There is a setup which might give an idea of what I am trying to achieve on this Blog at:
The only problem is I don't have enough experience to be able to identify what all the parts are called.
It look from this like I'm after a relatively small RC (toy) car and then I'll need to take the front axle off and just have one wheel attached to the front servo?
If I understand the next step I think I would also need to remove the rear wheels and attach my sidecar wheels?
Having just seen the Tonka Ricochet Trickster (Buzsaw) I was wondering whether to simply cut a hole on the base of the sidecar and pop one of these in?
