When 2.4 came out a few years back I was and still am flying my 1/3 cub on 72 meg, I frequently had glitches, not bad ones but still they were concerning. I and some other folks attributed them to all the flying wires on the float rigging. I was told about the 2.4 eliminating any engine or metel to metal interference, so I bought a futaba 2.4 and never a glitch again. The only problem Ive ever had is when I put the ignition to close to a throttle servo on a 50cc yak and it raised hell with the servo. We used to put chokes on long servo leads back in the 80's to avoid interference, but honestly I dont even worry about it anymore
