I don't have an issue with the stock one...it steers fine ? I may have pushed more voltage to it with my ESC.
The stock servo is a 7.2 volt servo...208oz at 7.2 volts. However, I think the stock ESC only has a 6 volt
BEC ?
Mine steers fine with the stock servo....it hasn't given up yet. Once it does or if it ever does...I'll look into a Savox....I have good luck with them.
