Exclamation Which servo to get?

I race asphalt tracks with my Cyclone and i also do offroad with my b4...

just wondering whats the best bang for the buck servo thats fast and tough? I currently run a JR Z90 in my cyclone, a 645mg in my Tc3, and a 645mg in my B4. Ive never really felt they held me back but i notice that some of the faster guys use much more expensive servos. I always felt that once i had a "fast enough" servo, it all came down to how good of a driver i was to beat even the fast guys at the races i attend. Is this wrong or partially wrong?

Lately ive been thinking of upgrading servos. Some friends that i race with that are also very fast (much faster around the track than i am) have been suggesting that i get faster servos after watching me race lately. So here i am, knowing very little about servos, asking you guys what you suggest. Incase its any help, i run a MX3 FM radio. Thanks.

if you can still get one, i've got a futaba 9550 and its quick enough for me. Small size too.

A quicker servo helps put the car where you want it on the track... quicker And that is pretty useful for blocking someone...

wait a second that KO mentioned earlier is rated at 7.2v? Is that accurate?

Any suggestions for airtronics or hitecs? I thank all of you for your input, just want to get the full spectrum of suggestions. So far its all JR, KO, or Futaba lol.

You could go with the AE 1015. It's plenty fast and has way more than enough torque as well.

Just be careful when going to faster servo's. That KO is probably too fast. I had a JR servo that was at 0.08sec and it was way to quick for anything but throttle on my 1/8th buggy.

I would vote for the Futaba 9551 though. It's a lo profile servo, meaning it's not quite as tall leaving more room on the chassis for the other electronics, depending on the layout of the cars.

Chris.. you should go Ko. Robert will take care of you. He's the owner of Ko Propo and he's based out in Gardena, so service is real fast. check here.. they'll have a servo for whatever u need.

If you go back a few pages in Paul Lemiux forum, he does a pretty good explanation on what he likes for a steering servo, and he seems to do pretty good in touring car, LOL. I think he prefered the 9550 as well, but I could be wrong.

looks like KO and Futaba are the top picks then eh?

alright chris, of those KOs on that list from the link you put which do you suggest since i know you're an avid (and fast) TC racer that knows the OC Circuit tracks as well...

Futaba needs no suggestion, looks like its 9551/9550/9452 or bust haha.

at which point do you guys say "thats too fast for a steering servo"? (.10 seems to be the happy medium as far as transit time it looks like)
