Based on people tests and results with rc1, what is the schedule date for the rc2 release?

It’s hard to predict dates… I think it’ll be a week or two. I’d expect it before June 25th.

any new information on the release schedule? i’m not confident with proceeding to test on rc1 (auto and gps modes) do you rec to install a daily build or wait till rc2 release?

There’s update about ac3.4.2 ?

So I personally hit a delay with the ADSB stuff. I think there is just one more item to get into master before we can push out -rc2 so I hope to do that this week (I hoped to do that last week actually but…).

Great! I can’t wait to load it and test:
- RTL after "fly here {Serious problem altitude wise in 3.3.3}
- Moving base (Insuring RTL return to base and not to launch) {Rally points}
- RTL after follow me {Altitude mentioned in parameters NOT ABSOLUTE}
So bring it on please…

It’s on it’s way out now. Hopefully it will appear in the mission planner’s Beta Firmware link in about an hour or two. The full list of changes are in the ReleaseNotes.txt file but I’ve also copied them below:
Changes from 3.4.0-rc1
- ADSB based avoidance of manned aircraft
- Polygon fence (works seamlessly with circular and altitude fences)
- Throttle related changes:
a) motors speed feedback to pilot while landed - motors only spin up to minimum throttle as throttle stick is brought to mid (previously spun up to 25%)
b) MOT_HOVER_LEARN allows MOT_THST_HOVER to be learned in flight
c) THR_MIN becomes MOT_SPIN_MIN
d) THR_MID becomes MOT_THST_HOVER - Precision landing:
a) control improved by reducing lag from sensor and correcting math errors
b) descent rate slows to allow time to correct horizontal position error - Guided mode:
a) velocity controller accelerates/decelerates smoothly to target
b) Guided_NoGPS flight mode added to allow companion computer control in non-GPS environments
c) stop at fence if using velocity controller, reject points outside fence if using position controller - Throw Mode:
a) THROW_NEXTMODE parameter allows copter to switch to Auto, Guided, RTL, Land or Brake after throw is complete
b) Throw mode fixes so motors reliably start - Attitude controller:
a) use Quaternions instead of Euler angles
b) ATC_ANG_LIM_TC allows controlling rate at which lean angles are limited to preserve altitude in AltHold, Loiter - EKF can use range finder as primary height source if EKF2_RNG_USE_HGT parameter is set to 70
- Bug fixes
a) AutoTune fix so that gains don’t fall too low
b) Rally points with altitudes no longer cause vehicle to climb above fence during RTL
c) various EKF fixes including bug in initialisation of declination co-variances
d) SingleCopter, CoaxCopter flag gains - Small enhancements:
a) Rally points outside fence are ignored
b) AP_Button support added to allow ground station to see if user has pushed a button on the flight controller
c) support for PLAY_TUNE and LED_CONTROL mavlink messages to cause vehicle to play tune or change colour of LED
d) support for GPS_INPUT mavlink message to allow supplying vehicle position data from other sources
e) NAV_DELAY mission command to delay start of mission (or individual command) until a specified absolute time
e) TKOFF_NAV_ALT param allows take-off with no horizontal position hold until vehicle reaches specified altitude (intended mostly for helicopters)
f) SCHED_LOOP_RATE param allows slowing main loop rate from default of 400 (intended for developers only) - Safety (in addition to Fence improvements above):
a) Motors begin spinning 2 seconds after arming (previously motors spun immediately)

Fly with Pixhawk by 3.4-rc2, it became much stable and no yawing problem. I have to hold comment on NAVIO waiting for release of 3.4-rc2 by EMLID.
Thanks Hattori-san for testing!
