My set up for non magnet Fly Classics for a wood track is:
:: Replace the back axle and front stubs with with slot it axles ( usually 48mm)
:: Stock bushes for the rear axle.
:: Keep the original pinion and use a 19mm Slot it SIGS1936 Lightweight spur gear (19mm diameter, 36t.)
:: Keep the original wheels and front tyres. NSR Classic ultragrips on the back. Glued and trued all round with the fronts ground down to get maximum guide depth.
:: Pod glued to chassis.
:: Motor glued in.
:: Chassis perimeter shaved to allow body rock.
:: Any points of chassis contact with the interior base dremmelled off (where possible) to promote body rock.
:: Chassis to body screw holes widened and thinner screws used to promote body rock.
:: Don't use the rear chassis screw.
:: Try and avoid added weight - most of the models don't need it.
