Wow, don't know what you got but the one I got in the spring had most of the problems you menationed save that the 6 inch extensions on the wing servos would have been adequate. I fly on a grass field and use 3 inch rubber wheels and had no bounce problems. I did use a Sullivan tailwheel assembly so the tail sits higher than with the Sig stuff. My fuselage had not cut down for needle valve, I had to make it myself. The thin wood sliver that is supposed to go over the stab is a joke. I replaced it with half inch triangle stock because I was increasing the rudder by one inch in cord and one inch over the top and counterbalanced it. Biggest problem I had with mine was my own mistake, I used a Great Planes fueler. The soldier joint failed after maybe ten flights so it got bypassed. I uused Super Tigre 60, later a .75, and finally a .90. Flew great with all of em. You'll enjoy flying it.
