Due to the higher the height, the lower the air density, so the model plane flight level are generally much lower than that of fixed wing helicopter, even so have distance is much larger than our visual control and remote control distance, so it can be for the aircraft’s flight altitude and flight distance is the distance from the security of the remote control equipment remote control and visual range.Form special smaller model planeusually flying height can reach more than 20 meters (about 5 to 6 floor
How much empty flight time (time) is mainly determined by the power system.Such as the motor power of the electric model planeusing size and carry the battery voltage and capacity, move the model planeto use engine oil displacement and carry fuel volume. General electric or oil on a single charge or the blank after refueling time in 10 to 20 minutes or so.One is energy weight limit, the other is also considered to avoid the pilot lot of concentration for a long time transition fatigue caused by the manipulation of the error.
Since the stability of the model planecan’t be compared with the fixed wing aircraft.Besides the structure of the coaxial sculls again helicopter, there is no a model planecan not control condition for a long time and stable floating in the sky (usually within 10 to 20 seconds off balance and fell to the ground), so you have to keep a spirit highly centralized control!
Due to the beginners in the first place has not been formed in the brain to control the direction of a reflex, so often under the plane in a flight attitude, through a transmitter to the plane error motion commands, and even the brain a blank, and the plane can’t give enough time to correct the pilot, and fell to the ground.As long as the correct constantly practice can be easily manipulated. In the early also can be finished with the help of a computer simulator practice.
Why a model planetake-off will shift to the left or elsewhere, rather than a straight take off? Due to the influence of the gyroscopic effect and the main oar downwash flow, so the general model plane leaning on takeoff is normal! Need to slightly to the right to play some aileron control lever level control lever (right hand), rather than through the aileron trimming correction, stability, hovering around the body of the lateral situation then adjust the aileron fine-tuning. If in the other direction deviation can be on the ground when the modification of fine-tuning.
Hovering model planeis peculiar to a way of flight is also the charm of model planeflight! Just as its name implies is almost still stay in the air of a model planein height, which can accomplish common fixed wing aircraft was unable to complete the task! For beginner friends must begin from hovering flight of practice, because of the model planetakeoff, landing, and other action is the beginning and end of the flight need to first enter the hovering flight status. So the hover became the base of model planeflight practice subject!
What is the average cross control mode? What is a CCPM cross plate control mode? What is the difference between them?
In normal mode cross set control mode, the operation is completed only by the aileron servo aileron, elevator operation is completed only by lifting the steering gear, the change of pitch is only done by pitch steering gear, three steering gear.Such as changes in pitch three steering gear up and down movement of push-pull cross at the same time, the aileron motion at the same time by the aileron and pitch steering gear 1 push pull to finish at the same time, the lifting action by lifting the steering gear and flaps and pitch complete 1 on 1 of the steering gear. From the point of view of the above difference, compare the difference between the two normal mode for single steering torque requirement is higher, because only one single action steering gear, and CCPM any single action at least two steering gear, so low torque requirements for steering gear. CCPM on steering performance, however, the consistency of the demand is higher, steering gear stroke and speed should be as far as possible, otherwise it will cause deformation, such as changes in pitch when the above three steering gear with, if the schedule is different, can cause the cross plate under different pitch, a tilt. If the speed is not the same, also can cause pitch change cross in the dish.For flight performance for beginners don’t feel what’s the difference between the two, requirement for electric model plane device light weight CCPM has more advantage on the weight and the power of movement, so if the 3 d flight CCPM will reflect obvious advantages! The ordinary flight CCPM also more stable performance.
What is the pitch? Pitch refers to the model plane rotor or fixed wing of the propeller rotates 360 degrees, up or walk forward distance (in theory). Is just like a screw, screw you after a circle, can the length of screw in. The greater the pitch forward distance, whereas the smaller! However it is difficult to measure the actual size of the pitch, so general fixed wing aircraft using the same pitch labeled on the propeller of the diameter and the size of the pitch (mostly in the unit in inches), and in order to facilitate the appropriate engine systems. The vast majority of fixed pitch of model planeblade is generally designed for a certain level of customization, so only indicate the diameter. Variable pitch model plane can be very easily by measuring the Angle of attack of the blade Angle (wind) size to reflect the size of the pitch, and change.
Any remote control model plane is inseparable from the steering gear.It is the most important application most ultimately perform the pilot instructions.It is generally a small (black) box, box mounting holes are on either side of a output shaft, can install a circular or a glyph (cross) arm, and a the same 3 core signal cables and electronic governor, the corre sponding channel interface connected to the receiver.When transmitter remote control lever is pushed, the steering gear of a certain rotary Angle of rotation arm muscle together, Angle depends on the range of the remote control lever is pushed. Convert electrical signal into mechanical force, driving the rudder surface of the plane.
