I think the twin fuselage configuration is about the best. The extra center section keeps the wing loading down and the plane is streamlined and usually fast. I have a clunky, twin-fuselage Sky Raider and it's fast so I would think your sleeker SE would be really speedy. I'll also bet you have tons of vertical. I am using APC 11-5 props, by the way. They seem to perform better than the usual 11-6.
