If you bent the torque rod before it was in the model and didn't use the dogleg... its fine, don't change it.

The place that NOT using the dogleg can be a problem is when putting it into a model that was flying (or flyable) and you wanted to change the differential using the bet torque rod method. The dogleg helps prevent you from damaging the model when changing the torque rod angles.

If it ain't broke... don't fix it.
