I agree with most of your posts about the durability of Hitec servos. I think mine lasted because they were used for years in light weight cars like the rs4's. I got the R40's a few months ago and have only run in a few races with them. I keep a real close eye on the servos though and have been looking around at the Futaba S9550's. So far the 645's have held up although I have had issues with the micro servos in my micro RS4. The other reason I havn't bought new servos is that one R40 is for me and the other for my son. They are set up pretty much the same, and we race in different classes. So I figure there is always a back up car.

I just think that for A3, the Hitec servos could be a good option. He doesn't race so he won't lose a race because is car wouldn't steer correctly. It really depends on his budget though. I agree that better servos are a good investment. I know when I started, I really needed to get the cheaper servos. Now I have the money (but not time enough to race) to upgrade. Hitec also has a good warranty program. You just gotta wait till they send it back.

I have not used the new futaba digital servo's as i'm on a good thing with the ko-propo digital ones, but i have heard nothing but good things about them so far, and they are cheaper then the ko ones as far as i know.

i dont know if weight is the problem with the hitec servo's, i have a small hitec in my yokomo 1/12th scale and have no end of problems with centering issues especially down the straight aways when the last thing you want to be doing is correcting at 12th scale with a 10 turn motor... almost impossible your hit the wall before you even think about where your going :/ maybe some are good and some are bad... like a lotery, if your one of the lucky 20% that get a good one... keep it lol

The servo saver I have is the one that came with the car. I have not upgraded to a better one since I didn't know this would cause such problems. What kind or brand servo saver should I buy? Any recommendations? I will try this first and if this doesn't solve the centering problem I will look into a new servo. Thanks alot guys for all your responses and keep em' coming....=P

Were you able to check the servo saver? You could just replace the worn one with another stock unit. Kimbro (sp?) is probably your best bet for a combo servo horn/servo saver. Make sure that the servo saver is causing the problem first though. In a pinch, you could put CA in your old servo saver to lock it up. Just don't hit anything! :lol:

I ran JR 590's in a XXXS and never.. I mean never ran a servo saver,just a horn.I never had any problems with the servo(I did keep a spare in the tool box..:lol: )I did hit "things", I race and it happens..:lol:

Well whatever the problem was I think I have fixed it. I was parking lot bashing with my friends the other day and the car got away from me and hit a curb at full throttle. It flew up in the air and I saw parts flying off everywhere. When I checked for damage the whole left side was gone, that piece of plastic crap they call a "tuned pipe" was shattered and the chassis was warped. The engine seemed fine though, just a small piece had chipped off the heat sink. So i went on line and decided since I have to fix all of these things anyway why not upgrade at the same time? So I bought a new chassis (wanted the super chassis but a little more than i wanted to pay), all the parts for the front suspension with titanium turnbuckle set, carbon graphite front, back and mid deck. I also invested in a RD logic tuned pipe (chrome). My RS4 looks really great now and after I rebuilt everything I just adjusted the camber, toe and caster. Now it centers like it's supposed to. I think what it was that caused the not centering problem was the POS plastic linkages that comes with the car. Thanks all for your input.

Taking everything apart, inspecting and then reassembling the car will allow you to fix almost any problem. If you don't take it apart you can't see many of the parts. I used to try to avoid doing this and spent many frustrating hours trying to figure out my problem. If I only had spent 20 minutes taking it apart, I could have found the problem quickly.

Dissasemble, inspect, replace bent, broken, or damages parts and reassemble and 99% of the time, your problem will be solved.

Thanks for posting that you figured out the problem.

Well there you go, I would have put money on it being the Hitec servo. I have had one good one in 5. Futaba all the way.
