Does any one have a sig something extra? If so does it knife edge well? i am looking to get a couple to do a formation flying routine .Please let me know. thanks[sm=bananahead.gif]

Build a bigger rudder and it will knife edge fine

Mine will not hold KE flight. A bigger rudder would help. Maybe look at a Twist. You can buy two for the price of one SE. It has a much larger rudder and does a decent KE. Both plane however are fairly short coupled. If a majority of your routine is KE I would find something with a longer fuse. A UCD3D does a good knife edge for example.

Hey David what size engine are you running?

My ARF version would knife edge fine with high rudder throw and the coupling was minimal. If you are concerned though, a larger rudder might help as others have suggested.
