I have the Aresti and put a 46FX in the nose. The plane is noseheavy no matter what. To balance mine it was either cut a hatch and move the battery behind the servos or add 2 oz of lead to the tail. I chose the latter and have not had a problem. As far as 3D there is no easy way this plane could do maneuvers like this. At slow speeds the flight characteristics turn to crap despite what that article says in Model Airplane news. I think the Aresti is made to keep moving at a good rate and with how clean it is that's not hard. Also if you plan on doing tumbles and snaps with this plane I'd put flying wires on it. I think it and the Venus are best described as sport/pattern planes.
