We're within a day or two of releasing ArduCopter 2.6.1 to the public in the Mission Planner. It's the best performing code we've flown and the waypoint accuracy is really impressive. You can check out Marco Robustini's video above to see an long-distance waypoint flight, some tight loiter at 5:30 (holding in a 1m box!) and a fun demo of autorotation.

A full list of changes is here, but they include:

 

Performance improvements:

  • Better loiter, especially with the new 3DR uBlox GPS. Check out the video from Marco above!
  • Better yaw control
  • Better DCM implementation, resulting in noticeably smoother flight
  • Better camera control, including improved setup in the Mission Planner.
  • Etc

Bugfixes:

  • Fix to dataflash erasing, which should resolve an issue some users were having
  • Fix some MAVLink commands
  • Fix Circle command
  • Fix some units
  • Etc

Yes, i use "autorotation" term for fun, actually the quad has a minimum of gas (1% of throttle), that little need to keep the propellers in motion, but during the fall "the pinwheel effect" makes accelerate keeping stable the quad.
This is possible only if the quad is perfectly balanced and if the pilot knows what he does... :-)
Sorry for the language mistake, yes, 300 meters,
but considering the autonomy that I have the next waypoint will be far more than 1 Km.

Chris,

Sorry for the confusion.  Last time I emailed sales "Chris" responded and for some reason I assumed it was you.

New caméra control use output channel 5 to 8. How to use output 9 to 11 with input 5. Like previous camera control?

great testing marco, a quick question, i today rec3ived my order of 3 x new ublox gps units, one for the quad, hex and octo each, 2 of the 3 work flawlessly but the 3rd seems to not, when powering up the board, it takes alot longer for the apm2 to initialize, like 20sec or so, after wich the blue gps led does not come on at all, gps leds are on and blinking but nothing on apm, replace with different ublox and perfect again.. any ideas??

No Duran, but I think it's a defective unit or not properly initialized, try to connect the gps with the U-Center with a FTDI cable...

Comment by Duran - ALTI on July 18, 2012 at 11:10pm

U-Centre ? link ? FTDI cable, this the same as the 3DR radios use ?

Clarification of Flip Mode please?

Comment by Aaron Curtis on July 19, 2012 at 6:45am

Graham, flip isn't actually a mode. It's a channel 7 option. http://code.google.com/p/arducopter/wiki/AC2_SimpleMode It needs to be enabled in the code, by uncommenting in config.h  . The mission planner does actually have it in the CH 7 dropdown box, but I don't think it works unless you edit config.h and compile the code yourself. I imagine that once a few more people have tested it you will be able to use it with the standard .hex that Mission Planner loads onto the copter for you.

Hi guys... I am actually anxiously waiting on AC 2.6.1 because I have one of the APM2s with the EEPROM erase problem. What is the current ETA? Should I rather go for self compilation?
