Default Help with chossing a good servo

Can someone tell me which good servos to get from either HiTec Or Airtronics. I need a speedy racing servo ranging from $50-$200.

Thankx for your advice

Get the Ko high speed, the fastest servo you can afford and its only 100.00 the other 100.00 should be spent elsewhere.

Try asking your LHS to order it, you can tryfinding it on-line. There are plenty of RC online shops, incuding the sponsers to this site.

for the ko stuff look here:

http://rctech.net/forum/showthread.p...113#post715113

go to the first post, and follow the link.

it is for an analog servo (2113), but the same site sells the digital(2123).

likely the best servos out there right now.

0.06sec/9.5kg*cm - can't be beaten.

Gotta KO 2123 myself - extremely fast, precise and realiable. Can only reccomend it.

I agree with Cole Trickle. The PDS2123 is the best servo made, imo.

I got one at X-mas and it;s the best servo I've tried so far. I close second comes the PDS-2143. Still really fast, digital, and a little easier to use in gas cars since there is no FET wire. Both are awesome servos and you can't go wrong with any of the Ko Servos.

Thumbs up

the only other series of servos that come close to those specs are the 94X57's from sanwa/airtronics. and the new 94758 digital from them.

the interesting thing here is that this is acheived with only 6.0 volts.

well, digital versus analog, refers to the type of control applied to the servo motor. the digital servo "checks" itself much more frequently, and will have stonger holding power given the same specs. both can work well.

a plastic gear servo is just that. the internal gears that transfer the movement from the servo motor to the final output gear can be plastic, metal, or usually a combination. in my opinion a metal gear is quite superior regardless of what type of servo it is. it can be more precise, will grip the servo horn better, and the screw through the center will not likely strip out.

So wat ur tryin to say is that anolog's with steral gears are decent but a digital servo is much better, reliable, quicker and more pricy am i right?

It depends if you have that fet servo wire. I have one. The Ko digital one is only 15.00 bucks more. If you don't have the fet servo wire, just go with the analog one.

yes, that is a fairly accurate way to sum it up. a good analog servo can perform very well. you won't likely notice a difference until you are a very experienced racer.

the analog servos can post the same specs as a digital when it comes to speed and torque. it's more a positioning quality difference, than a raw power difference.

check out this link. it's a great reference.
