Eswube's excellent Dreamliners came with the Rolls-Royce engines (Trent-1000), so I thought about doing one of them with the alternative motorization: the General Electric GEnx.
It was a fairly easy task as the nacelle is almost identycal to the RR one, differing mainly in the intake and exhaust, plus details on the engine itself and the supporting pylons.
