My second joystick models vacform. Highly recommended as it was really enjoyable to build. Lots of scratchbuilding needed - all struts, interior, every detail including the underwing radiators, fuel tank and the gun ring. Had to source some wheels form an old pfalz as the kit wheels were basic to say the least (and only one wheel supplied). Despite the HAlberstadt CL IV being described as the best ground attack plane of WW1 there don't appear to be any other kits! Also quite difficult to get information on the colour scheme. Eventually settled on red/brown as several sources mention it and there are photos of one coverted to civilian use in 1919 that appeared to still be in original camouflage. Will definately build nore joystick kits as they look good when they are finished.
