Every year I am starting to understand less and less how to unlock vehicles in those events.
from what I've read.
You get a broken I-180S. You do a diagnostic test flight to find it faults (However that will work idk)
After the flight, you attempt to diagnose the issues
And get extra Toolkits for it.
You find out what is wrong (I assume 5 Parts will be broken) and this is different for every aircraft.
You play a match of Arcade or Realistic at tier 2 and achieve 10 minutes of play time with 50% battle activity and get a chance to get components and tool kits.
Components need to be diagnosed before use with tool kits
Multiple components can be made into a part which then needs to be diagnosed as well
You fit the 5 parts into the broken aircraft and you have a repaired I-180S.
The first one you repair gives you an I-180S Coupon which can be exchanged for German VFW or Pr112.
Any more broken I-180S' repaired will give you a vehicle coupon which can be exchanged for any vehicle in the lineup. 2 is required for the higher tier vehicles.
It is estimated it would take around 12 odd hours to finish one vehicle. But I don't trust those numbers.
You can trade spare/useless components that you have for useful components on the marketplace.
The event seems easy, but tedious.
