RE: Z P-38 wood or glass
I know the guy that has the P-38 SJN posted pics of. It´s powered by DA-50´s with MenzS 20x12 3-blade props. The mufflers are homemade by the owner.
It flies very well with these engines, although the props are too big, so they lug the engines down quite a bit when doing vertical manouvers. I think he said that they did about 5500rpm on the ground.
