Searching ebay for a kit and stumbled on these for sale in Taiwan with free shipping to Australia :banana-dance: . Chassis are extended Womps, motors are original Mabuchi 16's I've had hanging around since the '60's but gave ém a cleanup and they rev pretty hard. Wheels and rear tyres are Pattos and used the kit tyres on the front and the kit wheels were shaved down to make the inserts.
