So.... don't try these. Here's what i found, 1 - They weighed a little bit more than i anticipated. the extra weight will surely drain battery faster. 2- The only place to attach to is the landing gear. Well when the landing gear retracts, the cubes will come in contact with the props. What will work is using a rotary tool to file down the back edges on the cube adapter to a point where it will slide on. It has to be filed down enough to get past the antenna wires and landing gear.I think I've found a solution that will work on the cubes with RS installed. Check out the clamp on Amazon. Attaching this clip to the land gear should work just fine. Comments are welcome.
