Nimrod NT Blackbird 39K CNC Motor Short

The Nimrod NT Blackbird 39K CNC Motor Short is built with solid materials and is suitable for almost any setup.

Due to the high RPM it can also be used in short bursts of 0.5 Joule or less than 1 Joule builds. Pay close attention to the spring and the sector gear to prevent the piston or the sector gear from seizing and breaking.

The cooling port near the endbell provides impactful cooling without the risk of damaging the engine if internals fail. The CNC machined endbell also provides better cooling and a better fit and durability of the bearings in the motor. The Pinion Gear is made of strong material with MIM technology and with D-shaped fit it is easy to replace if needed. It also provides better power transfer than O-shaped Pinion Gears.

Nimrod recommends using this motor in the following setups:
32:1 / 18:1 / 16:1
Springs: M100 up to M140
