Schumacher kc build issues

[Darlophil]

I've just finished building my cougar kc but I've got a couple of issues that I'm struggling with so I'm hoping someone will be able to help point me in the right direction / tell me what I've done wrong.

1) steering / servo - I've mounted the servo as per the instructions but when ive connected the electronics the steering is reversed. I.e. when I turn the wheel left on the transmitter the wheels go right & Visa versa.

2) drive / power - I can get drive to the back wheels in a straight line but as soon as I turn the steering I lose drive to the rear wheels.

Are the two issues related and is it going to a relatively simple fix?

Thanks
Phil
