Pieces did not fit well together. Of course there is to be some trimming, sanding and clamping etc., that's expected, but the huge problem was attaching the wings to the fuselage. There was sizable gap between the fuselage and wings which I had to use a two part epoxy to secure the two together;both for construction/adhesion and filler.Had to position plane perfectly using props and weights to make the right wing pitch and wait overnight to see if it all worked. It did, then I had to sand and file to get it all smooth. Was tempted to discard the whole project but it turned out pretty decent.
