This is the infamous buzz bomb that terrorized London. When reading about this one is amazed at the number of these that were launched during the war. It was a good thing that the launched sites were so vulnerable to bombing and the Germans could not remote launch from mobile sites. For your info TAKOM makes a V-2 that is 1/35 scale and would be a companion to this model.
These flying bombs were so slow that British planes could catch them and get a wingtip over them and flip them off course to crash into the sea or miss their targets. Shooting caused a large explosion and several planes suffered damage and were lost.
