This motor is outstanding in my Timber. It's half the price of the stock motor, it's lighter, and according to my experience and ecalc.ch, it has more static thrust, more thrust at speed and yet yields more flight time. Flying for endurance with a 10x6, I cleared 16 minutes aloft with a 184g battery hauling two cameras, not bad! Another perk, the prop adapter is the right size to put on every prop I have (Master Airscrews, APCs) without having to drill or dremel. I suggest getting props of varying sizes for your intended needs (endurance, performance or a balance), though the 11x7 is maybe the best all-around for general flight.
