I did a continuity check on the receiver lead and that is OK. Looks like there is no simple fix. I am not sure if I should send this in to get repaired or just buy a new Monster X. The X has a lot of usable features like all the leads come out the top, the servo, power switch and fan are on a harness so it is easy to repair a pinched lead, sensored/non-sensored control, 6.5 mm bullet connectors to the motor, aux channel that can be used for anything but I like to use it for enabling/disabling reverse for practice/racing ...
I wish Tekin would make this decision easier by adding some value to their side of the equation.
