Great deal! Can you send me the details on your suspension? Was that an upgrade? Many thanks!

At one point Groen Brothers supplied larger steel tubes for the upper landing gear tube. I never liked the original hard rubber doughnut
suspension design so I added the coil shocks to the new larger tubes. This was just an experiment ... that may or may not have worked once the gyro was at completed weight. These shocks aren't anything special, just common power sport shocks... I think they were rated at around 800 lbs each. I thought just about anything would provide smoother taxiing and landing over the original design. I realized that after testing I might have to change to stiffer or softer shocks, or possibly go back to the originals which I still have.
