Since I've had 3 Do's so far, what worked best for the belly pan(keeping it on permanently)for me was using a soldering iron to remove the covering,only need to remove enough to get epoxy on the wood under the belly pan.Use belly pan and pen to draw a line,remove covering 1/16 to 1/32 in. inside the line so bare wood will not show.If any there are gaps,fill them with epoxy or any white glue/caulk.Use thin cardboard(cereal box) as spacer material at the ends when glueing.(wing on fuse) I had no problems with the wheels supplied,you should store the plane propped up off the wheels to keep them round.No type of glue seems to hold for long if the covering is not removed.
