"Looks like quite a few have signed the petition since I last looked, although to give it legitimacy I think its best signed by only those who it potentially impacts.
Lets hope the UK Parliament tells them where to go. Surely this is a matter for the…"

Stuart Brookes replied to Simon's discussion Copter rotates around own z-axis
"yes that needs sorting either way, especially if they are all like it and lean the same way. if it isnt the problem, it will still fly better after the problem is found. 

maybe some washers between the motor and arm. hope it fixes it, let us know…"

"I'd be amazed if the cable has enough effect to do that.

I haven seen his with an incorrect motor direction before I don't think...but are you sure all motors/props are the correct direction. I am guessing posiiton is correct. motor order is…"

"I am very rusty at looking at logs, this is prob the forst I have looked at in about year.

but looking at RCout your CCW motors are being driven much harder (pretty much full beans) compared to CW.

des yaw is designed to chase if the copter cant…"

Stuart Brookes replied to Ivan R's discussion hexa flyaway - slow descent with constant yaw...no control response...mad :(
"You aren't running full logging. RCout would have been handy, were all the motors spinning? Thr out rose to max when the yaw started."

Stuart Brookes replied to Nils Heidorn's discussion ArduCopter 3.21 on APM 2.6 Hexa: strange yaw "pumping" and unbalanced motor output
"yeah it should be at the centre, but your front motors outputs are higher than the rear. Being its a small multi it may be particularly sensitive. Thats assuming its not some wierd esc cals.

Unless you have a bewer version of the firmware I have…"

Stuart Brookes replied to Nils Heidorn's discussion ArduCopter 3.21 on APM 2.6 Hexa: strange yaw "pumping" and unbalanced motor output
"To me looking at RCout in your log it looks nose heavy.

Yaw just looks like it needs tuning to me."

Stuart Brookes replied to Michal Rus's discussion Quadcopter with down facing motors/props
"On of my next builds will probably be upside downers.

I did see a thread where it showed a measurable if small benefit (can't find it now but it was on DIYD). The prop wash under a prop isn't the same as above. Ever noticed you can't rally feel the…"

Stuart Brookes commented on Patrick Duffy's blog post How to control a GoPro Camera on APM/Pixhawk with a Raspberry PI using WiFi
"I have seen reports of people losing radio due to the WiFi. Its not exactly the same as flying with other people on 2.4. The gopro is much much much closer to the receiver, and wifi uses wider bandwidth and isn't frequency hopping/spread spectrum."

Stuart Brookes replied to Tim Pritts's discussion Need log file analysis help
"Hi,

the mag one is because mag data is not being logged....its not enabled. Therefore the simple test can't run on that data. If loiter is OK, then no need to worry too much other than for curiosity sake.

The second one is due to noise on the Vcc…"

Stuart Brookes replied to James's discussion Thrust asymmetry
"Another good way to check is to look down the end of each arm with the propeller tips pointing at a common point on each adjacent arm (such as the tip of the motor shaft/spinner) and look for a high side, spin the propeller to check its not a bad…"
