Funding 3 racers whom each race in multiple classes in the offroad, onroad, carpet, crawling, pulling, drift, drag racing scenes. Yes we could have spent less per radio but receivers don't get cheaper unless you go with a knockoff when you need as many as we do. Family teams is not a cheap adventure. So is you want to figure it out I guess I could have saved a little more going with a radio with less features and still going with the knockoff receivers but the bottom line is that the true cost of a tx/rx system is hidden in the cost of the receivers and not the radio. Maybe its different if you are only funding yourself with only a couple vehicles but that's not my situation. We do have a few FH5U receivers but frankly at my families skill level it does not make a difference. I would rather use the antennaless for the space savings and not having to worry about inspecting the antennas on all our rigs.

m17 x 3 @ $572 = $1716
knockoff 481 receivers x 60 (20 each person) @ $30 = $1800
Total = $3,516

mx-s x 3 @ $249 = $747
sanwa 481 receivers x 60 (20 each per person @ $99 = $5940
Total = $6,687
