my problem with twisty's is the rudder gets actuated as i moved the stick and or I'd be losing E because of the twisty rudder ....
Now this cost me alot of fights .
W/ Peds i can control the input,, better gain in spiral climbs , maintain more E and actually win a few fights .
Go off line of to the TA and watch ur plane in f-3 mode or watch ur films in f3 and see what happening to your rudder while going thru manuvers.
