I replaced my brushed motors and ended up with a evx-2 blinking green light.
So i bought a brushless castle/motor combo and get the same blinking green light.
After a few days of troubleshooting i found that switching the esc and servo cables will run the motors on both the evx-2 and the brushless set. i can run the erevo with just the steering wheel, but throttle trigger does nothing.
