I have trouble seeing a 1%-2% throttle to elevator mix causing a problem
As in F3A planes, mechanical adjustments first and then small mixes to fine tune.
As my Turbinator (v1 prototype, very low downthrust angle) has a Cheetah (lots of throttle climb), I'll try the mix in the spring when flying season starts again
If it splats on a throttle up go around, I'll post back here
It's your airplane of course but I suggest you not follow through with that plan. Electric motors react much more quickly than turbines, making solutions for the former quite different from the latter.
The thrust angle solution exactly proportional, in sync with the cause of the problem, and time proven over hundreds of installations.
A throttle-elevator mix will be both out of sync with the thrust and vary with airspeed, creating two new problems while solving none.
