Not everything needs to be modern imo.. I'm going to use a 10 year old servo.. I could have used my 27mhz radio gear I suppose, but i fancied something cool.. 40mhz would still be viable.. maybe even more so as everyone else will be on 2.4 so you'll be guaranteed a free frequency. I think the bits that matter are the batteries, motor and esc.
