Servo for 4WD
 

Now that I actually HAVE a 4WD car (ok, it's not built yet) and I HAVE bought my Brushless system (OK it's still in the box) I now need my Servo. I dont want to break the bank. What do you suggest for under £100 (well under £100 if possible).

KO 2123 is the best value KO. not digital. about £85 new i think, or about 30-35 second hand. Both mine are second hand and are bullet proof. 7.2v, metal gears, loads of torque and speed.

think the new blue birds are worth a look as a cheaper alternative new. But i don't think you will beat a second hand 2123.

I have the KO 2413 pds low profile servo, Seems very good to me.

im using a 9402 and is quick enough for racing as well as strong torque.

You better be racing it at marston.

What brushless did you go for???

As for servo's i think the blue bird servo's are ace metal geared strong and fast its all you could even need i think the exspensive KO's are silly money and thats in my opinion and i like all the exspensive new stuff like my ko tranny etc.

don't use anything bar ko2123 in all my car's. the mut's nuts

Cheers, According to the KO site, the PDS-2123FET is a 7.2V servo. Does it have a blue wire or just the three wire connection to the receiver? If it has the blue wire, do I need to put a choke in line with it?

Which bluebird (why could they not have chosen a less girly name) servo would people recommend? there seem to be loads. What does Stu have in the 501X?

What about low profile servo's? anything suitable in the price range?

ps - no Ash, im not racing at Marston, its not built yet and it might get dirty anyway. My new ESC is in my signature :)

yeah neil it has the wire the monk bought a cirrus servo digital off flee bay worked ace in his 4wd 21 quid ill get a link for ya;)

for £22 that's not bad! could do with a fraction more torque maybe for 4wd, but great for 2wd

they do 10kg model but a little slower so its a trade off speed or torque ive inspectwd the servo looks like a ko futaba copy very good quality;)

You have to race it means ill have everyone pileing into my gazebo.

As for the 7.2v servo's you shouldnt need a choke i dont use one in my 2wd never had a problem.

As for blue bird servo's this one is a good one i dont think its the same as mine ill have to check but the specs on this are good.

Thanks guys. The 2123 does look great doesnt it, all things to all men.

Andy, your little PDS-2413ICS, is that commonly used in 4WD or was it designed for TC's? - not saying its girly, cos i bet it looks so cool in the car (im digging a hole here....)

On the KO site it give torque in Oz only for the new servo's. The discontinued Servo's have the Torque in Oz and Kg but if you convert the figure in Oz into Kg you get a different answer so i guess the beam length used for the figure must be different? any ideas? im not a mech eng...

I tell a lie it is the one ive got just went and checked.

ALWAYS run a fet choke when running a 7.2v servo unless you want to fry it!

WOW that servo is nice that puts mine to shame it seems so measly and crappy :(

You could buy a JR servo of very similar spec but alot easier on the wallet ive had a JR servo and it was very good for the small sum of money i paid for it. And its still going stong.

would a HITEC HS 985 MG CORELESS ULTRA TORQUE, be any good for a buggy i just got one with a deal,

sorry for nicking in on your thread :wtf:

Not sure what my girly servo was made for neil, but it works good!! Wanted the lo profile one for when i run the Tamiya and it was that or the futaba s9550, not much in it.

Got one of them in my B4. Bit slow, but pretty tough.

Neil, bite the bullet and get a KO2123. Not cheap, but there are deals out there (especially from abroad) and you'll never look back!

:) I use this servo for the steering on my 1/8th truggy as it needs the torque, personally I don't like something that steers too quickly in off road. If you got it in a deal try it, if you doon't like you havn't really lost anything and you can still go and buy a K.O or something a little quicker but less torquey.......:)

I need a new servo, would the Airtronics 94360Z be any good? Its for an x-5.(http://www2.towerhobbies.com/cgi-bin...?&I=LXGGV8&P=0)
How affective would the heatsink be? Does the servo really get that hot?:confused:

I use a Hitec 5965MG personally.

I use the ko 2343 in both 2wd and 4wd.

Niel, have a look on wasacross.com and on the tech sheets you can see what all the top boys in the euros were using, if you haven't bought one already.

Hi,
I use a sanwa erg wrx in my predatorx10, mega fast, and good torque. A bit pricey in this country, but you can pick them up from foreign soils for around half what the rrp is in this country (around £110 :o ).
