longer = more paddle leverage = faster response - shorter lever, less response but more load on servo - if you could find some smaller paddles you could achieve slower control with less servo load
for the falcon 40, you can replace the cf flybar stick with a piece of align tail servo wire and have a fixable metal flybar - adds a touch more weight so slower control - be sure to flatten the 4 areas that will be contacted by the screws or it will wander
had to do that on the tiny little walkera 4#3 as i kept snapping off the flybar up inside the brass holder and it was a bugger to get it out -
