I set the new Curare up using techniques I'd read about to maximize mechanical advantage. I used 3151s throughout. What I found was that by only using 5/16 of the servo arm and 5/8 on the control surface I use very little expo. I'm using none at all on the elevator, 10% on ailerons and 15%of rudder. The expo I do use is basically to keep my nervous thumgs from moving things that don't need it. The 3151s don't eat the batteries like some of the earlier digitals I've used in larger planes, too.
