Dissecting the Russian Granat 4 Drone: A Component Overview

• 0:00:06 Introduction: The video examines various components from a Russian Granat 4 drone.

• 0:00:12 Power and Interconnection: A power supply and interconnection box features connectors for servos, the flight computer (possibly "Automatic Control System" or ACS), payload, and engine ignition.

• 0:00:48 Servo System: The drone utilizes multiple Hitech servos, including a smaller HS-225MG, two HS-7955TG (titanium gear) models, and an HS-5665MH (possibly "High Voltage super torque").

• 0:01:59 Flight Computer: The flight computer has two pressure inputs (Pitot and Static) for measuring altitude and airspeed and is constructed with multiple PCBs.

• 0:02:33 Communication System: A communication assembly includes an antenna, likely operating at 868 MHz, possibly using a commercial board.

• 0:03:00 GPS System: The drone incorporates a GPS antenna and module.

• 0:03:24 Propeller: A well-preserved carbon fiber propeller with a length of 57 centimeters is shown.

• 0:03:51 Engine: The drone's engine, manufactured by MVVS (a Czech Republic company), is in good condition and includes a starter-generator.

• 0:04:19 Engine Details: Features good compression, and uses two Hall sensors. One is in conjunction with a temperature sensor connected to the motor's cylinder.

• 0:04:45 Throttle Control: The engine has a manual air intake adjustment and a servo motor for throttle control, mechanically linked to the carburetor.

• 0:05:10 Ignition: Includes an Ignition Control Unit, with a High Voltage Output and a second Hall Sensor.

• 0:05:26 Engine Mounting: The engine is mounted to the drone using large spacers and silent blocks.

• 0:05:35 Power Conversion: The starter-generator is connected to a module that likely functions as a converter, with a three-wire connection and a power supply. This module is also connected to a second module.
