Check it out and perhaps, plan for your options and spares when you purchase your DRB.... ^-^ We will have spares and options together with the arrival of DRB in our shop. However, we expect to have complete list of parts within a month. Hobby Haven always support our clients for all requirements of Yokomo products. Please contact us to reserve your DRB. Cheers.
