JJRC H20W Pros
- FPV video provides real time viewing of in flight video.
- Video can be viewed on Android or Apple WiFi mobile devices.
- Video includes an on screen alert when the drone approaches low battery power (first that I've ever seen in a toy grade drone).
- Headless mode and one key return. One key return is rather rapid.

JJRC H20W Cons
- Range is somewhat limited at about 30 meters.
- Motors continue to run for approximately seven seconds if transmitter signal is lost.
- Video of my camera appears to be washed out. But this could simply be a single defective camera, and might not be applicable to all H20W's.

JJRC H20 VS MJX X900, Which One Is Better?

JJRC H20 and MJX X901 are the same entry level hexacopter, both in performance and price, if you are thinking about buy one of those two models, in this comparison review you will find out which one is better for you between the MJX X901 Nano Hexacopter and the JJRC H20 Nano Hexacopter. 

JJRC H20 Nano Hexacopter and MJX X900 Nano Hexacopter also comes with nicely packaged, the first thing you notice is the H20 comes with propeller guards preinstalled, more likely to avoid any damage if crashed, for beginners, especially for players with small children, the H20 more safty than X901. Both these Hexacopters look extremely well made: the X901 made in very strong rigid ABS plastic; and the H20 in a thinner plastic favored by the Micro class Quadcopters and Hexacopters. 



Turning both Hexacopters over you will see that the X900 has a battery that is enclosed in the body shell but the battery of the H20 Nano Hexacopter is detachable. This is great feature as you do not get a long flying time with RC models of this size. So buy a spare battery is highly recommend. With the X901 you will have to wait for your battery to charge before extending your drone flying experience. This Round JJRC H20 win. 

About the transmitter; the X900 remote is tiny compared to the remote control of the H20 Hexacopter, it may be OK for someone with small hands, but anyone with big hands is going to struggle with it, it’s so small. The remote control for the H20 is far bigger and far more user friendly. This depends on personal preference.


Both come with led lights, surpport night flight; the X900 Nano Drone with great blue led lights on the back four arms, red on the front two arms perfect for orientation. Three speed modes that are changed by pressing in the left stick and when in top speed or expert mode the Hexacopter will automatically flip if the right stick is quickly pushed in any direction. JJRC H20 Drone no led lights on the arms, the back red led lights and the front blue leds combined, with the two white front facing propellers were perfect for orientation. The H20 Drone also has three speed modes beginner, intermediate and expert and the speed modes are changed by pressing in the top left button on the transmitter. The H20 Hexacopter extremely easy to fly, it was super stable and in low speed rate perfect for beginners. In high or expert rate it was extremely fast. The propeller guards allowed you to ‘Bump’ off walls without crashing. Tested the JJRC H20 outside in a slight breeze and it handled very well and was fabulous fun to fly.

Those two hexacopter are suitable for beginner, if you just fly indoor, the difference is not so obvious, but to fly indoor & outdoor, the JJRC H20 is better than MJX X901, this is only personal opinion. Both models are available on geekbuying, JJRC H20 FRO $18.99 CLICK HERE, MJX X901 FOR $18.89 CLICK HERE

Tips You Need To Know Before You Fly Cheerson CX-10 Nano Quadcopter

If you are thinking of buying Cheerson CX-10 Nano RC Quadcopter, Then see this article for loads of cool and useful tips and troubleshooting techniques.

THE BASICS


There is a front and a back to all quadcopters! The front of the Cheerson CX-10 quadcopter is the direction with the blue LEDs. The back of the quadcopter has red LEDs and the On/Off switch.
The right-hand control stick moves the quadcopter forward, backward, left and right. These directions will always be from the perspective of the quadcopter, no matter which way it is facing or has rotated.
The left-hand control stick on the transmitter controls the throttle (up/down) as well as the yaw, which controls the rotation (spin left or right) of the quadcopter.

CHARGING


Use the provided USB charging cable to charge your quadcopter from a computer. Do not attempt to use an iPhone/iPad, etc wall charger as that may damage the battery.

Never leave your charging quadcopter unattended or plugged in for longer than necessary. All lithium ion batteries can be dangerous if over charge, which may lead to a risk of fire.

The charging is complete when the LED light in the charging cable goes out.

GETTING UP AND RUNNING


Power on the quadcopter on a flat and level surface

Power on the transmitter (always ensure the left-hand stick is all the way at the bottom first)

Now that both the quad and transmitter are powered on, move the left-hand control stick all the way up and then all the way down. You should hear a series of beeps while doing so. When complete, all four lights on the quad should be light solidly and not blinking. If still blinking, please retry.

Your quadcopter is now armed and ready to fly!

