Just some concideration for you to think about. The Venus is a pattern plane aerodynamically designed to perform a certain way. Servos bulging out of the sides may effect the aerodynamics. Can a single servo be mounted in the tail inside the fuse? I too have relocated servos to the tail of a plane to eliminate rod flex and assist in ballance of generally too large of an engine installed on most of my planes. A lot of 3D planes come with tail mounted servos but they generally fly slower and the drag induced by the externally mounted servos have little effect on the desired performance.
