Walkera Ladybird Frame

Our Walkera Ladybird crashed very often when we were learning to fly. Though the Ladybird is very robust, its frame gave way in the end.

So I designed a printed frame to replace the original one, and while I'm at it, I designed a double battery holder so you can carry two batteries for longer flight time.

Tip: Use a rubber band instead of the battery holder to save weight.
