Sadak 2T (110kg , 388kg fully loaded)
Sadak 4T (175kg , 731kg fully loaded)
Sadak 4T is carried under the belly of Akinci, as it can’t carry that load on wings.
Akinci has around 950kg payload capacity to carry externally. I doubt if it can manage 2 x Sadak 2T on wings as well.
As with different engines, Akinci has different payload capacities. But even with the 2 x PT6 engines giving 2 x 850HP power, it has a maximum of 1500kg payload capacity, 400kg of it being for internal. It has also be remembered that the wing structure can manage lower weight handling than it’s belly.
