Digital Servo Help...
Just getting back into 1/10th after about 16years and a lot seems to have changed
 Just got a B44 which came with an associated DS1313 servo. Remainder of the electrics are as follows: Ansmann 2.4ghz radio gear Mtroniks SM800 speedo (circa 1993 - pretty good in it's day) Corally 12x3 (I think) motor also 1993 vintage. Seems to have full set of capacitors still The car runs ok but got some servo related questions 1 The servo seems to make a noise as if a load is being applied to the steering when it's stationary and the car is on the floor - is that normal? 2 When I turn the servo quickly from lock to lock the speedo comes alive and the buggy moves forward a couple of feet - could this be due to my ancient speedo? Brushless is not really an option for a while so need to make do as best I can...

Digital servos may hum even at neutral, usually with a little fine tuning of the trims and the linkages you can get rid of it. Make sure you set the end points on the radio correctly so the servo does not hum loudly at full lock, it could damage the servo.
The speedo lurching sounds like interference from the servo coming through the receiver. It may be related to the speedo, or it may be related to the servo. The Ansmann radio is made by Sanwa (I think) so should be decent quality.

Thanks for the reply - Need to do some tweaking of the linkages as they aren't even at the moment and I seem to have a bit of toe in too.
I've turned the EPA right down to stop any buzzing at full lock so hopefully that'll be ok. Any suggestions on how to deal with the interference? I guess I could try my old 27mhz kit and see if it stil does it then....
