hey guys I just got a new 358 servo, 200 oz [email protected] and it wont even turn the wheels all the way on concrete, on carpet it is pathetic. I checked my battery pack to make sure it was good and its putting out 6.5 volts so i know thats not the problem. My steering linkages are all smooth and there isnt any binding. What is going on?

Does it do it in the air? If not check your EPA's. That does sound strange. Could be a bum servo, which is rare, but possible. But it has to be something in the connections electrically, a stripped wire, Weak connection from rx to bat pack or to servo etc.

It does not do it in the air, only when it has load on it. I have heard somewhere on here that you should put in your end points wth the car on the ground but i dont no. Its also just not a tourque issue because its really slow aswell. When i take it off the ground its really fast and turns all the way. I was really expecting more out of it then this cuz my 40 dollar servo is just as good.

LOL

somethings up man...Cuz I run the 359 on the front end of all my cars and it turns all of them, even my MT's lock to lock on carpet, grass, concrete, everything..And every now and then when im on my side on the track, ill cut the wheels to hop back on all 4. Doest work all the time, but alot of it.

what could it possibly be though

Im so bummed right now, its suppose to have 200 oz but if feels like it only has maybe 80.

Check your servo saver. Make sure its set properly. Are you sure there isnt any binding on the steering? Try another battery pack. Check all the connections on the rx. Make sure no wires are split. Hmm..I dunno.

What kinda buggy is it in? if its Pivot ball front than check your pivot balls to make sure they arent too tight. Free them up.

yea its pbs, ill try that, im gonna take off the turnbucks and make sure the balls are free, This is really making me mad, This servo is suppose to have way more power then this.

ok well i checked my pbs and its good, im telling you nothing is binding, I guess ill have to get another battery pack or try 4 alkalines and see what happens.

if anyone else wants to respond please do so

Thats a stumper man.Maybe im missing something, But it may just be a defective servo.

i would check the servo saver to make sure its not to loose. with that much holding power u should be able to really tighten down on the servo saver

also just a quick ? i cant see anyones avatars is it just my comp or are the mods playin around again?

i really think you could be right about the servo saver cuz it makes sense, i just tightened it now i gotta test it again.

k let us no if that was it

tighten the servo saver spring ive got one and it sucked till i tightened the spring. works great now!

nitroman88-RCU, I have the exact same servo. In the fact, I was doing the same exact thing for a while.

This is your problem:

When the buggy is in the air, the arms are fully extended to their max. You then set your end points. You put it on the ground and now the arms come back to level. All of a sudden the servo doesn't pull the wheels all the way. What's the deal? Well when you put the buggy on the ground and the arms come to their proper position, you are extending the amount of "throw" needed to turn the wheels fully. With the arms in the fully extended position, the distance between the steering knuckles and the ackerman is shorter than when the arms are fully laid out. If you look carefully at your wheels when you lift the buggy up and extend the arms, your toe out changes. All buggies do this, it's the nature of long travel needed in the suspension.

You would think Monster Trucks would be even worse, but then again how many of you hold your monster truck in the air while you set your end points? You gotta have three hands to do that. When we wrench on our buggies we throw them on the starter box. We also take the wheels off. Therefore, when put the steering servo horn back on and it's comes time to set the end points, why go through all the trouble to put the wheels back on? It's a common problem.

Moral of the Story, put your wheels on, put the buggy on the ground and THEN set your end points. (I did this and I got so much more steering!!!)

Before someone jumps on me... When you put the arms back in the fully extended position with the new end points and lock the steering, you will hear a buzz from the servo. You're over working it and constant abuse such as this *over time* will kill it. It could also cause a battery drain that might trigger your failsafe. That being said, when are the arms ever fully extended? when jumping. Wouldn't you agree that that it's pretty rare to turn the wheel and jump at the same time? ... OK OK you nit pickers... If you are correcting your attitude mid-air (turn wheel + accelerate), you may stress the servo a little if you lock it in one direction. You just need to be aware of it and not lock the steering when doing that adjustment. Also, if you're a good driver you should be able to approach the jump squarely and not have to worry about correcting a barrel-roll.

thanks for the reply Rob but should it be buzzing on the ground too. I know all my other servos did but I always thought it as because they didnt have enough tourque. Is this common?

the reason they buzz is because they are realy close to center but dont provide full torque once its 2degrees from center. it wears the batteries a little but is normal. once the car gets going theyll center.

So did it work nitroman?

My 358 doesn't buzz at all. I had some other servos do that. Maybe it's something with your setup. I'm running a 1100 mah 6v hump pack with the XS3 reciever.

I dont think it worked, mine buzzes and im running the exact same thing as you rob, 1100 mah with the JR xs3 reciever. I think tower screwed me over because it the servos little bag of hardware wasnt in the right spot and it looked like someone had opened it up. The servo itself looked brand new.

i would just send it back in original packaging and ask for a replacement. im not sure how tower deals with customer support.

sub trim can ajust the buzzing in the center

no buzzing in the center, im saying it buzzes when i turn it and then hold it there.

Rob: setting the end points on the ground only made things worse, the buzzing got louder as i increased epa.

Dude..its gonna buzz when your turning....thats cuz the gears are moving...when he is referring to buzzing he is referring to the buzzing when in the neutral position. This happens because the servo is trying to center itself.
