Most aviation buffs are familiar with the Mistel composite aircraft used by Germany at the end of WWII. These consisted of Bf 109s or Fw 190s mounted above unmanned Ju 88s, to which a large warhead was fitted. The pilot in the fighter aimed the Ju 88, then detached while the bomber flew on autopilot to (hopefully) impact the target.
The Mistel composites’ low speed made them vulnerable to interception, so German designers proposed three variants based upon jet aircraft. Mistel 4 utilized Me 262s for both the upper and lower components. The Mistel 5 design used the He 162 as the piloted aircraft, with an Arado E 377 purpose-built payload which was also jet propelled using two BMW 003 engines. The Mistel 6 was to utilize an Ar 234 C/E upper component, and an unpowered E 377 lower.
Dragon kits the Mistel 5, which contains an He 162, a powered E 377, and a take-off trolley. They also make several versions of the Ar 234, which include the Ar 234 C/E with four jets. Modeling a Mistel 6 is possible by combining the two kits.
