标题: APM重大升级版即将发布：ArduCopter 3.0-rc1来了
ArduCopter 3.0-rc1 (release candidate #1) is now available in the new downloads area. Alternatively you can download the zip from the github site here or finally click on the Mission Planner's Firmware screen and click the "Beta firmwares" link which will temporarily change the versions that are downloaded for each frame type.

ArduCopter 3.0.0-rc1 improvements over 2.9.1b:
1) Inertial navigation for X & Y axis (Randy/Leonard/Jonathan)
2) 3D waypoint navigation library (Leonard/Randy)
WPNAV_SPEED, WPNAV_SPEED_UP, WPNAV_SPEED_DN control target speeds during missions and RTL
WP_YAW_BEHAVIOR to allow disabling yaw during missions and RTL
3) PX4 support (some features still not available) (Tridge/Pat/PX4Dev Team)
4) Safety improvements:
Tin-can shaped fence (set FENCE_ENABLED to 1 and copter will RTL if alt > 150m or horizontal distance from home > 300m) (Randy/Tridge/Leonard)
GCS failsafe (set FS_GCS_ENABLED to 1 and if you are using a tablet to fly your copter it will RTL and return control to the radio 3 seconds after losing telemetry) (Randy)
pre-arm checks to ensure accelerometer and radio calibration has been performed before arming (Randy)
5) motor interference compensation for compass (Jonathan/Randy)
6) Circle mode improvements:
set CIRCLE_RADIUS to zero to do panorama shots in circle mode (copter does not move in a circle but instead slowly rotates)
CIRCLE_RATE parameter allows controlling direction and speed of rotation in CIRCLE mode and LOITER_TURNS (can also be adjusted in flight from CH6 knob)
7) SONAR_GAIN parameter add to allow reducing the response to objects sensed by sonar (Randy)
8) support for trapezoidal quads (aka V shaped or FPV quads) (Leonard/Craig)
9) performance improvements to dataflash logging (Tridge)
10) bug-fix to analog read which could cause bad sonar reads when using voltage or current monitor (Tridge)
11) bug-fix to motors going to minimum when throttle is low while switching into Loiter, AUTO, RTL, ALT_HOLD (Jason/Randy)
12) bug-fix for auto disarm sometimes disarming shortly after arming (Jason/SirAlex)

There are already a number of known issues that have been added to the issues list:
a) sometimes the copter jerks severely when first entering loiter, RTL or reaching a waypoint.
b) spiraling around a waypoint normally caused by your compass heading not agreeing with true north
c) too many nearly empty log files produced
d) climb and descent speeds during RTL or missions can be very slow
e) accelerometer calibration through mission planner can required multiple clicks of the button

A couple of warnings -- it's only release candidate #1 (there will be at least 1 more before the official release) so it's still a work in progress. I won't be able to analyse every log posted because I also need to spend time on fixing up the known issues. Still, all feedback both positive and negative (so we can get the issues resolved) would be greatly appreciated.

除了软件功能的不断改进，3.0最重要的特性是对PX4硬件的支持。

我已试飞px4的2.9.2beta固件，手感很不错！http://bbs.5imx.com/bbs/forum.php?mod=viewthread&tid=778422

接下来，我计划用S800+PX4试飞3.0固件，哈哈，大家拭目以待吧。

那我刚团了个2.5的板子岂不是有些浪费啊

贵是有道理的，px4是两块板子，io板也有cpu，还有高品质的电源模块

很希望可以试试，我想先做几块板子看看
有需要的联系我。QQ:272787490.大家分摊，成本低点。
