"Jean.louis I need a little help from you.
I've made other tests, and I've notice one thing.
If I give a value of 70 (this is the value where the rover start to go) instead of 50, as I switch in automode, the rover start to go immediately with very…"

"Hello Jean-Louis,
THROTTLE SLEWRATE RESOLVED!!!!!!!!!
The mistake was due because of this line in Attitude arduino file:
g.channel_throttle.servo_out = constrain(((float)throttle / 10.0f), 0, g.throttle_max.get());
Where 0 we need to change with 50.…"

"Hi Jean Louis,
I've made other tests: if you increase the values until 100, the rover start to decrease the backwards distance. At 100 the Rover go backwards for 5 cm or less and then start to go frontwards fast. It's obviusly that the inversions of…"
