I was just looking through the Tamiya site at race results and saw a pic of him on the stand holding a Helios. It is really hard to say with these guys since their support sponsers seem to change frequently. If he is deffinitely on the KO now it is a really good radio, not that the M11 is not, it pretty much comes down to how it feels in your hand. I personally did not like the feel of the M8/11.
JRXS Type R, I have four of them!! ;) ( Yes, I still have them!!)
