Undercarriage main wheels with separate cast hubs, a tail wheel leg made from special very tough PX resin, plus a separate cast tail wheel, all of which is designed to fit Airfix’s Mosquito B Mk.XVI. As these Airfix kits feature a rather serious flaw – the undercarriage legs are very close to each other resulting in a very narrow wheel tyre, this set cannot be used with any other Mosquito kits (Tamiya, Hasegawa).
