Ski for RC plane with tires

thingiverse

I found the ski for RC planes on Thingiverse which made me wanne have also some ski, but allowing to keep the tires on the plane. I basically kept the outlines, but added cutouts for the main tires and a small tail wheel on the ski to prevent scratching the ground. I used a small rubber ring (around 23x19mm) to give them some grip and durability. On the Ender 3, they can be printed on the diagonal on the build plate, however they need supports. I am using them successfully on a 3kg plane :), with 5mm axles. I used a small version of the ski which I remixed for replacing the tail wheel. To keep them aligned during flight and landing, I added some springs and cords on the front and aft. I added the ski also with separate axle mounts, so they can be adapted to different tire diameters. The design provided is tuned for 75mm tire diameter and 5mm axles.
