True 3D's are trimmed with slightly tail heavy which make them snappy but be prepaired. They are not trimmed to be rock solid Pattern Planes so you need to understand the difference between 3D and Pattern. I think a Pattern plane trimmed slightly nose heavy and with a slight amount of down trim is capable of a wider range of aerobatics from slow roles to flat splins, flat turns, inverted flight, Snaps, etc. The slight down trim helps to keep you in touch with the plane because you must continually imput slight up to fly level. Also with Ballance you need to consider too much of too little down thrusts and how it can confuse its effects with ballance. Frankly the other thing is the size of the plane. A 90" wing 3D verses a 48" 3D is a matter of scale and speed. The larger the plane the slower the movements occur and as size decreases things speed up in scale terms. IMO
