Futaba Brown Out Issues

I have 4 cars (3 x 1/10 offroad and 1 x 1/10th onroad) each with Futaba receivers and Savox servos. I have had intermittent ‘brown out’ issues with all of them. I have fitted Futaba capacitors to all of them, and this seemed to fix the problem. However, with my 2WD and 4WD buggies, the problem is back. I have had 2 different esc’s and motors in both cars so I’m sure it’s not those. I have cleaned battery terminals, checked all wires, changed sensor wires, recalibrated esc’s. I spoke to some guys at the track and they said that it sounds like a transmitter issue. Anyone else had a similar experience to this? TIA.

Try asking in the dedicated forum. Radio and Electronics - R/C Tech Forums

What is the servo requirements for voltage vs what your esc can provide?

What kind of servo and ESC are you running? If it's some insane torque servo on an ESC with a 3A rated BEC then no amount of capacitors will do the job. Also are your endpoints set properly to avoid the servo trying to run past full steering lock?