FLYING BASICS


There is a front and a back to all quadcopters! The front of the Cheerson CX-10 quadcopter is the direction with the blue LEDs. The back of the quadcopter has red LEDs and the On/Off switch.
The right-hand control stick moves the quadcopter forward, backward, left and right.

The left-hand control stick on the transmitter controls the throttle (up/down) as well as the yaw, which controls the rotation (spin left or right) of the quadcopter.

These movements of the quad will always be from the perspective of the quad, no matter which way it is facing or has rotated. These means that pushing forward on the control stick will always make the quad move in the direction that the blue LEDs are facing.

- When learning to fly, try not to turn spin (yaw) the quad so that the front is always facing the same direction.

As the quad moves around, turn your body so that you are always facing the same direction that the quad is facing. This helps to keep track of which direction is forward, backward, etc

The throttle is very sensitive, try using a very soft touch while learning how to fly. If you lose control, you can always power down the quad by lowering the throttle all the way down, this will shut off the motors immediately. Under normal circumstances, it is usually better to cut the throttle and crash than to have the quadcopter fly away!

DOING FLIPS


To execute a flip, simply push the right-hand stick in (like you are pushing a button). You should hear a beep, which means you are ready to do a flip. Next, simply push the same stick in either of the four directions to make the quadcopter flip in that direction.

Always make sure that you are not too close to an object before conducting a flip. The quadcopter may gain or lose altitude or move sharply left or right while flipping.

CHANGING THE PROPELLERS (Very important)


All quadcopters have two motors that spin clockwise and two that spin counterclockwise. Each of these motors also use a different propeller. If a propeller meant for counterclockwise direction is placed on a clockwise spinning motor, there will be no lift generated.


Each propeller is marked on its underside with either an A1, A2, B1 or B2 marking. The numbers are not important, however the letters are. These letters correspond to the direction in which the propeller is designed to spin.


When changing a propeller, always be sure to replace it with anther propeller with the same letter (again, do not worry about the numbers).- You can also use the picture below as a guide for which motors take which propellers. Please note where the on/off switch is in the picture to ensure that you are changing the correct ones.

RECALIBRATING THE GYROS


There are three ways to correct for calibration issues:

Automatically recalibrate - Power off the quad, place it on a flat and level surface and then power it back on. Wait at least 3 seconds before attempting flight. The quadcopter should now be recalibrated
Manually recalibrate – While the quad is turned on, place it on a flat and level surface. Push the left-hand control stick all the way to the bottom left corner and the right-hand control stick to the upper left corner and hold both sticks in those positions. The lights on the quadcopter should begin blinking quickly. Hold the sticks in that position for at least 4 seconds. The quadcopter should now be recalibrated

The paper trick – With the quad copter off and on a flat and level surface, place a couple pieces of paper under the feet of the quadcopter in the direction that it tends to fly in. This will slightly lift one part of the quadcopter higher than the other side. Now power it on and let it automatically recalibrate. You can play with how many sheets of paper you use until the problem is solved.

USING THE TRIM CONTROLS


There are two sets of directional arrow buttons on the transmitter. Each arrow is a trim control to counteract the quads movement either forward, backward, left or right.

If the quadcopter is drifting to the left, push the directional arrow pointing to the right. This will tell the quadcopter to adjust itself more to the right in order to compensate for the drifting to the left.- It is recommended that you only use one click at a time in to not overcompensate in any one direction.
With correct trimming, you should be able to get the quadcopter to hover fairly steadily.

TROUBLESHOOTING


ProblemOne of the motors seems to be completely dead or is very hard to spin
SolutionsRemove the propeller from the problem motor and put it back on, making sure that it is not pressed down too hard. Props which are pushed in too tight can jam the motor

ProblemThe quadcopter will not lift off or shoots off to one direction without leaving the ground.
SolutionThis typically means that one or more of the props are not installed correctly (they do seem to come from the factory this way sometimes). Please see the above instructions for proper propeller placement.

ProblemOne of the motors seems to stall when tilted slightly.
SolutionThis may not mean there is anything wrong with the quadcopter. It has built-in gyroscopes that change power to the motors in order to maintain stability. If this does appear to be a problem, going through the manual recalibration will fix most issues related to this.

ProblemThe quadcopter flies off in a certain direction all by itself.
Solutions:
1 - This typically means that the quadcopter is not calibrated. Please see the recalibration information above.
2 - You may need to use the trim controls to counteract the drift. Please see the section above regarding trim controls.
Problem: The quadcopter will not take off and only skims along the floor Solution: This typically means that one or more of the propellers is on incorrectly. Please see the Changing the Propellers section above.

