Servos are rated to 144oz 0.18s/60 if that reliable i don't know but they seem to do fine for me i may upgrade the steering servo in the future though as even for my level i can tell this is where i will want my next performance hike, anyone around intermediate level will probably need something a bit quicker and then you may as well go FRE kit. The radio is a skyion and can be seen [link=http://www.cenracing.com/skyion.html]here[/link] i ahve to be honest and say all i do is turn it on and go, im not abig fan of wheel transmitters and will go stick 2.4ghz as soon as ripmax supply the futaba i want later this week.. hopefully
