HI on FUTABA 72mhz for 20 yearschl 54 never a radio issue-the more people that go to 2.4 the less traffic on the frequency boardonly a few people on the board at my fieldTHERE IS LESS CHANCE THAN IN THE PAST THAT 72 IS GOING TO HAVE INTERFERENCE UNDER THESE CONDITIONS ( it is being used less )WE DO USE THE PIN METHOD TO PROTECT A GIVEN CHANNELS USE -if it ain't broke don't fix it ! ! ! ! ENJOY REGARDS TONY
