Bill,

“All comments are welcome?”

I do use fixed “glued in” bolts in the wooden engine bearers, see the picture.

I can change the down thrust with sims, layers of glass/epoxy between the wooden bearers and engine. You can see them on the picture, all red!
Adjustment of that depends on several facts as, inverted flight /normal flight, fuselage shape, weight etc.

Down thrust is for me the last adjustment after trimming the model, CG/incidence of the wing/weight, neutral position of elevator, balance of wings etc.
Most important for adjusting downthrust I think is normal and inverted flight.
You need an adjustment for that and I do use the down thrust as on the plans, need a little bit down in inverted flight. I prefer that.
Some people do pull also the elevator in normal flight but I think that does not change the needed downthrust.

Side thrust is another story.
There are three main facts that makes adjustment of side thrust necessary.
1 Difference in P factor in normal and inverted flight.
2 Difference of slipstream of the prop wash in normal and inverted flight
3 Torque of the engine
Because I do find inverted as important as normal flight I do use 1 ½ degrees side thrust and that's right for me (it was a choice by experience).

This is with a 61 engine, OS Max 61FX or MVVS 10 ccm (60) and 13 x 6 propeller.

My model is a little heavier than the standard Taurus (15 %) but that doesn’t change these values I think, I need a few porcents more speed for that.
If you want more explanation of these I can look for posts I already did make in my thread “Redesign and reconstruction of the Oldest Taurus on Earth” if you want.
Success with building the Taurus.
