Degrees of Flap

What are the degrees of flap for a model III wing at full flap? 15?, 20?, something else?

And for those who use flaps on take off, how many degrees (approx) do you generally use for shortest take off?

What I am trying to figure out is where is 15 degrees on the flap handle? I use 1/2 flap then pull full flap to "jump" off the runway. What I don't know is what degree of flap are those settings on the model III wing?

You are coming to the factory fly in aren't you?

I used an angle finder to find and mark the degrees on my flaps. I rigged my flaps so handle full down is zero. I drew a line bisecting the flap on the inboard end of the flap (the flap end rib) to hold an angle finder on. If you have the flat bottom flaps you could measure the angle pretty easily.

The Warp protractor is a great idea.
