Adapting an arbitrary airframe for airborne early warning is difficult. The aircraft needs endurance, the ability to lift heavy radar and mission equipment, room for operators, and very short takeoff-and-landing performance when it serves at sea. Meeting all of those requirements in one fixed-wing design creates unusually severe compromises. A helicopter partly sidesteps the problem because it already offers vertical flight, a broad cabin, and useful load-carrying capacity, although that does not remove every AEW limitation.

Why airborne-early-warning aircraft are hard to design
An AEW aircraft must combine endurance, a heavy sensor and crew load, internal working space, and short-deck performance, making the mission unusually demanding.
