my opinions on the expo is no more than 45 % and i try to go lower

example for me that hovering is harder with more expo along with rolling harriers

for example on a 3D capable plane i would start with 35 % on the ailerons and 40 % on the ele and 30% on the rudder and if the plane was to twitchy i would increase the % if i felt like i had to move the stick to far for the plane to do what i wanted to do decrease the %

edit:these number are with a semi fast servo travel speed of .13 if the servo is slower like .2 i would decrease the expo

example of this is a mini funtana with the Jr 241 servo it has a .23 travel speed and i used no expo on the ele and rudder and 20 % on the ail
