Works well in in the Radiomaster Boxer

When I purchased my Boxer, RR was out of stock on the 6200mah lipo, and I wanted something better than the 18650 holder, so i went with this pack. Works great, fits the Boxer well, great runtime. i can fly a 3-4 hour session without powering off, and still have plenty of life. Charges fine in the Boxer as well. Happy with the purhase.
