Default Using flaps... how much elevator??

I received a lot of good replies to my first question.....
http://www.rcuniverse.com/forum/m_50...tm.htm#5252455
Now that my flap installation is complete, and since I have never used flaps on ANY of my planes..... I am wondering how much elevator should be dialed in when dropping the flaps for landing? Let's say @ 45 and 90 degrees of flap. This is a Skybench Aerotech XL Big Bird, electriefied, and has a flying weight of about 59 oz. I ended up making my flaps 20" X 1.75" each side, and a stock size elevator is on my Bird.
I am assumming that this amount can vary, even on the same type of aircraft. I am looking for a "safe, approximate", setting so I have no ....... let's say..... unwanted surprises. (Stalls, or worse, a sudden dive for mother earth)!!!
