I dont think radios offer that option on them. Maybe try adding some down elevator trim to compensate for the upwards action. My foamy tries to fly upwards for some reason now to, but I think thats because of my ailerons not being correctly aligned. But, I fixed the ailerons now, so I think that might have fixed it. I have to wait to see how it flies, and maybe fix something else if it still flies goofy.[&:]
