I am interested in your product with some modifications. The height of the front drive wheel would need to be at least 265mm above the ground. The width of the entire chassis would need to be 400mm. The request is for a product with chassis, rubber tracks (as shown in your photos) and motors. This is for prototype vehicles and if the product is accepted then production schedules would be negotiated at a later date., I'm looking for a motorized chassis similar to this with some modifications. Total chassis/ track width 400mm. The centerline of the front drive wheels would need to be at least 265mm above the ground. My request is for the chassis with rubber track as shown in your pictures, and drive motors. What would be the price with these modifications? This initial request is for prototype use. If the product is accepted then production schedule can be negotiated at a later date.
