Our latest X-Factory shipment is due to clear customs on Tuesday coming (23rd), there is another batch of plastic chassis in there, so they should be readily available again in good time for the 28th.
In the meantime have you tried contacting any of the dealers on our website (
www.xfactoryrc.co.uk) many of them carry good stock of X6 spares and several of them have had plastic chassis from us just recently (since after new year)
