For learning dog fighting I highly recommend getting into the match play arena with a friend and keep on fighting.
Never HO will be rule one.
Film your matches. And reflect what you could have done better.
Do not worry about shooting your enemy down. Fight for position instead.
Watch your E state, always look when you can gain more than your opponent. If you have more you can put the fight into the vertical.
There are several good merges, look what works good for you. For me when merging I dive for speed and initate a climb for position right for the actual merge. I look at my opponent if he climbs with me I turn into him and I make sure I have around 200 indicated airspeed. Before we merge again I try and buildup as much speed and make another climb. In most cases I win the e fight or win the position. About now we should both stal but if you can control the stal and be above your enemy. You dictate the fight. If your opponent keeps diving don't follow, but look if you can gain a better position on him again and push him in an corner. BnZ him basically.
I used to talk to myself when I was still learning. I kept predicting where my opponent would be next and what he would do afterwards.
I would fight you in the MPA arena myself but we are in different timezones.
I think FLS can help you with the basics pretty well.
The next best thing I can recommend is watching Vudu's older videos and linking you to my old duel with Tactus.
