A Rudder isn't necessary for a Control Line plane.

I am with you with the side area, even the Genesis has added side area via a long thin fin.  Interesting though, all of Bob's newer designs have rudders (really vertical stabs).  I wish I had the time to put huge "rudder" on a plane and whittle away at it till I found the sweet spot.  My Trifecta design has about 50sq in of "rudder", Endgame about 5. Both fly extremely well. Neither of them display any of the problems a rudder is supposed to cause or cure.  Both have -0- offset and both have CAM rudders.  The one with the larger "rudder" stays tight above 45 a bit better, but that could be due to a thousand other reasons.  I corrected that with the timer on the small rudder one.

Okay, Ty caught me with the disguised side area thing. Attached is a photo of the Genesis LC, which has the disguised side area and a couple of small twin stab tip plates (otherwise known as twin rudders). This thing grooves like a freight train and turns amazingly well; due, I think,  to the lack of spanwise flow off the elevators. Yeah, I know, it's not a new thing...

Later - Bob
