needs full rudder on the take off roll in zero wind, which is wholly unacceptable for a trainer. If true, it's unacceptable for, ahem, flying of any sort, because what if you get some, ahem, wind from the right?
It pretty much needs full rudder to be applied to keep it straight in nil wind. In the event of a cross wind I've seen people line up at an angle, rather than nose straight down the runway, that way any extra yaw puts you straight and you still have some directional contol left.
Truely awful design.
