So any tips for aiming in realistic and sim?

[Ant26587]

Really having problems with keeping my sights steady, everytime I try and aim my sights wiggle around wildly like my pilot has arthritis which means my tracers do absolutley nothing for me because I can't aim where I want to.

So just end up wildly aiming and firing at the general direction of where I want to shoot...:/

Anyway, any tips for those in the know that would kindly like to help out a flightsim newbie?
