Electronics problem

[V-Rossi]

I have installed a brand new Speed Passion GT2.0 Pro, Savöx SC-1251MG servo and Spektrum SR3500 micro receiver in my offroad car. ESC works perfect, but the servo doesn't get any power.
I tried another servo and again it didn't do anything. Then I tried an SR3001 standard Spektrum Pro receiver after which nothing worked, the ESC gets the current, but the servo again doesn't.

Could this be a radio problem? It is a Futaba 3VCS with Spektrum Pro.


Cheers,
Jorg.
