servo question.
 

i am in a need for a replacement servo. my savox 1251 isn't that good because it draws lot of amp.

i can't quite afford a futaba servo.. i have to look at cheaper servo :(

anyone run :-

ABSIMA ACS1612SG servo
Alturn ADS967HTG

Does they (arm) 'lock' when its powered off?

and do i really need <0.10 sec servo for 2wd buggy on tight track?

The arm should not lock on any servo when off,
Does it need to be low profile? I have a 1251 in a TC which I suppose is what it is designed for but I have Alturns in everything else including outdoor TC, and don't think I'll ever change back, at £20 each you can keep spares if you think you need to
