Hi Everyone,
I’ve just completed the build of my first FPV. I set up my transmitter (an old Futaba T7C) and ESC with Betaflight 4.1.1. I’m facing this annoying problem that I couldn’t get around:
When testing Throttle function (gradually sliding up), one motor “jumps” to maximum speed. The rest are spinning “slowly” (around 1200). In addition, if taking the throttle up (above 1200) motors are still spinning the same (one at max speed, and three slowly). Plus, from this point, sliding the throttle down make no change in motors speeds. Only dis-arming the quad stops the motors.
Would appreciate any ideas…THANKS

it sounds you try it without rotors? i guess throttle down and so decreasement is normaly without rotors
different spinnig speed shouldnt be, is it the same if you spin them in motors tab?

what motorprotocoll do you use?

Hi,
Thanks for your suggestions.
I actually tried once WITH prop's...it was disaster, since I couldn't control the speed. From very low point of throttle motors got very high spins...
When testing motors via Betaflight all seems normal; motors speed and transmitter's values (i'm using an old Futaba 7TC).
As for motor protocol, I use "ONESHOT125"...but tried some others
