Six-Axis Quadcopter Drone Advantages

RC aircraft six-axis gyro stabilization provides much faster correction of attitude displacement than a 3 axis system.  In addition to the three pitch, roll, and yaw gyro sensors, three additional accelerometers are included that sense and automatically compensate for uncommanded movement (acceleration) in the three dimensions. Now our little quadcopter drone can automatically resist flipping and being blown about by sudden wind gusts (try flying a 3 axis quadcopter on a windy day to appreciate this).  

Six axis stabilization also allows sensing of uncommanded sideslip during turns. Very sharp banked turns can now be easily achieved with a six axis quadcopter by simultaneously applying rudder and roll control. Such turns are extremely difficult to achieve with a three axis quadcopters. 

Banked Turn

Accidental crashes with the ground are much less common with a six axis quadcopter. When flying, sometimes we lose orientation and find our quadcopter quickly heading toward the ground. With a six axis quadcopter, all we need to do is let go of the pitch/roll control stick, and apply some throttle.  The accelerometers will sense if the quadcopter is still in motion, and will automatically compensate to rapidly achieve steady hover.  

Finally, the six sensors in combination can detect both unusual attitude (if we're flipped upside down) and can also tell if we're falling to the ground.  By centering the pitch controls, and applying throttle, a 6 axis copter will quickly right itself and come to hover.  This comes in handy if the quadcopter is flying uncomfortably high. Now it can be quickly and safely brought to a more comfortable altitude by simply cutting the throttle and letting it drop. It doesn't matter if the quadcopter tumbles during the drop. Just increase the throttle when it gets close to the ground.  The quadcopter will quickly right itself and achieve hover. This last one is really cool and must be seen to be appreciated.

Six Axis WLToys V212 in Action
It's obvious that for most beginners a 6 axis quadcopter is the best option as it's most forgiving. It's even appreciated by more advanced flyers as a 6 axis quadcopter is also very nimble, able to "turn on a dime". Some excellent 6 axis beginner quads that I recommend that you might consider include the WLToys V202, and V212 quadcopters.  Other's include the Hubsan X4, and the UDI U816. All are available at the best prices that you'll find at Banggood.com. However, please note that Banggood products come directly from China, so there will be a few weeks wait if ordered from them.  But also note that Banggood does stand behind their products, and are more than willing to bend backwards to satisfy you if you have problems.

  2. These articles are excellent and exactly what I needed. Thank you so much! I've had a Hubsan X4 for a few weeks and got to the point where I was stuck on how to progress. I was asking myself how do I turn properly - what is the proper combination of throttle, ruder and roll etc. And I simply hadn't realised all the self-righting etc benefits of the 6-axes. Thanks again, I'm learning so much that was hard to find elsewhere.

  3. Hi, i've been flying Syma XC5 for a while now, and dying to learn manual mode.

    What cheapest option do i have ? Been scouting the web for a while could not find anything suitable.

    1. Am assuming that you mean flying without stabilization input from the gyros or accelerometers. If so, it's a lot more difficult than you think. One way to approximate it is to purchas an inexpensive CG022 or WLToys V252, and attempt to fly it at 100% mode. But even at 100% mode, it's much easier than flying full manual.

  5. Drones, quadcopters, tricopters, hexacopters, octocopters… These unmanned aerial vehicles  bring plenty of fun, and are unbelievably popular nowadays. Experts predict that in the next 5 years they will be even more popular all over the world which is why we think now is the best time to get you interested in how to fly a quadcopter.
