I have been flying the exact set-up you describe. Best flying plane i have had (over 30+ year). I can fly it very slowly with minimal or no risk of snappy stall. I am running a 14x8 APC. I did not feel that 13" prop felt right. Also, check the relationship between the wings and the overall incidence with respect to fuse. My CG is at 4 1/8" (per plan).
