Title: Quick question on throttle channel
Post by: Jarredw on November 30, 2016, 08:37:00 am

I was curious what the neutral value for throttle was for? I get the others equate to when the controls are centered. My value has always been a touch above the minimum.

Neutral is set to the slowest speed where the motors will run reliably.

Thank you for the reply. I was curious about the neutral setting for the throttle channel on the input tab though.

Hi,

Every channel input is scaled to a -1 / 0 / +1 range so whatever the input type and min/max/neutral values, after the scaling all inputs are know as -1/0/+1 in code.

(https://forum.librepilot.org/index.php?action=dlattach;topic=2690.0;attach=4704)

For safety reasons the -1 (min throttle) is needed for arming, the Throttle neutral value is set around 4% of the whole stick range.
If you set the throttle neutral like others you get only a half stick range used for throttle.
