This makes a significant improvement in performance!!! I do not understand why going from a 540 KVA to a 580 KVA motor would make this much difference, but it does. I use it in a FMS 1450 mm P-51 with the sip tie prop mode. It accelerates, climbs, and fly's faster. I find I am able to throttle back more and get about the same battery life.
I installed this motor on an HSD A6M Zero. It works fantastic. I´m using a 12/6 prop. Very quiet and lots of power.
Upgrade for FMS P-51B
Purchased motor for upgrade to FMS P-51B . The first motor Motion sent me was defective (missing a magnet). They made it right and sent another. Second one works perfectly. That, along with the propeller pitch mod, has given the P-51B the speed that was missing with the original setup.
No Motor Mount
This brushless 4240 580 kv was designed as a replacement motor for the FMS 1400 mm series of planes. But unless you are going to use it one of those planes, it has serious deficiencies. It comes with no motor mount. Mine came with a bolt on prop adapter, and appears to have been intended for use in the FMS 1400 mm Zero. I had other plans for the motor. There is a problem with the prop adapter. The bottom half inch or so of the shaft has a hexagonal shape--apparently intended to fit the back of the Zero propeller. It doesn't fit any other propeller that I know of. And since Motion RC doesn't seem to offer a complete replacement propeller assembly for the Zero, I'm sort of out of luck. Bottom line--unless you intend to use this motor as a replacement in your FMS 1400 mm Zero--don't buy it.
