Hey Chuck (I sound like Peppermint Patty!) I usually use an APC 12x4 as I liked it better when I first got the plane and compared hovering pullout between it an APC 12.25x3.75 and a few others. I recently broke my only 12x4 taxiing too fast with full up elevator into the wind!

ya, pop up and stall onto prop. So now I'm using the old 12.25x3.75 and can't tell too much difference although it has been awhile.
Flew the Twist again for a few flights today. Got the feeling back for the Twist and got it torque rolling pretty good as it blew down the field. Had a little trouble with blenders until I started adding power a little earlier before I started moving ailerons from full left to the right. Don't remember having to do that before... maybe I've just been on the sim too much recently!
