Hi everyone. Being brand new to this hobby, I recently purchased a Tamiya Plasma Edge kit. I built it fine and it kind of works, but, there are two big problems.

Firstly, the acceleration is really jerky. I pull the trigger on the radio, and it stutters several times whilst getting to full speed. Worse still the throttle sometimes gets jammed on full, sending the car smashing into the curb!

Secondly, when I pull hard on the throttle, the steering servo veers to the left, making control difficult.

If anyone has any ideas, I would love to hear from you.

Cheers,
Felix