FAQ: All About DJI Phantom 4

DJI has just announced the Phantom 4, the latest in the company's line of camera-equipped quadcopters. Of course the newer version flies faster for longer and has a better camera, but the headline feature is the addition of new autonomous flight features that make the drone easier to fly, easier to film, and harder to crash. Look the official promotion video. 


Although not very fond of its look design, but its features is indeed very powerful, so before you purchase it you need know more about this Phantom 4, Below is DJI Phantom 4 FAQ.


Q: 1. What is ActiveTrack?


A: ActiveTrack allows an aircraft to track a moving subject without a separate GPS tracker. Simply tap on the mobile device screen inside the DJI GO app to select the subject to be tracked. The aircraft will lock on the subject and start tracking it automatically from a safe distance.

Q: 2. What is TapFly?

A: TapFly means you can fly in any direction with a tap of the finger, without a remote controller. With Obstacle Avoidance turned on, the aircraft will automatically avoid obstacles, slow down or hover when required, provided that the scene is bright enough ( < 300 lux) or too bright ( > 10,000 lux).

Q: 3. What is the Phantom 4 Obstacle Sensing System?

A: The Phantom 4 is equipped with an Obstacle Sensing System that constantly scans for obstacles in front of it, allowing it to avoid collisions by going around, over or hovering.

Q: 4. Why does the Phantom 4 have a magnesium core?

A: The revolutionary magnesium core embedded into the aircraft greatly increases rigidity, minimizing unwanted vibrations. This ensures the precision and performance of the inertial measurement unit (IMU).The weight of the aircraft is also reduced through this magnesium core.

Q: 5. What changes were made to the Phantom 4 remote?

A: The Phantom 4 introduces a Sport mode, accessible through a new trio of modes, P, S and A.P (Position) mode is the standard mode, giving access to normal flight as well as Intelligent Flight Modes, ActiveTrack and TapFly.S (Sport) Mode unlocks maximum flight speeds of up to 44mph (72kmh)A (Attitude) Mode remains the same and removes satellite stabilization in flight. It allows the Phantom to move more smoothly and naturally.The ‘Playback’ button on the top right of the remote controller has been changed into a ‘Pause’ button that lets you put the Phantom into hover during any Intelligent Flight Mode, ActiveTrack or TapFly with a tap.

Q: 6. What improvements have been made to the Phantom 4 Vision Positioning Unit?

A: The Vision Positioning System now uses four sensors to increase hovering accuracy and reliability, creating a more controlled flying experience. Its sonar system has been improved and now functions from up to 10 meters off the ground. In ideal situations, these combine to give the Phantom 4 Vision Positioning System a vertical hover accuracy of +/- 0.1 m and a horizontal hover accuracy of +/- 0.3 m.

Q: 7. What is the effective range of the Obstacle Sensing System on Phantom 4?

A: The effective range of the Obstacle Sensing System is 0.7 to 15 meters. Although the DJI GO app will indicate when there are obstacles present, pilots should always be paying attention to the aircraft during flight.

Q: 8. Does Obstacle Sensing System work in all modes?

A: The Obstacle Sensing System can be enabled in ActiveTrack, TapFly, Normal mode and all Intelligent Navigation functions.

Q: 9. What are the major improvements in the Phantom 4 propulsion system?

A: The motor on the Phantom 4 is designed to work with the latest Push-and-Release Propellers. With this locking mechanism, propellers can withstand drastic changes of motor speed, allowing the aircraft to be more agile and more responsive to the pilot command.

Q: 10. How long does the Phantom 4 using the new Intelligent Battery?

A: At sea level in calm environments when flying in Atti mode, the Phantom 4 can achieve 28 minute flight times. This will vary due to different flight patterns, weather conditions and altitudes.

Q: 11. What are the major differences between the Phantom 4 propellers and the Phantom 3 ones?

A: The new Push-and-Release propellers are faster to install and more secure than the Self Tightening propellers used previously. This security allows them to handle faster acceleration and harder braking.

Q: 12. What makes the Phantom 4 gimbal better?

A: The gimbal and camera system is integrated into the body, bringing it closer to the aircraft’s center of gravity. It is also made of a rigid and strong composite material

Q: 13. What makes the Phantom 4 camera better?

A: The Phantom 4 camera has been improved in terms of image quality. Chromatic aberration has been reduced by 56% and lens distortion had been reduced by 36% compared to Phantom 3 Professional. In addition to lens improvements, camera firmware has been tweaked to enable the camera to capture 120fps video in full 1080p FHD (the camera’s field of view will be reconfigured to 47° when recording in this mode) for smooth slow motion. The camera is also used for ActiveTrack and TapFly modes.

Q: 14. Why add a redundant IMU and compass to the Phantom 4?
