Hello! I recently bought a dynam extra 330.. and in one of the drop down menues there was an option for an addition battery. I selected the option of the blue lipo 1300 mah battery, which was available at the time. I recieved the battery, but it does not have the correct connecter to connect it to my airplane. What do i need in order to connect this battery to the plane.. The connector for the airplane is a small two pin type...and the new battery has larger circular leads. Thanks for you help
