I don't know. You are dealing with stuff out of my league. I know Arco Joe changed his rudder to quite a bit smaller on his 60 size. He thought it was better.

I just fly mine the way it is. I have a couple of mixes going but that's why I have a programable radio. But I can fly KE without mixes too.

I just love these planes. They are my favorites. I can't find much fault.

Thanks
