The HobbyStar 540 4-pole brushless, sensored crawler motor is an ultra-smooth powerplant for upgrading your crawler to brushless power.  A beautifully machined T6 billet-aluminum housing contains a 4-pole, 12-slot high-torque rotor spinning on High-RPM ABEC5 oversized bearings for a powerful, reliable motor choice for your 1/10 scale vehicle. 

NOTE: Max LiPo cells listed are a guideline for what voltage can be safely run on this motor, but it is still critical to monitor temps and adjust gearing accordingly to keep motor temps under 170F.  Any motor can overheat to the point of failure even when running less than the maximum rated voltage if it is over-geared.  Must adhere to ESC voltage/KV limits as well.

Features:

• Engineered for smooth operation
• 4-pole 12-slot high-torque design
• CNC machined 6061 T6 billet aluminum can
• High-purity copper windings maximize efficiency
• High-RPM ABEC5 oversized bearings
• Precision balanced rotor for smooth operation and maximum RPM
• Super-thin (0.2mm) stator laminations 
• Removable/replaceable rotor

HobbyStar 5-slot brushed crawler motors feature an innovative "skewed stator" design that delivers a smooth powerband for excellent control when driving on steep and rocky terrain.  Dual-ball bearings provide peak performance and reliability, while adjustable motor timing allows you to rotate the motor can to dial in for your application. Easy to maintain waterproof design, just dry them out and give them some oil after a wet or muddy run and they'll be ready for another round. If you are looking for a powerful, reliable, economical and versatile powerplant for your crawler look no further!

Features:

• 5-slot armature for ultra-smooth operation
• Adjustable timing
• Waterproof
• Available in a variety of turns
• Pre-soldered leads with bullet plugs
• Dual ball-bearings
• Rebuildable
