This review was actually requested of me some time ago, back when the Chain Lightning was a fresher face around these parts.
It was slow in happening because...unlike her lower tier sisters the XP-58 didn't perform well for me to begin with. In particular her guns just refused to connect with any target for me for the longest time. Then Waffles pointed out to me that my problem was likely the terrible dispersion of those guns and that I should violate my own rules in this case and utilize Aiming equipment and even accuracy pilot skills.
That does indeed make a large difference with this bird and I began to see a turnaround in my performance in her soon after I made these adjustments. Aside from the silly stupid bad accuracy of her main guns flying this aircraft feels like flying a P-38 that's been on a heavy regimen of warplane steroids. Being an American heavy, she's meant to do battle with other heavy fighters and win the high altitude fight before joining the scrum at mid altitude where her 50 cal rear guns can lay a hurting on already damaged dogfighting lights and her quad 37mm frontal cannons can evaporate anything that holds still in front of her for longer than a second or two.
The quad forward cannons are also tailor-made for wrecking the battle for enemy attack aircraft. You have enough firepower and resilience to clean out defending enemy AA installations and can eat attacker tailgunner fire all day long.
Overall, not the *best* plane at tier VIII, but she is still very good at what she is meant to do.
