If the nozzles are rotating with the elevators, the thrust may actually be pushing the plane into the ground, thus requiring much more speed before lift off.
I would think the opposite - TV would supplement the force exerted by the elevators to rotate the plane during takeoff.
I think something to try is to apply slight up elevator while the plane accelerates, let the wings start to generate lift, and allow it to get off the ground on its own, just like the real jet - then you can jerk the stick back for a steeper climb. That would certainly avoid any tail-scraping, too.
