Out of control yaw spin

[Baz Tidbury]

Ok I out out of ideas,can anyone shine a light on this.x220 wizard,was flying absolutely fine.the next time it took it out I went to take off and it just went into a yaw spin and crashed on take off.it does  this all the time now.betaflight is updated,props on correct,tried reflagging board and recalibration and still no joy.with props off it’s fine but put props on and spin the motors up and it’s like it’s stuttering.i tried switching to acro mode and on take off it flew straight up at full throttle and had to kill the motors.confused [emoji848]

Most common causes:
(Ignoring props wrong way round)
Check yaw motor direction checkbox in Top left of config tab is correct
(I.e. check without props that motors spin in the expected direction)

Check stack build, broken standoffs, not properly tightened down, soft mounting too soft, or just non standard/stable stack builds

Flash an older version of bf - the devs have been working on YSTTM (yaw spin to the moon) and still haven’t got it licked, v3.1.7 should be safe

My bet is the first one

has this been solved? if it flies and suddenly goes nuts, have you done a range check? maybe rx antennas got damaged

Problem with Rx antenna will not produce this, it will produce failsafe.

Il upload a video in the next couple of days so you guys can see exactly what’s going on

With all four props off, do all four motor spin and in the right direction?

I think Cheredanine mentioned this but I had a similar problem last year and it turned out to be broken fc stand offs from a crash just before.

I gave up on it in the end.ive another wizard coming as they were on sale with 40% off.i now have one for spare parts as I’m bound to need them and saves being out of the air while waiting for spares
