Thanks Josh. I think where I was going is probably not the problem. I bought some Savox servos in the summer and that unless the servo horn was set at vertical they would not centre properly. I run my servo horns at about 1pm to 1:30pm to get 90 degrees with the servo saver link. My KO servos centre perfectly with the horn not at the vertical
But 1220 is only marginally off vertical so it doesn't sound likely I guess. Not sure
Sitting here without the car I can't remember but if the servo horn is pushed to the right ie in the direction of 1220, which way do the wheels turn and is that the direction you steering is sticking in? If so and you get nowhere with this, it might be worthwhile getting the servo horn exactly on vertical - probably means getting a servo horn set to find one which will fit exactly vertical. If you are stymied then if nothing else it would remove one of the variables.

Sure. I was going to ask you ,as we had this conversation a while back, is your servo horn dead vertical on the Savox?
Josh I am the old guy with short hair running the XRAY team. The old guy with long hair runs the other XRAY team. ;D

one thing that may cause this (may have been mentioned already). if the servo end-points are further than the arm can physically travel (due to steering links), then when the horn stops moving the spline on the servo will still continue and can cause the horn to skip teeth on the spline. Check that the end points are within the physical movement of the steering links and the end points on the transmitter dont go past the servo movement or horn movement  HTH |

HTH Josh, The above is a good point. The fact you set the steering up centred and the as you race the steering drifts very badly too one side must mean something is slipping. I would check the following: - Servo (easiest way is to swap for another one if you have one) - End points as Reubens has described or - Turnbuckle linking the servo saver to the servo is not jumping threads inside the ball cups. Sorry not going to be racing Sunday as I'm on Holiday ;D I'm sure Pete etc will sort it for you. |

Various servo makes can have very close spline patterns/diameters and a suitable horn will "seem" to fit but be slightly loose,this type can slip under load/impact just make sure your horn is a tight push fit onto the splines.also check that the horn screw is not "bottoming out" befor it tightens the horn fully home.

Ok, i suppose it could be the servo its self as its just plastic, will be upgrading to a new one at the end of the month but i won't be racing for another 3 weeks as i'm at the lake district.
