Thanks Airboss

I tried it like that first, but same prob.
This is from the hacker website suggesting optimum timing for AXI is 30deg.



Timing Mode 1 – (2-5 degrees) optimum timing for Hacker Brushless Motors
Timing Mode 2 – (10 degrees) optimum for Aveox or Astro motors and for
Maximum RPM on Hacker Brushless Motors
Timing Mode 3 – (18 degrees) optimum timing for Phaser, Mega, Plettenberg and for Maximum RPM on Aveox, Astro motors
Timing Mode 4 – (30 degrees) optimum timing for AXI, Köhler or Actro motors and for Maximum RPM on Phasor, Mega, Plettenberg motors
