Hi I took the advice which was very much appreciated and bought one from Rory mangles, I also bought the cheap one from eBay to setup with as I'm new to this and didn't want to blow a £55 esc. The eBay one only has one 3 pin cable to connect to the Rx and when I connect to ch3 of rx I get both motors turning fine when I push left thumbstick forwards however it doesn't respond to left and right inputs. If I connect to channel 4 the motors spin when I move thumbstick left and right. The Rory mangles esc has two 3 pin connectors so I guess my question is how does the eBay one tank steer with only one 3 pin cable?
