The work horse of RC for the past 30 years or more the RS-540SH-6527 brushed motor is a great, no nonsense solution to power your car or boat. This is the perfect solution for backyard bashers, vintage enthusiasts or anybody who doesn't need masses of power. These motors are great for novice class races at club level and are used buy many clubs to introduce people to RC racing.
The best thing about these motors is they can be used in wet conditions with no effect, in fact "back in the day" racers would break them in by putting the motor in a glass of water and powering it up for a few minutes. So they are perfect for boats or crawlers that you want to cross rivers with. Just dry them out afterwards and give them a bit of oil and they'll be fine to go next time.
Must be used with a suitable brushed ESC (see related items below.)

As another reviewer helpfully stated these seem to come without a flat side to the shaft against which to secure the pinion grub screw. This is easily rectified with a Dremel, or possibly just an ordinary file though I've not tried that.
Otherwise this is a great place to get these motors. For the class I race (m chassis) rs540sh is mandatory at our club but they are quite hard to find for a sensible price. Most retailers only have 540J which is not the same thing.Classico motore Brushed Mabuchi mondato di serie sulle vecchie gig nikko equivale pi o meno ad un motore da 30 spire mancano i cavi di alimentazioni da saldare a parte per considerando il prezzo un buon compromesso ottimo rapporto qualit prezzo, consigliato.Great motors, work well in my 1/10 cars. Only 4 crowns because there is no flat spot on the shaft to seat the pinion set screw, and no mention in the description of such. Not a big deal as I have a dremel but I could see it being a issue for some.
