On an approx. 3m sq. 22m lap length routed and fairly tight technical circuit how should I be gearing the car, just as a guide? Start nearer the 2:1 or 4:1 end of the scale. 

Currently the car has the standard Slot.it gear ratio of 11:28 (2.54:1).

I think that you will find that the "standard" ratio on Slot-it inlines is 9:28 (3.1 to 1)......that is the ratio on the car you pictured.

With the stock "orange" endbell motor, 9:28 works well with both the motor and most tracks........longer more flowing tracks may well benefit from a slightly lower numeric ratio, while tight twisty tracks may favour a higher numeric ratio.

It is important to keep the characteristics of the motor in mind when selecting ratios, as the motor will affect the ratio choice as much as the track.
