HM-4#3B-Z-41: Walkera RX2406B Brushless Receiver for Walkera 4#3A, 4#3B, CB100 & Heli-Max Novus FP

Tech note: This receiver must be installed with the correct orientation, it must be in a stand-up orientation on the helicopter, not laying down like the RX2436 receiver on the CB100 helicopter. Failure to install the receiver in the correct orientation will definitely cause the gyro to malfunction. Also the tail signal connector on this receiver must be connected with an ESC that has 3 plugs instead of 2, one of the plugs has a single white wire. goto
