Hello pug398 or other Taulabs masters:
Thanks so much for the help.
Does anyone know what the reason the preset altitude is or has to be 15m? As I know in OP Revo, the default value for RTH is 10m, and it can be changed. It is a little scary to rise the quad up so fast in a very short time.
I saw the footage by AlPackin on the Youtube: https://www.youtube.com/watch?v=TUJB3ex5P2o
It was very nice, but the altitude or speed seems too fast for the novice like me.
Is there any way to setup new altitude and speed for RTH? I can't find in GCS/System.
