The board was easy to instal with the tools that came with my Chrima. There is a electronic part that did not come with the board but was very easy to remove from the old board and reattach, I did a link and set dates etc, etc. It came online and I was test flying in short order.
Great machine.

Although, after much trial and error and research, I did finally get the system dialed in correctly, and my Chroma now flies excellent. It was extremely difficult to get the flight board, receiver and controller to bind together. Information is not readily available. Each step of the process had to be repeated several times before the changes took effect. It took some patience but the final result is well worth it. My Chroma now flies better than ever before. I would recommend purchasing this product.
