So 1 way communication and 2 ch. is what you want.
I was going to go 1 way 2 channel, but it seemed that channels 3 and 4 did not have voltage to power my motor fans and transponders. Set the NB4+ to 1 way 4 channel for that reason. Have to check this again. Probably will still need to bump up the BEC voltage from 6v to 7.4v to regain servo speed. On an indoor clay track, my B7 and B74.2 CE steering is definitely slower compared to my ailing M17. I plugged my B7 back into my Sanwa receiver and with the M17 the steering response was more sensitive and faster compared to the NB4. Maybe I messed up somewhere 🤔 Appreciate your response.
