it took me a month and a half to build a mojo but my major mistakes were that I did not buy the removeable wing kit which would have made it an easier build and also I spent a month of the building time just covering the plane. I went a little crazy on my covering job and way over did it. it took me over 3 days to glue the wing in because I covered it first and didn't use the removeable wing kit. when building its easier to clamp the top of the fuselage to the wing kit center section then trying to get the covered unruly fully assembled parts together lined and square and clamped with emough pressure all around to get it to bond completly.
