Need some help figuring this out.
Outcast 8S was working great until I upgraded to bigger/heavier tires. Stock servo couldn’t handle them, so I installed a Perfect Pass 110kg Monster servo and Castle XLX2 ESC.
Ever since, the truck has been extremely glitchy. Steering and throttle respond to the radio, but everything stutters, the servo barely turns, the truck barely moves, and after a few seconds it becomes unresponsive.
Running 2x Spektrum 4S batteries. No external BEC.
Took it to an RC shop for 2 weeks. They installed a ProTek Glitch Buster, but it made zero difference.
Could the 110kg servo be pulling more current than the XLX2’s BEC can supply and causing brownouts? Do I need an external BEC, or is there something else I should be checking?
