QuickDraw 180 Motors by Ray

Finally, 180 motors that meet the demands of modern brushed flywheels! Thanks to Ray, we are now stocking what I consider the most performant brushed motors for full sized wheels on the market. These motors are designed for 3S operation, though they have also successfully operated on 4S in our limited initial testing. Coupled with our latest Manshees, you can easily achieve well over 200 fps with a wide range of darts.

QuickDraws are dynamically balanced at the factory for smooth operation. As far as we know, these are the only flywheel motors on the market with dynamically balanced armatures.

Technical Notes:

The most obvious visual difference between these motors and others is the dual shaft configuration. This serves a few purposes. Most importantly, it allows the user to install flywheels without applying pressure to the motor can or cage, which can otherwise damage bearings, break cages, or in extreme cases, distort the motor can itself, leading to shaft misalignment and motor failure. When installing wheels, ensure that the rear shaft of the motor is held firmly against a hard surface.
This extended rear shaft can also be used with small magnetic encoders for a closed loop control scheme. We do not currently offer those, but they are available from sources including Pololu, Aliexpress, and Amazon. If you are capable of implementing such a control scheme, I'd expect that you generally know what you're looking for.
Ensure sufficient clearance for the extended length of these motors compared to 130s - not all designs for 130s will be capable of using these. Most flycore based designs can run these without issue.
A close-fitting cage is important to maximize rigidity and minimize vibrations. In testing, a snug press fit on the motor can dramatically reduced noise from vibrations and improved velocity spread. Metal cages should require less interference to achieve the same rigidity.
