@RapidKebab One engine must be inverted to counteract the rotation. Switch W and S on one engine.

I tried to upgrade this with significant gearing, so I had to move the rearmost engine shafts one step back, however, both that and any attempt at props I do seems to reintroduce some extreme prop torque. How do you avoid this in this design? it feels like it works perfect until I dare change where those shafts and engines are?
