What criteria does a plane have to meet in order for aces high to perk it. Is it production numbers, last i remember there werent many nik's produces, but then there were almost as many f4u4 as there were f4u1ds. BUt then there werent many la7s with 3 cannons, a thread awhile back had the numbers on la7s produced with 3 cannons, i dont recall but there were in the 100's. Last i heard f4u1c was perked because there was like 20% f4ucs in the arena, but how long ago was that. Im pretty sure the times have changed since then. Whats the current numbers now, i noe la7 ranks up there high.
