Put gear tyres on the rims. Insert one nut into the printed chassis and use the other nut on
the wheel axle as a counter-nut. Adjust the tightening of the bolt and the counternut so that
the wheel turns freely. Tie the centre of the chassis legs together with an office rubber band.
Tie the center of the chassis legs together with an office rubber band. Use the remaining
1mm wire to shape the rear chassis to your taste. Secure the rear wheel against sliding out
with a small washer and cover with glue or crimp the small brass servo bushing with pliers.
Weave the entire rear wire into the rudder and bend towards the rear. Check the functionality
of the landing gear assembly carefully.
