i just ordered a savox one. i heard those were good. ill find out this weekend haha

[crawlerwon]

i have savox also which one did you get? i find that they are okay but they are louder, weaker (even if rated the same), and larger than the hitec ones i own. well except the hs7980

[Charlie1670]

it was a 40 dollar one. rated at 222 torque at 7.4 volts. figured its good enough.

its probably alot better than stock but if its going on a rock crawler you may end up with a stronger servo.

Savox SW-1210SG/ 277.7 oz @ 6V (claimed) Strong enough to push rocks bigger than my rig out of position w/ my wheels. I don't see the need for more torque than that besides ego.

i guess it all depends on the type of crawling you do and the difficulty of the lines you pick. i have a rock course consisting of about 20 tons of boulders in my back yard and the average boulder thats the size of my 2.2 truck weighs 20 to 30 lbs and 277.7oz @ 6v = 17.3lbs per inch then you take away from this for linkage and tires. i had a savox 222 oz servo in my wraith when i got it used and i swapped it out instantly for the savox sa1230 which claims to have 500oz @ 6v. cause 222 oz just was not enough to make it through my course without alot of reversing. im not saying that 500 oz is what you need, but i also have a few 2.2 pro bergs and i can tell you 1st hand that the 611oz that my hitec 7980 produces can get me out of situations that my 7950 which has 496oz cannot. that being said in certain situations even my 7980 stalls when the tires are wedged good enough
