Dear Mr. Lefebvre,

I saw some videos from your heli in Loiter Mode and thought wow this heli is standing rigid in the air.

I'm using a TREX 700E and want to fly this heli with apm 2.5 version 2.91 autonomously.

Currently I want to adjust the PID parameter. The stabilize and the Altitude Hold Mode is working perfect, but I have some problems with the Loiter values.

So would it be possible to send me your PID values of the loiter mode? I think they have to be very similar.

Thanks.

Nice Greets from Austria

Hi Mr. Lefebvre, 

Thanks for getting back to me.  Do you have any suggestions in terms of renting or hiring aerial videography crews or drones?  

All the Best, 
Jon

Hi Rob,

Interested in making a Tandem out of 2x 800 sized helicopter. Just interested to discuss your thoughts.

Hi Rob, I saw your DroneCon talk on youtube (which was great, thanks!), and it looks like you got cut off towards the end there. By any chance is the full slide deck available somewhere? Or was there much more left? Thanks!

Hi Rob, i know you had a lot to do with AC yaw control, could you confirm if motor values are used in the formula for the yaw servo control? In other words if running a motor in a wrong direction would affect the yaw control. If so is this something that appeared in the code since 3.1.3 or was it there before? Thank you!
