RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
Here are some pictures taken at the flying field. Of particular interest in the picture of my rudder. This shows the rudder at full deflection. I also have 75% of expo on rudder as well. I figure it's about half the throw, and 30% more expo than what I had on my single prop Integral.
If anyone wants to ask me why, I have to admit that right now I really don't know for sure. There's something about using the Contra Rotating Drive that has made the rudder much more responsive.
