This just popped in my head while racing last night in multiple classes. Right now to switch my lynx3d from one vehicle to another, I change the profile and then change the freq on the spectra unit to match whats in the vehicle i need to run. It would be neat if each profile in the transmitter had a frequency associated with it and when the profile changed, the spectra unit would automatically switch to the defined frequency. I know this cant be done with the equipment now, but maybe if hitec makes a new model they could work it in
