I am going to be flying with the JR sport s 400 radio that came with the trainer. If I have to use seperate channels for the ailerons, can I do that with this radio? It isn't a computer radio. It is a four channel radio. Or am I going to need to go with the y harness? I bought the arf version of the plane, do you think it is going to come with a y harness? Thanks for all the help. Matt
