RE: Excelleron 90 need info
That's a lot of reading, and I have read it all. LOL
7 1/2" is the CG most people like on this plane.
As for the control throws, I think about 10MM up and down are good for the ailerons and elevator and some more on the rudder.
If I get a chance I'll measure mine and let you know if you don't get it in the air first.
Great plane, what engine did you get/put in it.
