Simple landing gear for RC model aircraft

First design on a robust landing gear for my Multiplex Twinstar II.

Main design aim: To absorb the forces and momentum into a large body area. Most other landing gears have a very small mounting surface. So they break off at hard landings.

UPDATED! Apologies, the wheel STL file had to be reduced to upload correctly. (Meshlab. From 4.6MB to 421kB.)
