Let me preface by saying my eyesight aint the world's best.
It appears to me that all tracers take the same trajectory and arc, despite the ammo loadout of the plane I'm in. Granted, I fly the Typhoon a lot, but put me in a Fw109 A8 and the 30mm cannon round tracers appear no differently than the MG tracers. Simply logic suggests the 30 mm's are gonna drop like bowling balls while MG rounds take a much flatter path. Do tracers mimic the same trajectory of the specific ammo, or just indicate a "general" ammo stream?
