Greetings and welcome to Mobius, Commander Lon Mackay
An FDL should put you in a very strong position against a Cobra MkIII, so if you are having issues it could be either your weapons load out, so first question what are you using?, or it could be that you are trying to take on wings of enemies which is not to be recommended especially if they are Cobras.
Now it may be that they are using railguns or PAs, these are very nasty weapons so manoeuvrability is your key here, try to avoid jousting (flying directly towards that front of your enemy), use of your lateral thrusters helps with this.
Please feel free to ask as many questions as you like, you'll find everyone one here is more than willing to help out.
In the mean time...
