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.)The connection bar is re-heated and bent over a beer bottle. Choose a good beer for best results. Assemble with two 2.5M machine screw and nuts. Use "Locktite". The nuts tend to come loose.
