Sry to say but DO335 never saw action, even the few prototypes were not flown (like i.e. the FW190D11-13 prototypes) in combat missions.
The DO335 had an special feature to protect the pilot in case of emergency bail out, the aft prop and the top vertikal fin were ejected by explosive bolts. That ensured that the pilot fell away from the plane in one piece and not many small red ones.
Didnt know if the front gear was weak, but landing was a bit difficult due to the lower vertikal fin, the pilot had to approach and touch down in a very low angle, if i remember right nose not higher than 10-15 degree above horizon.
