From experience with a number of "V" tail rudder/elevator gliders I am certain that the angle on the Invader's tail is too shallow to give adequate rudder control. I found that the maximum included angle of the "V" for decent rudder effect is 110 degrees, i.e. each tail half inclined at 35 degrees above the horizontal. Spring centred rudders with pull action certainly sound the best bet on a model of this size.
