RE: BRIO Construction by the numbers
I think everything is 11 or 12 degrees on high rate, but I think I bumped up my ailerons to about 13 or 14 degrees and set up a snap rate in addition to a spin rate. I really admired the snaps that Wolfgang Matt did in Romilly a couple of years ago, and am setting up my plane to do the same. I'm like 75 percent on low rate elevator, probably about 85 on snap rate for elevator and 100 percent for spins. The extra ailerons put me at about 70 percent on low, and like 100 percent on snaps and spins. I keep remembering that I can stay on low rate for all rolling maneuvers to include the one roll circles and rolling loops due to the rudder authority on the Brio.
I took several ounces off the yellow Brio to get something that was a little closer to my blue Brio's. They are still about 9 to 11 ounces lighter. It makes a big difference in the amount of rudder and elevator needed during rolls in particular, and a plane which is half to 3/4 pound heavier snaps much differently as well. The yellow plane is the winter trainer and backup.
