Savox Servo

[brown4s]

Guys,

Couple of questions regarding these servo's:

- whats the difference between the high voltage and normal servo's ?

- Settled on a 1258 for my durango dex210 but if I wanted to get a better savox servo e.g cost was no issue which is the one to get that could be also used for future use in 4wd as well ? The 2270 through to 2274 seem to be the most expensive but are they best suited to 1/10 buggies ?
