of, is 4  passage comparisons to control from a distance features and each parts of names that the equipments shoots the machine.In shooting the front-panel of the machine, have two control the l,2 passages and 3 and 4  passage action instructionses to manipulate the 秆 respectively, and with manipulate the pole action opposite should of 4 tiny adjust the device.At shoot the machine bottom, the constitution contain 4 rudder machines change toward switch, used for the transformation rudder machine to shake the deflect of arm direction respectively.

 
  Figure 2 show of, is receiver and the rudder machines and the receiver power supplies to equip, among them, the receiver uses to receive since shot the instruction signal that machine spread, through processing, remote control airplane conductor the rudder machine makes and shoots the machine instruction opposite should of action.The battery set provides the work energy for receiver and the rudder machines, it from 4 the common 5  number dry batteries of sections establish but become.

  So-called comparison control, say in brief, is to be we manipulate shoot to pole on boardly from the neutral the position is partial to toward some direction to move the dime degree, with should act opposite should of rudder machine shake the arm to also be partial to move the homologous angle at the same time, the rudder machine shake the arm to deflect the angle and shoot the machine to manipulate the pole to be partial to move the angle comparison.Figure 3 showed to shoot the action relation that the machine performance  rudder machine and airplane model rudders face.When shoot the machine to manipulate the pole( or to should of tiny adjust the pole) to go toward left and right deflect or reply the neutral, carrying out the rudder machine to shake the arm to also correspond the ground to go toward immediately left and right deflect or reply the neutral, the rudder that arouses the model faces to go toward left, right deflect or reply the neutral, manipulate the pole( or tiny adjust the pole), the rudder machine to shake the arm, the model rudder to face to deflect of angle size become the comparison.

 
  4  comparison remote control equipmentses of the passages, can at the same time to the comparison control that the model carries on four dissimilarity actions( for example accelerator, ascend and descend rudder, the direction rudder, vice- wing).Such control already very near to carry the person manipulate of airplane.Therefore, if can make use of to control from a distance the similar to adequately the one who control the principle that the mold form fly, through the assiduous practice of a period of time, manipulate can elephant driver carry person\'s airplane control model of equipments to fly freely in the sky expertly.

  Be limited by the topic and spaces of this academic chair, only synopsis ground of here introduction the comparison control from a distance the principle of the equipments.Shoot the machine constitute such as the figure 4 show, it basically is from manipulate the machine and code the electric circuit, switch electric circuit, high electric circuit of 频 to constitute..Manipulate the machine to link the variable electric potential machine with the variable electric potential  machine electric circuit again the signal occurrence electric circuit- coder conjunction, code the chicken machine occurrence of signal carry to be send out by the antenna to go out on the high 频  lead-in electric wave, this process have a little to be like to carry the goods with the train, manipulating an equal  to freight transportation to adjust one degree member, acting the equal  to goods of the instruction signal, but equal  to train of the high 频  lead-in electric wave," goods" move up" train" of process be called to make.
 
 

  4 passages control from a distance the lead-in electric wave,such as figure, that shoot machine\'s send out 5 show, the Ta_d manipulates the pole to constitute a cycle with the pulse signal and Ts rectangle wave( total 5 signals)s, appearing 30 cycles again automatically about in 1 time. The Ta_d difference with and manipulate the rudder machine side that the pole connects of variable electric potential machine is opposite should, be to manipulate the pole operation, the Ta_d signal changes its time width immediately, urge with the receiver to link to a correspond comparison. The signal of Ts is not to used for manipulating the pole of, short have the longer time width, be the receiver to cause because of miscellaneous interference news the signal alignment mess, it automatic orthopedics of ability.The To that is between the pulse signal is a partition period that has no radio signal, it can do not make the dependable region of receiver have another a signal.

 
The receiver constitute such as the figure 6 show, it basically can be divided in to receive the electric circuit and translate the code electric circuit etc. part.From receive the low frequency that electric circuit come out to output to pass to translate the code electric circuit and can distinguish to take out independently from shoot the machine to send out of manipulate the pole action signal Ta_d.After this process have a little to be like the goods luck to reach the destination station;Unload the goods to combine the classification to give the different user.Receive the electric circuit equal  to connect the goods and unload goods the personnel, they unload after" goods" come, categorize the personnel( translate the code electric circuit) to give the different customer to" goods" from the goods- the each performance rudder machine.

 
The rudder machine constitute such as the figure 7 show.The rudder machine from can take out with shoot the machine to manipulate the pole action the electric circuit of the signal of comparison and can make and that signals opposite the motor and wheel gears that should acts decelerate the organization to constitute.The conduct and actions shoots the action medium between the machine operation pole action and the model action, the credibility of the rudder machine is extremely important.The rudder is mobile to make to shake the in common use shape,such as figure, of arm 8 show.These shake the arm to have the different shape because of the use dissimilarity, dint arm half, radius, strength.In 177  airplane models of" fill the 斯纳 ", the rudder machine shake the dint hip radius of the arm to take 8-10 mms as proper.

 
 
Control from a distance to shoot the machine to manipulate the pole action and models to fly the carriage
  How use to control from a distance the equipments up of manipulate the pole to control the each rudder of the airplane model to face, thus control the flight carriage of the model, everybody\'s habits are all different.For manipulating the remote control airplane model action with carry the person the airplane manipulates the action to further study the larger remote control aircraft( for example control from a distance the helicopter model) of difficulty to prepare to point the method foundation towards should get up, also for the raw recruit.Here, we suggest to adopt the figure 9 the method for show to assign the model each rudder to face to manipulate the pole with accelerator.Shoot the machine front-panel to manipulate the pole up the right side;It lengthways of sport ① use to control to launch the machine to reduce expenses the valve( accelerator), the horizontal sport ② hope( horizontal side) with the vice- wing of control the model.Manipulate the pole for the left side, it lengthways exercise the ③ uses to the rise and fall rudder of control the model( the model lower the head, rise), the horizontal sport ④ uses the direction rudder of control the model.In controling from a distance the next scaleboard of the equipments, establish 4 rudder machines to shake the arm to change toward device, difference to should 4 actions 舷 machine.While adjusting the model to manipulate the action;Need to use these devices to come to certain action direction of the rudder machine.
