Don't blame the tools.

Set it up with the nose wheel pushrod linked to the INNERMOST hole on the servo arm & the OUTERMOST hole on the nosewheel steering arm. After that, if you can't deal with the problem, it is you (& maybe your instructor), not the airplane. More practice makes the problem go away. Literally thousands of pilots have learned on this plane & it really isn't much of a challenge

Sorry for the tone of the message --- but ---.
