ReadyEdi from multirotor4fly is now selling his own new miniquad batteries made especially to suit our racing needs. Those 4S 70C batteries are a blast! They come in 1500mah and 1300mah and are THE best batteries I have ever flown!
My friend ReadyEdi from Multirotor4fly came up with an awesome (!!!) upgrade for the already great Puffin 210. The upgrade allows to mount the battery in the frame, between the motors – at the center of gravity, instead of on top of the frame.
