Hello,everyone!
My plane 's firmware is Arduplane 3.7.1.When I fly it with FBWA where “the alt=100m,airspeed=20m/s”,my plane’s cruise speed is set 15m/s ,“ALT_HOLD_RTL” is set 75m,that is to say ,if switch to RTL mode ,my plane should fly to alt 75m,but the real phenomenon is big alt lose ,my plane keep falling . When alt is 30m,I switch to Manual to pull up my plane until safe landing.
Can you upload the dataflash log of this flight?
I notice two strange things.
- The MSG message suggests the firmware is “Radius v1.7.1 (22b5c415)” Why is this not ArduPlane?
- The POS RelAlt message shows 0 for the entire flight, despite POS Alt showing values from 125[m] to 230[m]. Why would RelAlt be 0? If the firmware is not actually ArduPilot (as the MSG suggests) then could that be related?
Can anyone coment?
Best,

Thanks for your review!My plane’s firmware is Arduplane 3.7.1. The “Radius 1.7.1” is used to distinguish my plane from others.I give it a name “Radius 1.7.1”.
So why "The POS RelAlt message shows 0 for the entire flight, despite POS Alt showing values from 125[m] to 230[m].“I strongly think it is not related to the name"Radius”,maybe other reasons,I also wander why.
Sorry, I don’t know what would cause POS.RelAlt = 0 for the whole flight, while POS.Alt is non-zero, and BARO.Alt is also non-zero. This might be a good thing to figure out, though.
Can someone else help?
Got same problem too
