I have just got a spektrum dx2e and sr201 receiver for my HPI Firsestorm Flux. I have followed the instructions to correctly bind the transmitter and receiver, however, after I remove the bind plug and try to use it normally, the steering servo moves by itself. Also when I try to steer, sometimes it will move forward.

Is there anything I can do to fix this, or do I need to ask for a replacement?

Does the throttle work at all?

When you say the steering moves by itself, you mean it sort of vibrates quickly back and forth close to center?

You confirmed you have the esc and servo in the right plug?
