MS-GnK PLUS: Alternative powertrain for MS-GnK using Roboman Imbellers OR Kuryaka Daybreak+ Flywheels

UPDATES:

01/06/2026

• Updated tolerances on Upper Front, Rear, and Top Rail, alongside more space for the ESC.

• Thicker Cage Mount Front, means barrel is less likely to wobble around and come loose

• Cage Roller added to Cage Mount Front, preventing darts entering the flywheels too early

• Renamed to MS-GnK+ to better reflect different wheels using Plus Motors

11/08/2025

• Barrel retention method changed to a bayonet type fit, which is much friendlier on printing tolerances compared to a thread

• Flywheel cages edited with a smoother exit from the flywheels, found darts were getting caught on the cage and folding

• Cage Mount Rear edited to allow more space for the esc, but also removed the need of having the esc mount

19/07/2025

• Added locating nubs to Upper Front and NMS Upper Front components, eliminating the need of filament pins to keep aligned 

12/07/2025

• Daybreak update! Added alternative cage that is compatible with Daybreak+ and PlusBeans flywheels

• Imbeller cage improved with better cable routing, less bending required for the heatshrink next to the motor mount

• Cage mounts changed to fit both flywheel cages

• Upper Front changed to fit both flywheel cages

• .step file updated to reflect changes

23/05/2025

• Updated to match latest V1.1

• Upper Front changed to accomodate toolless access to Flywheel Cage.

• Cage Mount REAR changed with slot for easier assembly.

This is iMS-GnK, essentialy just MS-GnK using a single stage flywheel cage with Roboman Imbellers and Kelly Industries Plus Motors!

This is fully interchangeable with stock MS-GnK parts, I use a connector on the ESC to easily swap out the flywheel cages. In theroy no changes are needed to the firmware, but bear in mind that the solenoid on delay may need to be longer since the flywheels are further away from the dart, and you may need to use different ESC settings. 

FPS is now dependent on your flywheel choice. There is a 39mm spacing between the Plus motors. Compatible flywheels include Roboman Imbellers, Daybreak+ wheels, Plusbeans wheels, and other wheels compatible with the JPEG blaster (though please compare the wheels to the .step file to double check measurements)

Upper front shroud for NMS-GnK has also been included in case you wanted to create an iNMS-GnK!

No further hardware is required apart from the bolts included in the Plus Motors.
