rudder responsiveness with little dihedral
im almost done building a 1.5m electric glider, but i have only made the wing dihedral 4 degrees total. i realize that this make the rudder less responsive, and i cant change the angle of the wings anymore since they are epoxied together, so i have two questions:
1: will a bigger rudder make it more responsive with such a small dihedral angle?
2: some slope gliders/ aerobatic gliders have no dihedral, what makes the rudder responsive? is it the air speed, a bigger rudder or a combination of both?
here are some specs
weight is going to be around 13oz with motor esc etc.
total dihedral angle: 4 degrees

Yes, it's a combination of how fast the air is flowing over the displaced rudder and how large the rudder is.
Just make it bigger in small increments till you feel you have enough control authority.
Control surface sizing questions/issues seem to be coming up a lot lately on this site.
Personally, I'd rather have too much authority than not enough.

Go for a big rudder with that reduced dihedral. You can always reduce the amount of throw if you feel it is over controlling, (yawing).

Induce roll the wrong way Keeping the weight as low as possible will help with the turning
