Status: offline 		Hello

At the moment i need a good servo for racing. First of all what is actually better for racing, analog or digital? Obviously i dont wanna spend too much on a servo but if its a good quality servo that works well and will last please give me its name and perhaps somewhere online that i can buy it, whether it be analog or digital. It must have a lot of torque obviously and preferably a lot of speed aswell, im probaly willing to pay from 80$ to 140$+ (ive seen people pay a little for there servos and then they break and they end up wishing they bought the best). But preferably 80$ :P, can anyone offer any help?

Thanks
Alden

:S

Status: offline 		if it only does that when the car is just sitting on the ground and not moving, then you don't have a centering issue. A lot of people think they have "centering issues" when they really dont. I bet your servo returns to center if the car is moving...

Status: offline 		If you reread my post, you'll notice that I said just because it doesn't return to center while the car is not moving AND ON THE GROUND then it doesnt necessarily mean you have a centering issue. However, if you're car does that when there is no restriction on the wheels, then you might have a problem with your servo, or maybe one of your linkages is binding or something. Just trying to maybe save you from buying a new servo if you don't really need one. Non-digital/non-coreless servos won't center as well as digital/coreless servos if the car is not rolling. The coreless servos have much more torque near center...
