servo centering problem?

[Snelo]

Just build my Mardave v12 VRX this weekend.

All is good apart from the servo will not centre. I've uploaded a video to show the problem below.

The Servo is a Hitec.

After reading round; is the problem due to having the wrong servo saver? As i think hitec servos have 24t and therefore require the red servo saver.

If this is the case what size is the servo saver? Small, Medium or Large?

Is there anything else that could be causing the problem?

Thanks

1. Put the car on a car stand and try it. Carpet maybe causing drag.
2. Which Hitec servo is it?
3. Which make SS have you fitted?
4. Which radio do you have? It may have a secondary steering centre sub trim in a menu.
5. Hitec are 24t on the spline so you need a SS to suit. A 25t one will be to big. Colour doesn't matter just has to be 24t.
6. Hitec are not the best at being consistent when returning to centre

You have the wrong colour serve saver on your servo....as you said in your post you need the red kimborough servo saver for hi-tec servos

Could also be the servo it self....some hi-etc servos are known not to centre to well :-/

I would also check the steering hubs are not binding and check the steering cups are not tight on the ball studs on both the steering arms and servo save......if you can change them to schumacher ball grippas (ball studs and cups)

I have seen this with both of my mardave cars. The problem both times was the bullstuds and cups. They should be loose enough to drop when you lay them horizontal, most just stay in the position you stand them in.

Also you tend to find the servo will centre when the car is moving as is rightly pointed out grip dont help.

Mardave do a a good adjustable set, in black.

I have seen pictures of the Mardave 'Red' steering cups with the tops cut off to free them up but can't find a picture at the moment

Is it a new servo saver? I was having problems with mine. The spirng must have lost its tension over time and would not take the weight of the servo movement.
