I have one with the old color scheme and I love it. My advice (free if you can believe it):

1. Go over the covering real good with an iron, especially on the wings. Stuck-down like. I ran a strip of 3/8" red vinyl auto trim along the leading edges because there was not much covering overlap, and a gap in some places
2. Put loctite or nylock nuts on the capscrews that hold in the landing gear angles. Mine were on the way out after about 20 flights.
3. Fiberglass the top and bottom corners of the engine box as well as the sides. The roof and floor of the box both vibrated loose after 40 flights. My 3W-150 ran crappy (i.e ROUGH) for quite awhile before I fixed it - that didn't help.
4. The engine box is JUST tall enough to accomodate the engine mount. You have to carve out the balsa gussets inside the engine box to allow a washer to fit down flat and you have to trim the inside washer so it will fit beside the box roof/floor. I would start with a fender washer and trim it. I found that the trimmed standard washer has too small an area and just crushed the ply after repeated tightenings.
5. I trimmed off the vertical fin mount from the fuselage to help stringing the cables and servo wires (I installed plug n'play connectors for the stabs) before mounting the fin. It's easy to separate cleanly from the fuse, makes installation of cardboard tubes, etc easier, and is easy to replace before mounting the fin.

I have some pics on my web site (www.kdrader.ca) in the gallery section if you want to see what I did.

Fantastic airplane!
