Assume the Niki has a significant E advantage <altitude> . What are the best ways to handle this ?
start a turn as if you don't see him. as he gets closer, pull tighter. if it looks like he's following, pull to near blackout, then top rudder and aileron, roll over the top, you should have a very quick snapshot at him.
other possibility. turn into him. shorten his time to get a guns solution. try to be in a shallow climb as you turn, so as to lessen his advantage. i thnk the nik looses almost 1k ft on each zoom? if you can grab 500 to 1,000ft on each evasive, you'll be pretty even with him fairly soon.
they're not perfect, but have worked for me in the past.
