After sucessfully flying in altitude hold mode for a couple of weeks, yesterday the altitude started spiking while in hold mode. The altitude just keeps randomly pulsing higher. I am using sonar (MB1200 XL) and the signal from the sonar seems steady while on the bench attached to the computer.
Up till now Alt Hold had been working flawlessly both at low altitudes and higher.
I believe I am using the latest firmware.
Can someone tell me what to look for?
