I use the same radio for both 2.4 and 72. Other then not using the pin board I don't see 2.4 as an upgrade but I have been changing over slowly to 2.4 over time. I have only forgot to pull the antenna once and that was long before 2.4. Being complacent or forgetful isn't a problem with the radio system, it's just an operator malfunction, sort of like sticking your hand through the spinning prop to make an adjustment. Sh#t happens.
