trust me this guy was a good builder, i've seen him build at least 20 different planes in the past year i've known him and all have been fantastic machines, so much though that i've bought 2 off him myself! theres an aermacchi he made which is drop dead gorgeous! has to be seen to be believed, haven't flown yet though as i'm waiting for the day to go flying! Its built to prop hang and knife edge though im pretty sure, definatly prop hang as i've had it prop hanging whilst i was holding onto the wing and it was stable as a tank!
