I'm in the final stages of assembly on my Ultimate and have enjoyed most of it. The only real issues I have had with the kit have been the sheeting provided for the trailing edge has been very brittle breaking easily. I should have changed it out for something a little more substantial.
The fuse sides are heavy dense wood on my kit but should hold up forever. I have decided to go with a ST 51 for power. I need to get out and finish the rudder hinging and then get to sanding it all. I haven't decided on a covering scheme yet . Life keeps getting in the way...
