I think the zdz 60 isnt a good choice no matter what since the zdz 80 weighs about the same as the 60.

So i would go with the da50 if the weight of the plane approaches 18 pounds go with the zdz 80. In the case of this plane i beleive the plane will be closer to 17 pounds so the da 50 is the proper engine to go with. Of course these are my opinions.
