HobbyAnt - MJX X904 RTF RC Quadcopter Lntroduction And Evaluation

MJX X904 with reverse power design, because of the unique shape of the structure, the use of inverted design of the motor and fan, the use of reverse power, the same can easily control, built-in six-axis gyroscope, built-in six-axis gyroscope flight system to ensure that the aircraft The stability of the stability and stability of the flight and hover, so that the aircraft in flight can be more stable shooting.

MJX X904 Transmitter high and low speed switch, remote control using second gear speed mode, according to their own control situation to switch to vulgar and high speed, the degree of increase in turn, beginners and professionals are optional .2.4GHz wireless technology, fast response, Ability, 2.4GHz is the use of specific frequency band, if you want to convert into the familiar MHz, then it is 2400MHz, so also known as high frequency, in general, is not caused by the same frequency interference, and 2.4GHz band put dry But also the first to achieve results .2.4GHz has a great advantage, even in the same space there are other people in the flight does not need to determine the frequency, that is not the same frequency interference problems, do not need to crystal exchange Cumbersome frequency change action.

MJX X904 with a key 3D roll, the aircraft flew to more than 3 meters after the height, press the normal mode / tumbling mode key to switch the roll mode, the throttle speed up, followed by the remote joystick forward / backward or left / Right side of the fly in any direction to play in the end, and then quickly back to this time, the aircraft can achieve the corresponding direction of the rocker rolling action.Every time to complete the rolling action need to push the original height and then push the throttle , And pause for 2 seconds before completing the second rollover action.

   

HobbyAnt-Product evaluation:WLtoys V922 RC Helicopter

Wltoys v922 rc helicopter appearance, head cover red-based. The overall body design with the 911 is almost the same; tail rod, tail rotor with the tail hood are exactly the same with the 911. Base material is softer, the tail motor with 911 the main motor a bit like the main motor should be a brush, turn the wing, the resistance is great, the interval is great.

Wltoys v922 rc helicopter steering gear is really semi-open semi-bare for a straight steering gear. Its role I guess is to save space and save costs, in fact, all aspects of the aircraft components are made of low-quality plastic, hood and base are very very soft (head hood end of the bayonet deformation), tail It is only a piece of flexible plastic sheet that can be bent. The main material should be plastic.

Wltoys v922 remote control is large, if I want to use the index finger plus thumb to hold the two joystick inward (switch direction) to the end, will be more difficult.
It is worth mentioning that this control has a let me shine function, that is, anytime, anywhere easy to switch four ways. In the top of the key to open a relatively heavy slider, engraved L with R, pull about you can switch left and right throttle stick. There are two kinds of throttle sticks in my chart (see the throttle stick position). And then turn on the control, press the button will be able to switch the hands of the United States hand with Japan; the back of a simulator interface. I never play the simulator, so do not introduce the battery cover is directly open, 4 * 5 electricity; charger with the battery connection, which must be inserted two wires Caixing. Charger is just above the two openings like 911 charger (in fact, the opening is not the same), but in 922 seemingly completely useless; spare parts to the main tail rotor, Phillips screwdriver, mini hexagon with some connecting rod Ah helm arm ah what ah. Quality is more times; the battery is full or not connected to the battery green light; before the flight is the first open control, then the power, and then the green light flash, the body has been issued a light and harsh voice, intermittent in the telegraph. When the power of the main paddle and steering machine will be fretting, but will not issue a self-test the end of the sound, get me do not know how long to wait. It is estimated that wait until the green light continued it.

Wltoys v922 rc helicopter-The body of the helicopter is very light and very light in relation to the torque of the main paddle. So take the time to throttle a little push, the fuselage will be in place immediately spin, and finally lose stability directly lead to the main paddle hit, take off failed. So take the time to use the most slow speed to push the throttle, until the tail motor to force the putter take off; In fact, Wltoys v922 rc helicopter gyroscope is very focused on the power when the position, so whenever the fuselage in the non-smooth The state of the power, will lead to gyroscope offset, take off when the main paddle hit, take off the failure; normal mode flight should be no problem; pitch curve, throttle curve, gyroscope all adjustable. Remote control function is more than the toy control more than two twist switch, and then you can wantonly switch four ways. The appearance of slightly the atmosphere; the main motor output is very strange. Stable hover after pushing the throttle, slow speed. The sound of the throttle sound. It is estimated that the normal mode of the main push by pushing the pitch; the main motor is a brush motor, caliber than 911 large.

Wltoys v922 with Wltoys 911 common advantages, that is, fried. Today in the living room test flight, due to the relatively slow feel up one did not adapt, the main paddle hit the ground ah ah ah on the sofa on the treadmill, the results are nothing. The maximum is to pull off the control re-calibration gyroscope with the steering gear, throttle slowly push and take off. This should be attributed to the low power of the main motor.

HobbyAnt - Hubsan X4 H107C RC Quadcopter RTF

Hubsan x4 h107c quadcopter without real-time video transmission function,and its video module is also different with the H107D,the aircraft module has a Micro-SD card slot,used to store aerial recording video use.hubsan x4 h107c drone also designed with a wrestling soft corner pad.

Before the flight,the player needs to manually press the switch,if the inside of the light from the blue light to red flashing,that has begun to video.After the flight,press this button to save the video before you can power off and remove the Micro-SD card.

