Quarter -scale Wheel 150mm

thingiverse

A landing wheel for RC aircraft can be made to simulate the Palmer Cord wheel/tyre as used on many Allied WW1 aircraft. This print is approximately one-fourth scale of the ubiquitous 700x70 wheel if fitted with a 19mm diameter tyre. Print two identical pieces and superglue them together back to back, using a 5mm drill or wire through the axle hole to centre the parts and rotate to align the spokes. Apply oil or grease on the wire to avoid it getting glued in. The original wheels were wire-spoked and had fabric covers for drag reduction. Make simulated wheel covers out of thin card with textured wing covering ironed on. Tyres are made from rubber cord, which can be obtained as neoprene or nitrile rubber. Neoprene is much lighter and stretchy but quite soft and easily damaged - probably okay on grass strips. With neoprene, cut the cord to a length so that it will have to be stretched a bit to go on the rim. Join the cut ends of the cord with superglue matching them carefully. Nitrile rubber has no stretch, so it must be cut to exact length and glued in position already fitted around the rim (much more tricky). This item is similar to the Vintage Wheel designed by diogolopes - which I freely acknowledge. You might want to take a look at that one before you decide which one to print. I decided I wanted a deeper rim to help retain the tyre, and I reduced the number of spokes to eight. My axle hole is 5mm diameter. This wheel design is totally fresh; not a remix.
