Have you found something yet? I have an F550 for sale: F550 with Aerial Media Pros heavy lift upgrade. You get the original DJI motors, one spare Aerial Media Pros motor, all Graupner props on motors and 3 spare Graupner props, original DJI props and several spares of varying sizes, photo gimbal: SR Pro Micro Go Pro Gimbal, NAZA M with GPS, lights on front arms.
I had this built by Atlanta Hobby. Frame has about 10 hours on it and Aerial Media Pro motors have less than 2 hours on them.
No batteries/transmitter included.
