ive had a try with lots of differet setting and ive found that there is a side effect of increasing KE lift that the rudder becomes less and less efective untill the point where at 100 on the lift the rudder, even at 60 degrees and 100 propwash its totally useless. ive found 5 KE lift and 60 degrees rudder + 100 propwash is a good balance
