Training landing gear

There is another type of landing gear already in this site but here is another option for you to choose, its made of 6mm CF tube and ping pong balls.

You just need to drill the balls and glue them with CA at the end of the tubes, the length of the tubes is 100cm.

To join them in the center just use two tie ups:

To attach them to the landing gear I use electric tape, it is more flexible than tie ups and will not pop off.
