Oh Ok. I see now, my mistake, failed to engage the H/O aspect button when attacking jets head on with Vikhrs.
I did a few more tests in ME firing at jets from the sides and rear without engaging the H/O button and it takes on average 2 Vikhrs to kill a jet.
So not activating the H/O aspect button when shooting at jets head on with the Vikhrs can result in minimum damage being inflicted to the enemy aircraft.
My problem was not related to the high amount of damage it takes to kill a helo(thats already a known and different issue).
I deleted the video since the test results were based on...ummm...an unusual situation with helo damage.
