Parts don't fit nicely together, there is a lot of sanding, and there are very vague with the instructions

It's a crappy design, too. Sticking the wings on the side and butting the sheeting against the fuselage is just plain dumb. The wings should have been built one piece and the fuselage clamshelled on top and bottom of them. Don't make a mistake (easy to do) in installing the aileron torque rods or you'll be cutting and reinstalling them. As for shaping the engine cowl - good luck. Hope you don't run out of wood! The tail doesn't fit the wing trailing edge well, either, and the vertical fins are hard to align properly. The attachment doesn't seem too strong, but I guess they hold up in flight. Covering this beast after assembly is an absolute nightmare!
