I built one for a friend last fall. Strong little sucker, but HEAVY. I think it came out 7.5 pounds. I covered it with Solartex, love that covering. It has a .40 size engine, but hasn't flown yet. Owner is going to try to stuff a .70 4 stroke in I think; not much room up there. I'll attach a picture.

One thread on here about them said it flies like "a bag of snakes". Not very encouraging, but sure is a nice looking plane.

PS, I remember now, it did take a huge chunk of lead in the nose to make it balance. That certainly added to the heavy weight, but couldn't do without it.
