How's the receiver size compared to the HRS? In todays world of small space electronics for touring car a small receiver is a must. I couldn't get away with much larger a receiver.

I'm assuming there is no difference in receivers for the M8's or KO's or Futaba? Hopefully they'll drop in price from the $80.00 they're at....god knows I'll need atleast three if I decide to go with the spectrum. RCtech and Ebay will be flooded soon with receiver sales.
