Description

Want to get some longer flight time on your Tiny Trainer? This is a great pack to throw on with an upgraded battery tray (Insert battery tray file here)

These were also developed in partnership with Jim McCarthy, a very experienced F5J pilot. He was very happy with the results and gave us the go ahead to push these as our official F5J packs! 78 Grams. XT-60. Slightly smaller footprint then normal 850 mah pack.
