motors twitching when disarmed on multishot #540

Closed killaGFPV closed 7 years ago

killaGFPV commented 7 years ago

bf config 3.1.2 bf 3.2.0 spf3 littlebee 35a 32bit esc's br2306 2700kv matek pdb 4s

multishot motors twitch quite a bit and motors are noisy, d-shot 150/1200 issue. number 4 motor has a hard time spinning. airmode must be on to allow even rpm for take off. proshot1000, no result. no response from esc.

This does not sound like a configurator issue. Also, please note that GitHub is for discussion and questions around development of Betaflight. For configuration questions please go to RCGroups: https://www.rcgroups.com/forums/showthread.php?2464844-Betaflight-Flight-Controller-Firmware-Discussion-Thread

I had this... to get round it I went in BF Configurator Reciever TAB set Stick Min to be just above the lowest value on throttle channel with the stick as low as it can go. If this value is not less than the Min set in your ESC then change your TX to lower this value. I have mine at 996 as 1000 is the minimum throttle value on my ESC.

Please, Tx/Rx throttle signal range is completely unrelated to the signal range seen by the ESC. If an analog ESC protocol is in use, the ESC signal range is ONLY the values set in min_command and max_throttle. With an idle value controlled by min_throttle when armed.

thanks! i did that just yesterday, im still having issues with dshot600 and littlebee 35a 32bit esc's one motor refuses to spin. is this an f3 board issue? i built an f4v5pro with omnibus f4 3.2.0 and it works fine on dshot

  1. although i cannot see any of the gui for OSD in betaflight configurator. i can however see the gui in cleanflight with betaflight installed. but setting changes are not saved. the f4v4pro on dshot 1200 did however flip out on me once when i punched and zero throttle stall and punched again from 0rpm.
