Each of the pics below have had the Safe Rx added to them. I have also added a pic of one of the few ESC’s that are not from eflite. The other esc that I am aware of is the Thrust brand from HK, as well as some of the ones that come inside a multiplex plane.
Its not untypical to have to reverse a servo since the output of the Rx does not allow reversing a servo when output is sent from the Rx. In a case like this, you must use a servo reverser (radio has no effect). Most of these planes have the turnigy servo reverser on at least one servo, however there are times when you can physically move the placement of the servo to allow reverse.
Recently, I have started opening the servo and reversing soldered wires to create the opposite action (2 potentiometer wires and the 2 motor wires are reversed and resoldered)
This is a Hobbyking ESC that I have had success with.
