Sewerdude...

I use one 5945 on the rudder of my CAP. It's plenty. You don't need two. I only use 4.8v on this plane. Although, if I could do it again I'd go 6v. But one rudder is plenty. This plane will KE like no other and flat spin great also. Very powerful rudder needed on those stunts. I can do them fine.

Good luck.

Thanks
Barry
