Mardave Cobra

[Fast Eddie]

I have just aquired an old Cobra and am getting it ready to race. Keeping it brushed and would be interested to hear any advice on set ups, motors etc and does any one else have one lying about for my lad.
Also I have never skimmed my motors and wondered what this really does and what kit I would need.

Here is a before picture, will take some as I go along.....
