Just as a note not all 2.4 systems use model match. Ifly airtronics and on the FHSS-1 it does not use any model match I can take off and fly with the wrong model selected. I have been carefull thus far to avoid it at the field but it has bitten me once when I went to program a new plane into the TX. I do not see any huge areas of gain from 2.4 to 72. I fly on both and perfer my 2.4 radios not due to the frequency but due to the ease of atjustment with the computers in them.
