The removable landing gear

On the slopes that I practice, with thick but uneven grass, the terrain is more favorable to a "sliding" than "rolling" landing... But on a nice retro glider like this, it would be a shame not to have landing gear. From a "neo-retro" perspective, I could have gone the extra mile to install a retractable landing gear. But it's heavy, and it also weighs much on the budget... So I decided to make a train that I would describe as more "removable" than "retractable"...;)
