My question is: Is it a good idea to run dual corona ds 238mg servos in my merv? They aren't very expensive and seem to have good reviews. I have had 3 stock traxxas servos (ok, technically 2. one was rebuilt), and I want to replace it with a metal geared one. I'm not very interested in the hitec models. The bluebirds look good except for the price, so will dual coronas be okay?
