This is a list of issues discovered during ArduPilot 4.6 testing. Issues for [C…opter/Rover-4.5 issues are here](https://github.com/ArduPilot/ardupilot/issues/26103)
**Reports requiring investigation**
- [ ] QuadPlane EK3 velocity divergence before arming ([issue](https://github.com/ArduPilot/ardupilot/issues/29384))
- [ ] CADDX GM2 update slow ([discussion](https://discuss.ardupilot.org/t/copter-4-6-0-beta4-released-for-beta-testing/130471/38))
- [ ] iBUS telemetry not working? ([discussion](https://discuss.ardupilot.org/t/copter-4-6-0-beta2-is-available-for-beta-testing/127445/11))
**Confirmed issues**
- [ ] Unknown message 45 ([discussion](https://discuss.ardupilot.org/t/copter-4-6-0-beta4-released-for-beta-testing/130471/43), [discussion2](https://discuss.ardupilot.org/t/sending-unknown-message-44-on-mission-planner-with-speedybee-f405-v3-guided-mode/130303))
- [ ] TradHeli internal errors 0X4000000 and 0X4000020 ([discussion](https://discuss.ardupilot.org/t/copter-4-6-0-beta4-released-for-beta-testing/130471/23), [issue](https://github.com/ArduPilot/ardupilot/issues/29370))
- [ ] Holybro M10 waiting to configure GPS1 ([discussion](https://discuss.ardupilot.org/t/fc-tries-to-config-gps-constantly-when-trying-to-arm-in-loiter-mode/129930/7), [PR](https://github.com/ArduPilot/ardupilot/pull/29320))
- [ ] on ICM45686 IMUs the SPI transfer overheads can be overwhelming on some boards, especially those with 3 of that sensor. Some PRs to address: https://github.com/ArduPilot/ardupilot/pull/28672 and https://github.com/ArduPilot/ardupilot/pull/27573
***Plane Specific Issues***
- [ ] the assisted_flight flag oscillates rapidly in fwd transition of tilt quadplanes, possibly leading to incorrect tllt slew rate https://github.com/ArduPilot/ardupilot/issues/28957
***Heli Specific Issue***
- None
***Wiki Issues***
- [IMU temp cal pages](https://ardupilot.org/copter/docs/common-imutempcal.html) need updating
**Enhancements or Issues that may not be resolved before the stable release**
- [ ] BLHeli SERVO_BLH_RVMASK mapping is achieved through trial and error (raised by xfacta, [issue](https://github.com/ArduPilot/ardupilot/issues/29325))
- [ ] when the user has configured ESC, FFT or RPM notch and has INS_HNTCx_REF=0 then they end up with a fixed notch. We should have an arming check to tell them they need to set the REF to 1.0 (any non-zero value will do actually) https://github.com/ArduPilot/ardupilot/issues/28786
- [ ] ROS2 attitude control + thrust enhancement request ([discussion](https://discuss.ardupilot.org/t/ros2-interface-for-controlling-thrust-and-attitude/127694))
- [ ] AutoTune should have a vehicle specific (or configurable) AngleP max (reported by Tridge)
- [ ] add a warning if the GCS system clock and UTC clock on the flight controller differs by over 20s and signing is active, as signing will fail with a 30s difference
- [ ] Custom Build Server for CubeOrangePlus with OpenDroneID shows linker error when out of flash ([discussion1](https://discuss.ardupilot.org/t/copter-4-6-0-beta1-is-available-for-beta-testing/126295/4), [discussion2](https://discuss.ardupilot.org/t/copter-custom-firmware-build-issue-with-remote-id-support-latest-not-4-5-7/125177), Issue)
- [ ] Add LDRobot LD19 support ([discussion](https://discuss.ardupilot.org/t/copter-4-6-0-beta1-is-available-for-beta-testing/126295/8), [issue](https://github.com/ArduPilot/ardupilot/issues/28662))
- [ ] need to provide a clearer message to users when the power status flags change, indicating loss of a power source in flight. A statustext at message level CRITICAL I think is warranted, maybe "POWER STATUS CHANGE" ? (Tridge has details)
