Doesn't anyone use expo in your radio? I've been running a Protek 170S at 7.4 volts in my etruggy and like it so much that I just upgraded my ebuggy to the same servo this weekend. I was running an AE 1015 in the buggy. But I run some expo on both so I get a little more precise control around center but heavier corrections go from my hand to the front wheels as fast as possible.
