welcome, I just posted this over at other new VTOL pilot so i'd might as well share it here too
Three main tips for new VTOL pilots is
1) Stay has high as you can, this keeps you out of range for some weapons, and the ones that can reach you will like RAC2s and MG fire will spread out for decreased damage.
2) Don't hover in one place for too long, you'll just attract gauss bolts flying at you :p
3) Learn out to go full trust while making a hard bank (without crashing of course). This will help you avoid missiles and evade clustered AA fire.
