The CWL-309Helpme-K-JMS-ST35 mounting plate is NOT compatible with Sanwa JLF mount cases such as MadCatz TE or Qanba Q4RAF. It is recommended that you add the .187 to 5-pin Conversion Harness to your order if are installing into a model that instead uses a 5-pin connector rather than .187" terminals. You can save $1.25 when you option bundle with this product. Partial assembly is required; install joystick lever through body, push actuator into bottom of lever stem, and push up against the internal spring to connect the e-clip. Use needle nose-pliers to fasten the e-clip to the bottom of the joystick lever, pushing it into the lever's bottom groove.
Crown has released several Korean style models within the 300 numbered series, such as the 303-N, 307-N, and now the 309Helpme-K. In this iteration, Crown carefully reviewed feedback from diehard Tekken players - specifically Helpme, and eschewed select characteristics from earlier models to deliver what many would consider a happy medium for gameplay.
Meeting in the Middle
The 303-N main characteristic is longer travel distance, while the 307's larger actuator shortened dead zones. The 309Helpme-K-JMS-ST35 is Crown's closest attempt to mimic the popular Myoungshin Fanta Joystick, narrowing the throw distance and a smaller, durable 16.5mm polyoxymethylene plastic actuator.
The Difference in Silicone
The ST variant uses a white silicone rubber tension system with a shore A rating of 35. This is indeed lighter than the 55 shore A rating in the 307 series. Tests conducted at Hibal, however, show that the silicone is slightly thicker in the 309. Executing command input are easier, while returning to neutral is a bit tougher from the reduced tension.
Still, the benefits of the rubber tension is a faster return to neutral, which is perfect for 3D based games such as Tekken in which wavedashing and consistent movement is required. The CWL-309HelpmeK-JMS-ST35 continues to share the same characteristics as other Fanta joysticks, with smooth, cornerless control for QCB, QCF (quarter-circle back/forward) HCB, HBC (half-circle back/forward) and full 360 motions.
Korean Gersung GSM-V1623A3 Microswitches
The CWL-309Helpme-K-KMS-ST35 currently uses a Gersung GSM-V1623A3 .187" Long Straight Hinge Lever Microswitch. Like the 303 and 307 models, each microswitch can be removed from the joystick and replaced by another. This opens up potential for customizing the switch sensitivity and performance. The body of the CWL-309FJ-JMS-ST encloses the microswitches, offering a tighter form factor than the 303-FK.
The bottom construction of the CWL-309-HelpmeK-ST35 joystick lever matches that of the 303-N though colored black. The microswitches are positioned closer to the actuator than the 307, and are not embedded into the housing as the 307. See specs below for measurements.
