good cheap servo for my B4 ?
 

im lookin to spend like 30ish dollars hopefully

hitec 645mg

I use a Bluebird servo from hobbyking in my b4 its .08 sec. and puts out like 100 oz.trq.So far its lasted 8-9 full race days with practice, couldn't be happier.

you can get a digital servo for $30 from tower hobbies.

i run this one in my sc10, working great so far!

spend a bit more and get the Savox 1257 directly from them (savox) on sale for $47 :)
Awesome servo, I have it in my xxx. super fast.

I had a blubird before that and it worked well too for cheap. I think it was the 621mg or 631mg, cant remember.

Those are the specs on the 621mg. I got one that has 2 full race seasons on it in a SCT. good servo for the money.

I also use, and like, this servo. Sometimes,once in a while, it has some centering issues, but a quick reset fixes it.
