The FA-223 Drache (Dragon) first flew in Aug. 1940.   In Oct. 1940  Karl Bode  flew a prototype breaking records for helicopter speed,  climb rate and ceiling.   Based  on the results of test flights an  initial  order  was  placed  by the military for 30 helicopters with materials ordered  for an additional 70.   Three prototypes were eventually pro- duced.  Initial production was to be in five versions:  Anti submarine, observation/recon, rescue, transport, and as a trainer.  After further testing it was decided to produce the FA-223  in one adaptable version instead of the  five as originally planned.   As with many German WW II  military projects, production was limited due to government indecision and the Allied bombing of supplies and man- ufacturing facilities.  The Germans did use it for flying in supplies, and also use it for medical evacuations.  Would be a slow easy to hit target, and extreamely lucky to get to a target without really good air cover.
