Rc is a luxary for me with time , between work and my boys ice hockey its my last freedom of choice to fly . I alwasy finding myself ready to fly with no batterys .
Then one day asked the same question , an rcu member suggested a simple $26 purchase called a Lil "Trickler " I now own three , its the best little investmenet I ever bought , batterys on tricle charge , always worked great , never a lost plane due to battery failure , always ready to fly , and best part its a plug and play set up , no sodering ect out of the box ease
