DOMINO Throttle and VOTOL EM 150- 2 pairing problems

[fredooo]

Hi , i have some troubles pairing the Domino Throttle with the Votol controller , at first it was ok and quite responsive turning the throttle ( similar to a gas throttle) but after a couples of runs the delay in the response went higher near the middle of the rotating and sometimes not responsive for a moment ,the maximum voltage obtained ia around 3, 85 volts .I thought first it was too much resistance and change the wires from 22 to 16 but no change. Some body had an experience with that throttle / controller? The motor is a QS 138 70 H with gear reduction and battery 20 S 6 P Molicell P42A
