The Airfix Churchill has beaten more than a few modellers.  It has faults.   The gun barrel is too fine and the turret is too small, and lacks the distinctive widening at the base.  The tracks though are very good for their age and the hull builds up to look satisfyingly massive.  Yet the hull has its difficulties, and has bad memories for many modellers.  We feel that these may be overcome to a large extent if the assembly order indicated in the Airfix instructions is changed.  

The Hull: If the inner hull box is built first and left to harden many later problems of alignment are solved.  This is especially important  if any resin conversion parts are being used, but is a real help if building the hull straight.

The Bogies:   All those bogies!  So many Airfix Churchills end up with roadwheels that do not quite align. This picture shows the problem.  The builder has taken a degree of care, though not enough, to align the outer roadwheels.  The problem will come when the tracks go on.  Careful examination of the bogie units against the tracks will show that if you assemble the bogies with the wheels pushed in on their locating lugs, they will be too close together for the tracks to sit correctly.

The outer flange of the wheels should sit outside the inner thick body of the tracks.  It is worth assembling  the bogies on the sprues as shown on the left.  The picture on the right shows the difficulty of the kit: getting the wheels true on the bogies.
