Thanks for the input I was considering the Futaba S9551 I will likely go that route as it keeps coming up. Im guessing it will feel as quick as the S9352HV does on my Cobra which I like. I was leaning toward the R10 pro because of the field programmer had an LCD screen. I use mostly MACs and drudging out the Windows laptop to the track to tweak is a pain. Im used to the RX8 two button thing and have a hotwire but always wanted a better option without having to use the PC. That was worth the extra money. Im assuming from what I can tell it is a very nice ESC, pretty reliable, and small too which is a plus.
