Both toys offer similar capabilities, but Horizon Hobby provides excellent world wide support to their customers if the toy needs repair or replacement parts. For example, my Blade 350 QX complained that my DX-8 aileron trim was constantly drifting. I sent my DX-8 in for service. Horizon Hobby replaced both gimbals, a capacitor, and brought the transmitter back to factory specifications before sending it back to me. They are famous for this level of support. You may wish to consider the quality of their service and the availability of spare parts for their toys when you select a quadcopter for your father.
