I few days ago I took this short video of my stock DJI Phantom and stock 3DR Hexacopter on position hold side by side. What I want to share is with the new 3.0 beta firmware Arducopter now performs very similar to DJI on the part where DJI until now has been the best alone.
Being user of both APM and DJI flight controllers it is very inspiring to follow how APM Arducopter gets better and closer to DJI performance for every new firmware release. This new beta release is a milestone for the Arducopter project and the Developers have done a great work with improving the firmware.
From video you can see 3DR Hexacopter performes better than DJI Phantom. Phantom flies good as always. But compared to 3DR Hexa I noticed it moved nervous up and down and around the spot the whole flight. At last Phantom was drifting under Hexa and I ran out and grabbed it to avoid collision (not in video). I think difference in performance may be model spesific, but this show Arducopter now also is very good on position hold!
DJI Phantom from video is complete Stock With the newest firmware release.
Arducopter from video is 3DR Hexa with 880 motors and 11x5 Carbon prop (RCTimer), 3DR ublox GPS, no sonar.
APM 2.5 with Firmware 3.0.0-rc6. All PIDs default from rc6 release.
