The parts are already so excellent and pre-made that all I had to do was put an inner tube in the nosewheel tire and slide a few bolts into place and tighten a few nuts to the pre-determined torque.. total piece of cake.

Below, I insert the inner tube.

Slide in a bolt or two so the wheels stay in the trucks.

Tighten a nut or two to hold it all together. This part of the job might as well be a remote-controlled toy airplane, really. Just a really BIG one is all.
