Precisely it is exactly like reducing the throws and since many folks especially when new tend use excessive throws longer sticks will have a smoothing effect.

You can see the same thing in full scale craft where early aircraft tended to have rather long sticks but in some modern aircraft both homebuilts and some military with the shortest possible sticks controlled just by wrist action.

If you look at most early helicopters such as the bell 47's and Hiller's Which had incredatably long production lives the earliest had the longest sticks possible with overhead cyclics and later versions had progressively shorter conventional sticks.

If you look at the US military training gliders of WW11 such as the Sweitzer TG-3's, the Pratt Reeds and LK's among others the sticks were very long almost up in front of your face. They were intended to be used with two hands with grips about twelve inchs long you could slide your hands up or down to acheve the 'feel' that suited you.

Of course there are other mechanical factors in the linkage geometry mix but stick length is very much a factor.
