The `exploded view ` of the mod. is looking aft,and also the photo at #54 on that thread.The bobweight is forward of the stick pivot,so under `g` loading it pulls down increasing the `stick-force per G increment,and the same for negative G.In the TF51 case it may be further back as it`s got full dual controls.
I would think that for the weight reduction for racing there would be a lot of extra hardware,ex-mil, that could be removed without touching the controls,or maybe just reducing the bobweight somewhat..
