Need tips regarding jets

I just researched f84B for US and for the past few games I am having a really difficult time flying it. From the few youtube videos I watched, I could only get that you need to maintain speed. I try to maintain speed of about 700 kph IAS.
Most of my engagements have been headons . I am also having difficulty on how to properly climb in this thing. Also most of my deaths have not been being killed by player but pilot blacking out or crashing while chasing a plane.
I just got into jets so any help will be greatly appreciated.
