M39 and T160 are terrible guns right now and actually have been terrible for the last two years after the insane drag nerf (coming out at 1010 meters per second just to drop to 550 meters per second after just a second of flight time) and the crazy damage nerf to most 20mm’s.
This means that the only good things that F-5s had has been gone for almost 2 years
I request the F-5C to be moved to 10.0 without flares and probably no missiles either (no, the f-5c flight model does not overperform, learn to use your superior thrust weight ratio against it)
Even the four cannons of the f101c deliver white text on dead stalled enemies.
I will take a GSh23L any day over the M39 cannon.
