little problem
 

Hi,i know this probably should be in the electrical section but as its only happend in this car,im just wondering if anyone else has had it or any help,when the servo makes a buzzing noise it makes the speedo full throttle light flicker,when i turn the servo as i would when racing with car jumps forward,it makes the car very hard to drive
thanks
Mark

It sounds like your getting feedback from your servo to your speedo.

Obvious stuff first.

Check wiring for breaks and or bare wires.
If your speedo has a capacitor, you may need to check it. Try swapping it for a new one.
This is all assuming the problem has just appeared.

You could also try resetting the speedo.

If not, it's time to swap servo then swap speedo to try and find the faulty component.

thanks Adam,its just started,i will give them all a try

all iv done is moved the speedo wire as far away from the servo and its fine:thumbsup:

Maybe servo and esc tabs are touching each other :woot: inside the receiver?
