For Sale: Like new Canon SX260

Bought an SX260 a while ago for mapping, but never ended up using it beyond a couple quick test flights.  Like new condition. Complete with box, etc.  These are sought after because of CHDK and NDVI…Continue

"Well, I'm interested to learn more.  How was the 99.9999999% reliability proven?  As Tom alludes to, that is a lot of testing time.  I should think this system would end up costing somewhere well north of $100,000? Tom, to get…"

Robert thanks for your input the 1/8 aluminum on  on the fuselage will be a milled out channel running  half way down the side of the plane    to attach the wing the horizontal stabilizer and the vertical fin to a Exoskeleton about 1 1/2 pounds the rest of the plane is foam and fiber glass there was no distortion welding we had it clamped down  pretty good Thanks again Carl

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!
