First of all as i understand it has only been proposed and will be discussed further at the next meeting, im sure it will be announced before then to allow members to make their points.

From an EO and arena marshall point of view: This is something that we have looked at over the last few events. It is getting nearly impossible to run feathers in large fights (burgess hill we had 20 fighting at once) on 40Mhz, as it seems to just get drowned out. No matter what failsafes are fitted, it stray signals get through and can cause misfires and unctrolled movement. Its only a matter of time before we start to see these problems in the heavyweights.

Most robots are running 2.4Ghz now with only a few still on 40Mhz. 2.4Ghz setups can be bought for £70 upwards, you struggle to get a decent 40Mhz set for that, especially if you're looking at PCM.

FM radios have been banned in the USA due to similar reasons.
