We wanted our Urupema to have a landing gear with suspension (as we often fly on pretty rough alpine slopes). Georg designed it, and Richie built the mould for the cover. We spent a lot of time sourcing the right size of the various bits and pieces. The sides are made of 5mm glass fiber. A friend was able to mill the glass fiber sides on the basis of our drawing, and another friend helped us thread and cut aluminium parts to size. Today I assembled my landing gear. Fits perfectly.
