Instead, a fixed power (e.g. <strong>25mW<\/strong>) should be used. This is because in ELRS, Channel 5 is reserved for ARM\/DISARM switch and it corresponds to Stability\/Rescue vs 3D mode on the M1\/M2\/S1\/S2 helicopter. When the Channel 5 is disarmed (~1000uS), the Transmitter RF output power is reduced if Dynamic Power is enabled and this increases the chances of RF link loss if the model is used in DISARMed state. Using fixed power is crucial to avoid this problem.<br>In any case, we recommend you perform a range check with both stability mode on and off to ensure the radio range is sufficient in both cases.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Binding<\/h3>\n\n\n\n<p>It is highly recommended to remove the main and tail rotor blades from the helicopter to prevent any injury\/damage on accidental motor start up.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Power off your transmitter\/radio.<\/li>\n\n\n\n<li>Power-cycle the receiver 3 times.
