This is my beautiful 3" Japalura. I create some 3D parts to make it comfortable to put everything together. I choose this heavy frame because I need a strong and durable copter and it is that kind. I think the maximum lipo will be a 850mA 4s everything more makes it to slow. I like the back end and how I plug the connectors. The anenna will be changed to a better one but until here...I love it.
