securely holding the inner lock nut in place.
While holding the wheel pant aligned (the bottom of the wheel pant
should be parallel to the bottom edge of the landing gear bracket), use
the tip of your modeling knife to make a small pilot hole in the wheel
pant, using the predrilled hole in the landing gear bracket as a guide.
Install and tighten one M2 x 10mm flange-head wood screw to lock
the wheel pant into place and keep it from rotating.
IMPORTANT Don't overtighten the wood screw or you might strip
the plastic.
