Yes, it looks good, I think I won't need to make more space for the Hatori. Only a hole just next to the landing gear for exhaust will be needed. Which prop is good with YS, for 3D and for F3A? This plane is just right for me, a F3A plane, which is able to do also some 3D. Servos will be DS821, will they be fast enough for 3D, too? I could use them at 6V because of the CC BEC, so they would be 0,15s.
