We sourced these packs specifically to provide a 2S option for F3K/DLG models or other small models. These work great in the Micro Max slope gilder and the Alien flying wing. 

Please note these servos should not be used in high draw applications, models with servos bigger than DLG size. These packs could possibly be used in a battery backup setup for F5J models.
