Orscheln Products manufactures Felsted™ Electronic Vernier (EV2), also known as Vernier Control for Electronic Engines. Orscheln Products has addressed many customers’ needs ahead of time with this product by incorporating some very unique features. The EV2 is easy to operate, and we have designed it to be easy to operate even with gloves on. The large size of the knob (2-1/4” diameter) makes it both easily identifiable and provides continuous engine speed regulation from idle to wide open throttle in seven full turns. We have also thought ahead to help prevent accidental over revving. To prevent this, the EV2 cannot be pulled to the wide open throttle position – it must be turned. Lastly, the knob comes with a quick shut-down feature simply by pushing in the knob. For more information about the Felsted™ Electronic Vernier (EV2), please click here to read more!
