I've seen one with a zdz40 and it looks clean. I'm sure it has enough power to Hover. Its too bad the plane isn't worth squat. Be prepared for some really nasty stalls, the plane flops around like a wounded bat totally out of control untill you get the airspeed up. Trust me, Your going to freek out the first time it happens.
I have over 200 flights on one with a Saito 180

You may want to create a new leading edge with the proper shape. (Basically less blunt) I've been told thats where the problem is, and reshaping the leading edge will help.
I think the airplane is down right dangerous, and it's being discontinued. Go figure.....
