As I understand it that comment is directed mostly at the fly guys. Some of which use fairly small packs. It's a wicked servo, it does need current. If you are talking 1/10 scale electric I personally would be more concerned about the BEC. Just like any other high performance servo. Nitro be sure you have an adequate receiver pack. Whatever that is, I don't know.

I have 2 on 1/10 electric off roads, love them. Using lipos, with a Novak GTB and a SpeedPassion GT. So far so good.

People that race specs may well disagree, but in car the thing seems wicked fast. I have other servos with better specs, but these things seem faster to me. And it's just cool to have a totally brushless ride.
