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.
P51B Snoot's Upgrade
The upgrade motor makes a difference. I have also done the zip-tie prop mod so the Snoot scoots right along. The new top speed is very noticeable and vertical climb is much improved. I would say with the zip-tie prop mod the motor is worth the money spent for better performance.
Like going from a Allison to a Merlin
I have two a P-51b & a P-51d one came with the 540 & one came with the 580, what a deference!
Motion RC is the best, parts on hand and very fast ship!!!
Flew like a dream
With the new motor and prop mod, the Dallas Darling P51 flew with such power and agility. I am very impressed with this simple upgrade. The Motion RC gang ALWAYS does great...thanks folks.
larger motor over stock
Ordered this motor, to replace the stock motor, which in all reality I blew due to overvoltage. Tried the stock motor on a 22.2v battery with a 70 amp ESC. Results were terrific for a little while. Ordered the 580 motor, which arrived in a very short time, suprising me. It was packed very securely with lots of bubble wrap. The motor went right into the Dallas Darling P51 with no modification. I haven't been able to fly yet due to weather, I am looking forward to doing that. Thanks Motion RC "gang" you did it again, super job.
Replacement for my P51 V8
This is a powerful motor that really brings my P51 Red Tail to life. I added a Gecko 85 Amp from motion and zip ties under in prop. I need very little power (1/2) throttle to get airborne. I love flying this plane with the setup and an Eagle Tree Gyro. Landings are a breeze with mid-flaps. The next thing is to replace the tires as they are very hard. Dave Brown tires should be ideal.
