I need help on wiring my controller for my RC boat to the velleman k8055 VM110. I followed the instructions from one of the sites which uses RC cars found at ozirocks.com but i did not achieve the same result. Whenever I connect the wires for the four direction of the boat and the ground to the velleman the boat goes crazy. What I mean to say is that it randomly does one of the four direction. Sorry for my english. I really need help on this. Does it mean I cannot connect the controller in parallel with the four digital output of the velleman? Thanks in advance.
