Do a search but just about any of the Mods that have been done to the Tm or Stiks would apply here. It seem that the Cub kinda got lost in the rush to buy the TM. But most of us that have one like them great flyer but the wings have to be made stonger. And DON'T fly with out the wing struts or SNAP!Also the mounts for the wing struts should be turned 90 degrees on the wing and fusalage. And yes the wings won't hold up with the sticky tape to hold them together. I took mine and cut the wing tips off and turned the wings around so I now have square wing tips.
