Since we are still learning all of this R/C stuff, I need to ask a question that is probably easy to answer. We so far have 3 cars. 2 of them are running with 2.4 TQi rx (6518) and 1 is a 2.4 TQ rx (6519). We have 1 TQi tx (6509) and 1 TQ tx (6516). Can these all be bound so that both tx will work with all of the cars (depending on which one is powered on first) or do we need 2 TQi tx's ?? I have the TQi tx working all 3 cars, but the TQ tx will only work the TQ rx if it is rebound to the TQ tx, and then we have to rebind the TQi tx again to make it work later. I guess what I am trying to ask is ..... Can a TQ rx be bound to more than 1 tx at a time like the TQi rx's ??? I would like to end up with 3 Tx's that will control 3 different rx's without having to rebind everything everytime we switch out cars or radios. Hope this isnt too confusing and thanks for any help !!!!
