Hi, I am completely new to electrics and, honestly, I am getting pretty frustrated. After flying the heck out of my Sport Cub (1S batteries), I purchased a Timber 1.5 and UMX Waco. The Waco uses the 280mA's. I purchased a Prophet Sport Plus charger and a 2S adapter. The battery connects easily to the banana plug adapter, but there is not a matching plug for the Balance Adapter. Can anyone steer me in the right direction? I want to get some flights on these before I build some Mini Scouts. Thank you!
