HowTo Use

Lets make an example: You like to have a warning when you LiPo is going empty.

  1. You have to set Limit / MinPowerVoltage
  2. You have to enable Warning / MinPowerVoltage

In Action

HoTT Multicopter Screen

Indicator 1:

  • ' ' no GPS configured "Dir:" shows "you," the orientation of the compass (otherwise the direction of flight, not the orientation)
  • '!' GPS-Error (like red GPS in GCS)
  • '?' GPS-Warning (yellow, GPS data is there but inaccurate)
  • '.' GPS-OK (green, ready for navigation)

Indicator 2:

  • '-' no Home position (you should NEVER! set the home position in gcs)
  • 'H' Home position triggered. Now 'RTH' is possible. It still recommends taking a look at the distance and the home course before you try this. 'PH' of course works better when the number of satellites is large or a '.' next to it.
