For those of you using a FrSky Horus 10/12 with APM will soon be able to use a new Yaapu Widget mapping feature from Alex Apostoli. This is still experimental but seems to be working on my transmitter. Any three position switch can be assigned, in my case SA, to change between the normal main HUD, MavLink Message screen, and Map screen. Shown below is the map screen from my house which requires the GPS sensor to be discovered through Ardupilot. A second zoom switch, in my case SB, can be assigned to change the zoom from three different levels.
For long range fliers, the GMapCatcher User Wiki shows you how to set a path and then download the area maps that would be included in a visual path. Shown below is a 100km path from my flying field in Rochester, NY to Niagara Falls. Buffalo, NY is just below and Toronto, Canada is on the upper left.
I don’t think the Horus can do a screen snapshot or I would post some images from the field. The new mapping feature adds convenient position tracking right on your transmitter screen. It can be used with or without a GCS.
