I was wondering if anyone could help me with this problem.....this is what I got going on.....I bought a Futaba 3PK with 2.4GHz....I have two r603fs receivers....I got one in a car and it works fine got all the settings right and then I tried to set the seconed one up. So when I get into the M-SEL on the controler it comes up with the one car but wont let me select a new model so I can bind it to the new receiver, its like its locked can move around just cant enter on one of the models.....is there something I am doing wrong or is it my controler....thanks for your time hope you can help