Hubsan x4 h107c plus can support more than 100 meters of control distance,or because the visual can not see the aircraft,causing the aircraft to fall off high altitude.But the good Habson H107C aircraft strong enough,although the damage of a number of blades,and the protection ring also crashed,but the body of the hard damage is still not very large,but also normal flight.

HobbyAnt - XK K120 RTF Brushless RC Helicopter

The first time to fly XK K120, it is recommended to follow the instructions set, pitch 70 is enough. Before there are X6 control K110 do not forget to give K120 another build a module, if the 3D mode or 110 80 pitch, all of a sudden can not meet the danger.

XK k120 helicopter motherboard finally flattened, and there is no before those glass glue, looked very refreshing. The new machine must check the motherboard fixing screw, do not be too loose, because the factory sponge glue above the layer of oil and paper did not peel off, the motherboard is not sticky sponge pad, just pressed on the above, the rest of their own want it. Try the next spin, run badly, should not tune well. K120 tune well, the direction of the right to death, no wind in the case can have been in place, spin optimization is very good.

The only change in the new version of the servo xk k120 rc helicopter is: more glue fixed. Very fast, can only be used to cut the gap with the knife can only be released, we do not have to tie the line ah, paste the tape and other self consolidation. I 3D fly two days 12 electric, every time the tail is not hot, really not hot! Lock tail feeling with 110 for large tail pulp after almost, are good. Just turned to the fine as K110 smooth, a little hard, power is not to say, the first is the wind resistance, 120 much better, slightly larger winds will not like 110 up and down as the channeling. Accuracy and stability than 110 good, easy to do action. Chassis and other large legs tripod are thick, but the upgrade 2S this should be. 120 new machine and the same new machine 110 in the hand to experience the highest speed under the shock, but K120 vibration smaller, no, basically no vibration, which is the difference in accuracy! Well first, I remember the bad, the other thought to add it. Yes, the appearance of 120 is also an advantage, above a set of metal and carbon fiber lines tail pipe.

HobbyAnt - GTeng T901C Tiny RC Quadcopter Evaluation

gteng t901c try to choose a relatively open over, there is no shelter of the flat (except indoor small aircraft) if the lawn is more ideal. The plane can not be used to completely no electricity and then re-charge or put to play when the re-charge, as long as the aircraft can not fly to charge. Do not use the aircraft's waste is also used to clean and then recharge, the aircraft battery will cause serious damage, there will be no charge and so on, we must pay attention! Remember!

GTeng T901C Tiny RC Quadcopter the most likely to make mistakes: fly too hurry, the joystick pushed to the top, the helicopter became a space shuttle, straight into the sky; avoid landing or reduce the height of the second will often appear wrong action: take it for granted to give up manipulation, (The electric helicopter and the electric glider, the glider has a fixed glide can slowly glide down), the helicopter once the wireless signal is not received, the propeller is to stop working, this time the helicopter fell to the ground, although the helicopter are seismic design, but Not conducive to extend the model life.

GTENG T901C the correct way to fly: Although the remote control aircraft easy to operate, good stability, but after all, is an aircraft, to control it is also a question, only to continuously improve their control skills, Fun, so it is strongly recommended that you must carefully read the instructions before the test, do not rush to the real machine operation. If you want to control the play by the child, you must be in advance to fully grasp the relevant operational essentials, and give the child a timely help to guide; early fly to fly low (1 m or so), push the joystick to half , Feel the manipulation of the handle, to make the helicopter fly high is not difficult, but to fly to be able to hover in the low hover, before and after the free turn and precise fixed landing, that is great master, control electric helicopter's greatest pleasure In this case, but to achieve this level usually need 5-6 voyage (charge a power for a voyage), not impatient.

HobbyAnt - A review of Hubsan X4 H107L RC Quadcopter

THE Hubsan X4 H107l is actually a remote control aircraft, its size is very small; weight is very light, even if the weight of the handle is only about 250g, while the aircraft itself is only palm-sized. After a period of experience we found THE HUBSAN X4 four-axis aircraft as entertainment is too much to use, mainly because of its compact body to provide portability.

Hubsan H107l four-axis aircraft using a wireless 2.4GHz connection, the farthest connection range of 150 meters (the actual use of this distance are very difficult to see the aircraft). In addition, THE HUBSAN X4 four-axis aircraft standard accessories, including aircraft x1, remote control x1, aircraft battery x1, battery charger x1, accessories is quite comprehensive, but the remote control also need to purchase another 4 7 batteries.

THE HUBSAN X4 four-axis aircraft remote control feel slightly larger, but the overall sense of grasp is very good, more comfortable to control. THE HUBSAN X4 remote control handle in addition to the conventional two control rod, but also the design of the direction, lift, throttle, aileron fine-tuning, the player can play in accordance with the aircraft body tilt, targeted to fine-tune the aircraft, To achieve the best balance effect.

This is the Hubsan X4 Quadcopter Drone four-axis aircraft it! Only the size of the palm of it it is the weight of the battery only less than 40g. From the appearance of view of the HUBSAN X4 four-axis aircraft a bit like "frog", the overall structure of the fuselage is mainly four motors and a central control of the core and the battery composition, the use of lightweight; high toughness of the material design of the fuselage The
Although it appears that THE HUBSAN X4 aircraft will feel very fragile, but the actual use we found that its anti-drop is very high, often a few meters high altitude suddenly fell off nothing. However, its propeller may not be so force, and in the absence of a protective device, the propeller of the THE HUBSAN X4 is easily damaged in the crash.
