I am flying a Morris Hobbies Giant Sudokohi, which is my favorite plane. Weight is 15lbs on inacurate bathroom scales, 1800sq + inches. The 2.4 is just now broken in. Running a 18x12 and sometimes a 20x10 Zingers with no problems. The plane floats in at a walk speed for landings with flaporons. I cant say enough good things about Brison engines as I have 4. 2.4 two 3.2s and a 4.2.
