i can't (nor have i ever) been able to fly as i like to call it 'Dumb Thumb' I've always held the sticks between my fingers. i also have the sticks as short as possible, my flying buddy has his sticks all the way out and actually put longer knobs on as well and when i fly anything of his the long sticks make it feel like it has a ton of expo dialed in (we both use PCM 10X Heli TXs). lengthen your sticks some, this makes your fingers have to move farther to get the same input, it's just like expo, but it's linear.
