I believe it is. Equally important is the placement of the flight controller as close to the frame cg. Adding gear should be functional for visibility and clear radio transmission for FPV etc... But then use none location critical equipment to balance the tri, such as the battery, equally front or back and side to side. A flight controller can compensate to a degree but efficiency will drop if your frame is unbalanced. A tail heavy tri will fly but the rear motor will have to work harder to level off. A good cg and balanced multi will hover hands off without trimming to compensate and fly longer on the same charge.
