Control throw philosophy- pattern
Why use more control throw than you need? Someone recently asked for my control throw setup on the FOCUS II pattern airplane. The discussion triggered thought on some experience I found that may be helpful to you. I utilize low rate for normal flying and high rates for stall turns, spins, and snap. This is a setup that is just a personal preference. It was once suggested to me that a single rate is preferable- providing control at all times without the worry of dual rates. I tried this and found that there was just too much contol around neutral, and when a significant amount of expo was put in, roll rate and radius segments became inconsistent. The "happy medium" was a single dual rate switch (activating the ailerons, elevator and rudder dual rates simultaniously, through the COMB function on the 10X). The additional expo on the high rate provided nearly the same feel around neutral for either high or low rate. This means that if a little elevator was being held, for example on the way up for an avalanche, that there would be no movement or change in radius of the loop segment if the dual rate switch was activated just prior to snap roll. Any case, here are the settings for the Focus. The expo for low and high rates provide nearly the same feel out to about quarter stick.
Ailerons low rate 9 degrees up and down. Expo 19 percent. High rate ailerons 11 degrees up and down, expo 26 percent
Elevator low rate 8 degrees up and down, expo 25 percent. Elevator high rate 14 up and 13 down, expo 50 percent.
Rudder low rate 1 inch (measured from the top of the rudder) with 44 percent expo. Rudder high rate 1 3/8 inch, 70 percent expo.
Normal flight is low rate, stall turns, snaps and spins on high rate.
