Yes, the vibration level is so high that will destroy your plane. I had the experience with an Abbra and the ZDZ 40. The ailerons fluttered really bad and we were lucky to land the plane. Installed the hyde mount and the problem was solved. The reduction of vibration and noise was just hard to believe. Here is a picture. The weight was 5 ounces over the limit but we were using 3 blade carbon prop that was too heavy. I think a wood prop is the solution in that particular case. I don't know what is the difference in weight between the ZDZ40 and the DA50. I guess that the DA 50 is a little heavier.
