I may have missed them but there are three things I did not see.  First, a sanding block that is flat on one side and rounded on the other.  I think I got mine at Sears.  It uses 1/4 sheet of regular 8.5x11 sandpaper cut parallel to the short edge.  The round side is great for inside curves like the wing cutouts on the Uproar fuse.  In fact I think that's when I starting using mine.  Second, a 24x36 Fiskars (or equivalent) self-healing cutting mat - indispensible for cutting covering.  Third, a hobby sander similar to the T-bar.  It is used to sand round and V shape leading edges.  I have some good, some not so goood, and one bad experience with mine so you may want to talk with someone else but do look into one.
I built my Uproar in two weeks.  It goes together very fast and is so much fun.  After a month at the field there were 2 others.  Then 6 more guys went together to buy a group deal and within another month the field was full of them.
