Hello:
I am having an issue with my 203GF receiver using my 3PV radio. The problem is, after binding a second receiver to another car, both cars will operate simultaneously when both are on. I created 2 individual profiles (model names) and they work fine when I switch back and forth but if both cars are turned on they will both operate. Did I do something wrong? Thanks for any help.

Nothing wrong, just turn one receiver off. If you had 10 cars; each receiver bound (binded? ) to the same transmitter, and they were all turned on at the same time, yes, they all would be reacting to the transmitters output. Each car's unique steering trim, and adjustments should be saved (like you did) in a transmitter's model memory.

The above is correct. The reason for the delay was explained in an earlier post about resumption of support here.

But all Futaba receiver linked to a given TX will respond if they are turned on. Just the way things work.
