I remember some years back there existed a web based turning simulator where numerical values such as P, I, D, IMAX, etc could be input along with the drone's mass.  The drone could then be flown vitually to visually look at how various tunes would…

I was looking on the 3DR website for a radio kit but I wasn't able to find one listed anymore.   Does 3DR still make and sell radios for those of us who build our own drones?    I sure hope they continue to do so into the future.

David replied to David's discussion Quadrotor X4 vs X8 in Code
"Thanks James.   This is insightful information.    When all Yaw tuning parameters are set to zero (desktop test with motors off), the magnitudes of the top and bottom motors on a single arm for the X8 are the same PWM values.   I looked at this via…"

David replied to David's discussion Mission Planner Starts Speaking String of Digits Upon Connecting with Pixhawk
"Thanks for the feedback.   This makes sense that it is some sort of serial number.   It surprised me since older versions didn't call out the long string of numbers at start up which made me think it might be a problem."

I have a couple questions about how Arducopter handles the X4 configuration vs the X8 configuration.   What are the differences?  Is the X8 the same as an X4 with identical signals sent to the top and bottom motors?  Is there anything special…

David replied to David's discussion Arducopter X8 Multirotor; X Configuration vs Plus Configuration
"Quick update in the hope it may help someone:  I determined through experimentation that Arducopter does support the plus configuration for the X8 by changing the parameter directly."

I am building an X8 Multirotor.   I would like to use one of the arms as the front facing direction.   Does anyone know if Arducopter supports the plus (+) configuration or must we use the default X configuration only if flying an X8 octacopter?This…

David replied to David's discussion 3.1 Sudden Violent Crash while in Loiter
"A little more info- the initial rocking back and forth seemed to be started by the wind.    After the oscillation started, it seems as though the APM may have over compensated the recovery?    Thoughts?"

I was flying my Steadidrone Qu4d running APM 2.6 (Arducopter 3.1) when I experienced a sudden loss of control and crash while in loiter mode.   I had been flying in auto mode with waypoints and switched back to loiter.   Everything was performing…
