Default need help

I'm building an Edge 540 from scratch, the wing span will be 80'' fuse is 61'' and a 45cc homey with CH ignition. I need help with the size of the vertical stab and the horizontal stab. The horizontal that I made for it is 26'' and it looks too small. Is there a formula for this? If anybody knows anything about how to get this information. please let me know. Thank you!

did you enlarge small plans to the wing span, percentage wise ? if so use the same % for the fin/rudder and it will fly good. dick
