Electrical issue - please help!

[Foyzy]

Hi all,

I am experiencing a weird electrical problem with my Xray touring car, hoping someone out there can help.

I am running the Team Wave Eclipse motor which is supposed to light up blue / green / red. Whilst sometimes it works and the car runs fine, quite often the lights on the motor do not come on at all even though the motor does run. In these cases, as soon as I go full throttle, the car suddenly swerves to the left (like an extreme case of torque steer) making it completely undriveable. There is also a slight delay on the throttle, so when I floor it, there is a split second delay before the car responds.

Is this a motor issue or a speedo issue (I am running the Hobbywing Justock). I am thinking it is a motor issue as the lights aren't coming on, but then why would that cause the car to swerve off lot one side). When the motor does occasionally work properly the car runs perfectly, so it is not a question of chassis balancing etc.

Any help gratefully received. Thanks
