My Mad Bull just beeps… 1 year 8 months ago #72110

Hi,
I am trying to get my Mad Bull to work for my son, but it just beeps when I turn it on. Batteries are all well charged.
Also, when I turn it on the steering servo rotates clockwise and continues trying to turn.
Any help would be appreciated.
Cheers,

Sounds like no signal being received. What's your setup? Pics may be better than a description:)

Servo has gone bad, replace.
Had several going bad on me in the past, mainly on crawlers. Some of them just turn sharply to one side and will not return.

Beeping signal is a hint the receiver lacks input signal.
On the receiver, steering servo cable goes into channel 1, and throttle speed controller or servo for the mechanical speed controller into channel 2.
Make sure all the negative wires is pointing to the outside of the casing. That wire is either black, brown or orange depending on the brand.

If you need to replace the steering servo, make sure to turn on the system first and set the trim to zero on the transmitter before fitting the servo saver.
