I haven't flown mine yet but the quality seems good.
I replaced the 5/32" main gear wires with 3/16" Robarts.
I have an Enya 90 4 stroke in mine.
A friend at my club has a Saito 100 in his. He flew his maiden on his last week and it is a wonderful flying airplane. The tail has a tendency to bounce alot on a grass runway but aside from that it really didn't show any bad tendency.
PS: I have heard that the Tower 75 2 stroke is a good engine for this airplane as well.
I should mention I did lay in some fiberglass inside the firewall and forward 2 inches or so of the fuselage (I have heard the firewall mounting can be a bit weak and that Enya is a heavy engine)
