is this servo enough for a stearing servo on a hyper st ? If not I was thinking the 0251 savox.its not that fast but should be strong enough.the jr is in it and it just seems a bit tough on it ,standing still it wont turn very well at all even with a full charge on a 6V pack.I know it will turn easyer when I break in the mill and its rolling.should I just go ahead and get the savox ? I do know that there is probably a better model of savox but my budget says thats what I can have....
