40 meg is tempting, but I like the idea of turning on in the pits to fiddle with my ESC
I also like the piece of mind knowing I'm not going to have problems with outher drivers. We've seen it all before. A shout
"Who's on ......," as their car does something it was not meant to do. With 2.4, you can ignor them
However, if you have 40 meg, and you find the driver that turned on, you can poke thier eyes out with the arial from 3 feet away.
So there are advantages on both sides
