Must look into manual didn’t know I could switch off mixers. Outputs in all channels set at max motors are identical and fitted on bench have also tried on boats 2 x 600 2 x 400 and two geared motors all identical pairs 2 different kinds of esc’s. Have tried with throttle and aileron, throttle and elevator, and throttle and rudder always the same one motor first and it is always from the esc that is suppling power to bec the other esc has red wire disconnected. I have now tried four different mixers all the same.and followed all the instruction on them.
All work good on the turnigy which has had no adjustments made to it. That is why it must be in the spectrum transmitters as the 6i has the same problem.
Elsrickle is the small village where I was brought up.
Many thanks must get the mixer switched off
