Rover brushed esc wants to full throttle upon power up

Open tnap1979 opened this issue 4 years ago • 2 comments

mateksys f722 wing edition flight controller, Matkesys m8q-5883 gps/compass, 128x64 oled display, Crossfire diversity nano receiver Tamiya teu - 106bk dual brushed esc with dual 45t 2magnet/pole motors Integy scx10 custom 4x4 crawler frame Molicel 21700 4200mah 45a li-ion in 2s2p

Hardware all works perfectly but as soon as I power on the esc, it beeps twice and seems to go full throttle Running latest inav release from configuration app on surface pro 6 w/windows 10 pro .. I cant configure the esc either, seems like inav isn't allowing the radio information to pass thru to the esc to try to calibrate it

What sort of TX are you running -- is it a stick radio? If so: it's possible that your full stick down (on throttle) isn't registering mentally as "WOT in reverse" in your brain. Should this make sense, you can set up a mix w/ two throttles

  • one w/ 50% weight and 50% offset
  • another with -50% weight and -50% offset
    • be sure this second one (and only this second one) is conditional on a switch being thrown (I personally like SA ⬇️ )
  • both of these should output to your throttle channel

Do some testing w/ the pinion off, or disengaged from the spur at least.

Apologies if my hunch is an irrelevant tangent. An aside, INAV is really not set up to make rover stuff straightforward (especially when it comes to nav params & the very low signal-to-noise ratio the configurator presents us with, despite it "knowing" that a rover is the intended use case).

If you have the motors / ESC on a servo output, and you have it set to bidirectional, that would explain it. If that's the case, changes will be needed.
