HobbyStar 540 Pro V3 Competition Brushless Sensored Motor
The HobbyStar 540 V3 series motors are the next generation of a championship-winning powerplant that continues to push the boundaries.
Along with looking amazing, the all-new can and stator design maximizes cooling efficiency, to raise the bar yet again. The V3 Spec-winds have shed an incredible 20g of weight, making it a full 40g lighter than the original, V1 design at only 140g.
Underneath the beautiful can lies an all-new sensor board, stronger magnets in the rotor, lightened stators, and a beefed-up endplate. Gold-plated solder tabs and titanium-nitride coated aluminum bolts keep it all together while keeping things light.
Available in SPEC and MOD versions, as well as an all-new MOD-ET version which comes with a high-torque rotor and stator optimized for drag-racing.
Features:
- Re-designed motor can for more efficient cooling
- Increased strength neodymium rotor-magnets
- New stator design is lighter and more efficient
- Titanium-nitride coated aluminum can screws
- Gold-plated solder tabs
- Weighs 20g less than V2 motors
- Available "ET" version for drag-racing with high-torque rotor & ceramic bearings
