  If you are having problems with  v3.2.1 on APM 2.x hardware and your multirotor is unstable and won't sit still but worked fine with v3.1.5 or v3.2, try changing the parameter INS_MPU6K_FILTER to 20 or 42 rather than the default of 0. The value of 20 is preferred for an APM 2.x flight controller.

  As I understand it, the value of 0 used to default to 20 in earlier firmware but is now an absolute value. Changing this param cured the problem I had with 3.2.1 on a Cheerson CX-20 and it now flies smoothly with the final firmware released for APM 2.x. I'm really liking the PosHold mode!

  @Darius Jack,

  I do find it annoying too since you might not have the last setup you used available on your current test. They might do it if they hear from too many people for them to turn that option off.

  Can we ask developer of eCalc to disable

  random fooling option ?

  it will keep changing the options you see at random every time you open eCalc.

  @estebanflyer, You need to get the paid account to get access to all options. If not, it will keep changing the options you see at random every time you open eCalc.

  Does anybody know why Ecalc is showing different motor types on different ocassions? I opened four tabs and in each case the RCTimer motor selections showed different numbers:

  @Ken Costigan are those ESC to motor bullet connectors bare like it looks in the photo, or are they covered some something like clear heatshrink that you just can't see? If there is bare metal then that's what's causing the crashes!!

  During operation of the motor there would be enough vibration during flight that the bare metal would momentarily touch, especially during changes in direction at speed. Every time they touch that motor would stop briefly, and if that happened to two or more motors at a time OR any single motor were stopped long enough, down she comes!! Pretty much you are guaranteed a crash flying like that...

  Get some heatshrink on all of the bullet connectors going from the ESC to the motors and see if that makes it fly better. It may not be the only problem you have, but it certainly is a show stopper and needs to be fixed before your next flight.

  Arducopter stuff might be the coolest stuff EVER!

  I would like your help.  Safety is my number one issue with drones. Last year I was learning to fly my  Parrot AR. Drone that I had fitted with carbon fiber blades.  I was doing a simple take off and landing in the living room to impress a friend.  I was hovering and accidentally hit the "Home" button. Instead of a soft landing the AR Drone took off from a distance of about 10' from me and came right at my face.  As I was trying to deflect it, the carbon fiber blade put a gash on my left eye, just missing my eyeball.  I don't know about you, but that really soured my experience and nearly put out my eye. 

  I had every intention of taking the money I had saved to start a Real Estate Photography company.  Instead I became afraid of the drone. A friend purchased a Phantom from DJI and had a very similar experience on his very first flight.

  Oddly enough I became so fascinated with the industry that started to look for solutions to the danger of any multi-rotor with plastic or carbon fiber blades.  I came up with what I affectionately call DroneKone.  It is complete and substantial propeller protection to help make drones safer.

  I started a small company with my limited funds and developed a model of my concept.  I was able to get a provisional patent on my safety device.  Then I had a devastating life event and was out of action for a year.  I have recovered.  I don't have any funding at this point except out of my pocket and started seeking funding. I was told by a potential investor that I needed to survey 100 people to find out if my product is market worthy.

  Okay enough story.  Simple Survey for Safety:

  1. Yes or No  Are you concerned about drones flying around Children? 
  2. Yes or No  Do you have a concern about your personal safety when flying a drone?
  3. Yes or No  If a safety device was available would you consider purchasing it?
  4.                  What would a safety device look like to you if you could design one?
  5.                  How much would you pay for a safety cage if one was available when you purchase your drone.

  I greatly appreciate you reading this far and ask for help.  If this is just plain stupid, then I would like to know that now, before I spend any money on moving further.

  Thank you so much for listening.  I am grateful to be a small part of this awesome community.
