Ive only just got the new RFA020 and im looking to replace it with with the (trouble with AXE213 reciever data units). The project i am making at the moment is using a laptop to control a small boat with 2 propellers. the previous thread hyperlinked will explain the information behind this. However is there a way of using the URF to relay information to a PIC connected to an L298D which in turn drives two motors for the propellers of the boat via a laptop. The end product is being able to press one of the directional keys on the laptop which will then be sent to the boats ERF inorder to tell the pic to drive the Boat.
