I am building the Bismarck. I have reached stage 57 #4. Testing the kites and motors. In a previous test, the jack staff lite, the anchor motors and the 1st 35 cm gun all operate as designed. All the lites in the the superstructure function properly. However the 2 motors for the radars don’t operate. Thinking it was a gearbox issue I disconnected 1 of the motors and tried it independently and still they don’t function. Is there a step I missed or am I doing some wrong. Please help
