Do you need to test your aircraft's arming against bombers? My bomber is a good solution, this aircraft is a mixture of Avro Lancaster and FV-200 Condor (but the Lancaster genes were clearly dominant). Closer to the point, on my bomber there is a defensive armament that performs its function. To activate it, you need to press group 7 (activate turrets) and turn off group 8 (turn gyro to stabilize and turn off control planes.) Then switch the camera to the turret and with the mouse, shoot the enemies. The turrets of this bomber are armed with the 4th 7.7 machine guns, and 2 20 MM cannons from the British BIAS, and 18 bombs of 250 pounds, remember! To drop bombs, you first need to open the bombard! Enjoy!
