Product Description

Scorpion HK-4525 V2 / HKIII-4035 Motor Shaft Kit, 6mm shaft (30mm)


Factory replacement shafts for all the HK-4525 & HKII-4525 series Scorpion Helicopter Motors


This is the new version shaft made from a new, much stronger SKH51 Steel alloy that will hold up to the most extreme flying styles. If you are looking to get the hardest and strongest shaft available, this is the one. This material is much more expensive than the earlier material used, and is why these shafts are significantly more pricey.

 Please measure your helicopter to be sure that 35mm of 6mm pinion shaft area is correct for you. 


Included in the Package:

  • - Scorpion HK4525 Motor Shaft (for 6mm pinion) OEM x1
  • - Washer x 1
  • - C-Clip x 2
  • - Set Screw x 2

Note: the shafts in the Scorpion motors are a slight press fit into the aluminum front housing. The shafts will not just slide out when the setscrews are removed. They need to be pressed out in a bearing press, or in a drill press, with the front housing of the motor supported in a block of wood to prevent warping the front housing.
