<p>The ZTW Beatles G2 Series is a new 32-bit brushless ESC for RC Airplane.</p><p><br></p><h4><b>Key Features:</b></h4><p><br></p><ul><li><p>Utilizes powerful next generation MOSFET with a low thermal signature, high peak current threshold and reliability. </p></li><li><p>Features high performance 32bit microprocessor as standard. Stronger computing ability and faster processing rates. </p></li><li><p>Super smooth start up and throttle throughout the power range</p></li><li><p>Higher driving efficiency and more energy-saving.</p></li><li><p>Adjustable SBEC output voltage, 5V/6V&nbsp;8A (14A Max)<b> (40A/50A/60A/80A/100A have SBEC adjustable)</b> 5.5V 4A (20A/30A)</p></li><li><p>Multiple protection protocols: start-up, over-heat, low-voltage cutoff, signal loss, phase loss etc.</p></li><li><p>Supports wide range of high RPM type motors commonly found in today's market.</p></li><li><p>Fully programmable via optional ZTW mobile app or ZTW LCD G2 programming card.</p></li></ul><p><br></p><h4><b>Programing Items:</b></h4><p><br></p><p><b>1. SMR Function</b>: <b>OFF</b>/ON</p><p>This function supports switching the motor rotation to decelerate when the airplane landing to the ground.</p><p>The factory default is OFF, the 1Pin signal wire is completely invalid at this time.</p><p>If you need to turn it on, using Phone App or transmitter to program it“ON”, plug the 3Pin signal wire into the throttle channel, and plug the 1Pin signal wire into any 2-stage switch channel of the receiver, then turn on the transmitter 2-stage switch. The SMR function is turned on now, you can change the forward and reverse directions of the motor by flipping the 2-stage switch of the transmitter.</p><p>Warning: This function can only be effective when the throttle is below 50%, and it is only allowed to be used</p><p>when the airplane is landing on the ground, otherwise it may cause the ESC to burn!</p><p><b>2. Brake Type</b>: <b>OFF</b>/Soft/Mid/Hard</p><p><b>3. Timing</b>: <b>Auto</b>/Low/Mid/High(5°/15°/25°)</p><p><b>4. Motor Rotation:</b> <b>CW</b>/CCW</p><p><b>5. SR function</b>: ON/<b>OFF</b></p><p>The synchronous rectification function makes ESC with higher driving efficiency and more energy-saving.</p><p><b>6. Battery cells:</b> <b>Auto</b>/2S/3S/4S/5S/6S</p><p>7. Low Voltage Cutoff Threshold: OFF/NIMH50%/NIMH60%/<b>3.0V</b>/3.2V/3.4V/3.6V</p><p>For example: using 3 lithium batteries and setting 3.0V as the low voltage cutoff value, then the low voltage protection threshold is: 3*3.0 = 9.0V</p><p>8. Low Voltage Cutoff Type: <b>Reduce Power</b>/Cut Off Power</p><p>Reduced power: When the voltage drops to the set low-voltage protection threshold, the ESC will reduce power to 70%.</p><p>Cut Off power: When the voltage drops to the set low-voltage protection threshold, the ESC will cut off the power immediately. 9.40A、50A、60A、80A、100A ESCs have adjustable SBEC 5V/6V, the default set is 5.0V.</p><p>10.Acceleration: <b>Normal</b>/Soft</p>
