Warning #1: Compass calibration and reducing interference is far more important than with 2.9.1b
Warning #2: GPS glitches can cause sudden and aggressive position changes while in loiter mode. You may wish to reduce the Loiter PID P to 0.5 (from 1.0) to reduce aggressiveness (see image below of where this gain can be found in mission planner).
Warning #3: optical flow is not supported but will be back in the next release (AC-3.0.2 or AC-3.1.0).
Warning #4: loiter turns does not maintain altitude. This bug will be fixed in AC-3.0.2.
Warning #5: This release has only been lightly tested on Traditional Helicopters.
Improvements over 2.9.1b include:
WPNAV_SPEED, WPNAV_SPEED_UP, WPNAV_SPEED_DN, WPNAV_ACCEL allows configuring speeds and acceleration during missions
How to upgrade:
1. Make sure you are using Mission Planner 1.2.59 or newer (get it here)
2. Click on the MissionPlanner's Hardware, Install Firmware screen. The version numbers should appear as "ArduCopter-3.0.1", then click the appropriate frame icon and it should upgrade as per usual.
3. Reduce the Loiter and Alt Hold PIDs if you have modified them from the defaults. The modified PID values for the 3DR frame can be seen in the image below.
Note: Nav parameters have been combined with Loiter so do not be concerned if you can't find them.
5. Try out the new version in stabilize mode first, then alt-hold, then loiter and finally RTL and Auto.
Numerous How-To videos are available:
Special Thanks to Marco, DaveC and the large number of testers on the pre-release thread who put their copters at risk during the extended testing period. Some of their videos can be found here, here, here, here, here and here. Thanks also to MichaelO for the MP changes required for this release.
All feedback welcome. Please put your questions, comments (good and bad!) below.
I agree. If the launch location is a bit tight, with obstacles or occasional traffic (humans, other copters, whatever), or just on one of those GPS-glitching days, it might be wise to let the copter hover and land it manually. Not everybody has 100x100 feet or meters shortcut grass :)l
Give my congratulations to Valentina, It's not common to find womens in this activities here in Argentine, I suppose that I'm the only one here flying Quads, mine is a modest HK frame but I'ts my first multirrotor construction, I started with FPV and then APM airplane 2 years ago and last summer with the quad.
What you describe is almost guaranteed to be interference from power distribution board or power wires on the compass. Looking at your parameters from the otherwise empty tlog it doesn't look like you did the compassmot. If you do a flight in stabilze mode and then post the tlogs here I'm pretty sure we will see that it's compass interference but if not perhaps we can find another problem. dataflash logs would be helpful as well.
By the way, about 90% of problem people have are caused by one of the six issues discussed on this wiki page.
your wish is my command. modified with this commit so it'll go out with AC3.1.
I think there are also very good female 3D Helicopter pilots doing amazing stunts (I saw a video on YT). My sister in law was so crazy with my walkera ladybird that I finally gave it to her. My brother on the other hand is not able to cope with the simple ladybirdsteering up to this day - even his 7 year old daughter does it way better.
Anyway.. there should be an initative for women - but how would that look like?
I think like you that is important to post too when the things go well, I did it, so others can read that this update works nice for many people, great work Randy.:)
Please download the MSI from here http://ardupilot.com/downloads/?category=4&sortby=date and install it instead.
hi rendy, we need more details of your problem.
rendy, coba jelasin lagi problemnya gimana. yang detil ya
