This is the Hobbywing XERUN Justock 3650SD G2 Sensored Brushless Motor. Considering the 3650 series has been around for a while and has proven it's usefulness, Hobbywing introduces the second generation, the G2.

The biggest and most notable advancement with the G2 is the updated aluminum can design. The first 3650 series used a iron case that looked bland and featured few ventilation holes. The G2 now uses an aluminum milled can that has been purpose refined with improved looks, improved ventilation and improved heat dissipation.

In-Depth Features:

  • Great Construction: The use of a heat-resistant magnet attached aluminum case and double insulated windings, Japanese high precision bearings, and rotor with a strong structure guarantees outstanding performance and super durability.
  • Cool Look & Good Heat-dissipation: The aluminum case (different from the Justock3650 G1’s iron case) with a unique design not only creates a cool look but helps to dissipate heat.
  • Linear & Smooth Control: The built-in Hall sensor non-adjustable end bell combined with a high precision and balanced rotor guarantees the user a smooth and linear power on demand.
  • Re-buildable Design: The end bell is easy to be removed for maintenance purposes and for the replacement of common wearing parts such as rotor and sensor module (Ex bearings).
