I don't want to seem presumptuous in a first post, but you are aware that you can easily break your aircraft and die doing 80deg turns? The load factor in a 60deg coordinated level turn is 2g, but an 80-degree-bank turn requires 5.76g at a constant altitude with coordinated rudder. That well exceeds the structural load limits of your aircraft. Further, to maintain a level 80deg turn will increase your stalling speed to over 100knots. Loss of control in steep turns due to a high speed stall, flick and spin, is one of the biggest killers in aviation........I've got used very quickly to 80 degree banked turns "because I can".
