Wanted to see which servo those who are running a single servo on an E-Revo 2.0 use? I was going to go with the Traxxas Red Hi-Torque 400 part #2255 but wanted to see others choices.

There are lots of options that don't involve giving more money to Traxxas. The Protek 170TBL and 370TBL series servos are excellent. The Holmes SHV800 servo requires a power lead, but is an exceptional choice as well.

Thank you, I will definitely look into these.

Not surprisingly Traxxas servo gets poor reviews on amain. Look at hitec and reefs like reefs 500.
