I'm using a OS 50 with 11x7 turning about 13700 rpm. SIG 15% fuel.
The plane fly quite fast and have good vertical pull although not unlimited. I've try to enter with half throttle, apply full rudder and throttle up.....dosen't change anything, the plane still drop. Is this conclude that my plane just wouldn't knife edge?

Are you sure that your rudder linkage is up to the task and not deflecting under load during flight? I would forget about props etc until you are 100% sure that your servo and/or linkages are able to deflect the rudder fully while in flight. You aint never gonna knife edge if your rudder aint movin'
