I concur with the other posts that your setup is nose heavy. Here's something else to try... you have a +1.0 on the Tcan. Mine was set at 0.2, others have used 0.3. I believe that the more incidence you have on the Tcan the greater nose down pitch to the airplane resulting in the need for more up elevator to trim for level flight. Any lifting force you place on an airplane BEHIND the center of lift always pitches the nose down. I think that the 1.0 on the wings is fine as well as the 0 for the stabs. I also think that the batteries need to be further aft. I completely understand that the V1 and V2 are different, but your plane is doing exactly what mine did on the maiden flight. My solution was changing the Tcan and moving the batteries aft to be inline with the wing adjusters.
