Just put together my first clod with NN chassis, super rooster and lathe motors and the servos and motors are twitching like their smoking crack? The servo's are Hitec 645mg's and the motors are eagle racing 55T lathe. Can anybody advise on what the problem and fix might be.

Thanks...

What radio/rx are you running, and did you install caps on the motors?

If your antenna wire is close to your ESC, that may cause it. More info would help.

caps=capacitors
Some use them, some don't. Make sure ALL the batts are at full voltage.

I've never had to use capacitors to help eliminate a glitch. It's always been how the wires are run, and where things are placed in relation to each other.

so you are running two 645's through a rc18t reciever? I bet that is your problem. Try a different receiver or bypass the power around the receiver. The small tracks on the 18T receiver won't let full amperage through.

Good catch JRH!

I really should read more of the words.
