well, knife edge didnt change a bit, it will knife egde witout losing altitude with less rudder imput, but if u want it to climb or is u pull full rudder, its the same as before...

also has more elevator coupling, i used to use 10% mixing, now im at 13%...

the rudder is..... ill sen pics... but 1" higher, 1" longer at the back-top, 2" longer at the back-bottom, 1" lower at the front (so a made the vertical stab 1" smaller)...
