Evan Coasts commented on Hugues's blog post 1h:15min flight time - Airbotservices X4 with brushless gimbal & fullHD camera on 12mm rail system
"Great achievement! Congrats!
Can you share specs of motors, ESCs, propellers used?  
What is the weight of the overall drone and of the battery alone? "

Evan Coasts replied to Randy's discussion Copter-3.3 beta testing
""support do-set-home command (allows return-to-me and locked home position once GCS enhancements are completed)"
Can somebody provide some information on this specific feature above (10.a)? Is this implemented and its currently usable? If not, then…"

Evan Coasts replied to Michael Hadsell's discussion Understanding Altitude setting for APM and Mission Planner
"Note that according to this: http://copter.ardupilot.com/wiki/common-terrain-following/
terrain following applies only to arduplane, not copters yet. So don’t count on this feature for automatically adjusting your altitude if you fly a copter. "

Evan Coasts commented on elad orbach's blog post Sony camera controlled with RC transmitter
"Hi Elad,
I looked at the Visca protocol and there is actually a command to send preset zoom positions to the camera. The command is called “Cam_zoom direct” and it is described on page 31 of the document you provided. Cam_zoom direct: 8x 01 04 47…"

Evan Coasts commented on elad orbach's blog post Sony camera controlled with RC transmitter
"Excellent work and documentation! A very useful project for the community.
I was wondering if there is a way to control the camera zoom level i.e. x2, x3…etc, by sending absolute PWM values for each zoom level. That would certainly be a huge added…"

Evan Coasts commented on Hunter Parris's blog post Overlaying GPS Coordinates for Camera Crosshairs
"It all comes down in solving the camera pointing algorithm in the reverse order, as Lucas suggested. Within this algorithm there are three variables:
1. Own (GPS) position, altitude
2. Target position, altitude
3. Pant tilt X and Y values. X for pan…"

Evan Coasts commented on Hunter Parris's blog post Overlaying GPS Coordinates for Camera Crosshairs
"These guys are doing it already for quite some years now as far as I know: http://magnetsystems.net/
They provide the coordinates not only of the crosshair location but from every pixel of the video window. An impressing technology called video…"

Evan Coasts replied to Andrew Tridgell's discussion ArduPlane 2.50 released
"Hi,
 
I’m trying to locate where into the new APM 2.5 code, the compass calibration routine is.
Can somebody provide some assistance?
 
Best regards
Evan "
