Plane: RV-4 with Lyc O-360
Initial prop: Sensenich 2-blade FP wood.
New Prop: Catto 3-blade
When the swap-out was finally ready to fly, I noticed the ball on the T&B was out to the right by about 1/2 ball diameter requiring constant right rudder input which increased with airspeed. I installed one of Avery's wedge rudder trims and that brought the ball almost center, but now I have a heavy right wing. If let alone, the plane quickly enters a downward spiral of increasing bank, airspeed, etc.
Now, with the 2-blade Sensenich, the plane flew hands-off, straight and level. I am tempted to go back to the Sensenich if the trim situation cannot be addressed.
I could use some ideas and commentary on this.![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
