The RT is designed around the reliable 3 volt 1/3N lithium battery, which gives it it's unique shape and size. It is also now made with the new, efficient and rock-solid 'XR' circuit (Extra Reliable).   The RT Plus was developed to be a primary leg or tail mount for larger shortwings and longwings (18 oz birds and up).
