Mars RB1806 2000KV Brushless Motor


Availability: In stock

Looking for a powerful motor to go with your Mars gearbox? Look no further! The Mars RB1806 2000KV brushless motor is specifically intended to sit between the Mars 25:1 planetary gearbox and the Mars AM32 35A motor controller! Featuring a 3mm internal shaft, high strength N48H magnets and go-faster-orange finish, this pocket-rocket is more powerful, more efficient, smaller and lighter than its brushed Mars RB180 and RB370 counterparts.

Of course, the RB1806 is a solid choice for any small-scale project requiring a motor of this size, it just so happens to be plug-and-play with our other Mars hardware!

Please note that if you order a Mars motor and gearbox as separate items, they will arrive as separate parts in the box in need of assembly (pinion gear and M2 screws are provided with the gearbox) – if it’s a preassembled Mars motor+gearbox combo you’d like, we have you covered!

A little intimidated by brushless tech, or perhaps on a tight budget? Our Mars RB180 and RB370 brushed motors are perfectly viable alternatives to the RB1806! And don’t forget, the Mars AM32 35A ESC was quite literally made to run this motor and will give you the most out-of-the-box performance possible!
