Ok found it! And I used only triangle tool yay! 
Others, note it please
You already know how many studs should it be tilted, the pin should be "somewhere" on the orange axle:
Add helper mirrored arm/lenght on the axis:
Construct a triangle, in this case the angle is 14.47751 - you can skip the helper:
Because you know the angle, tilt the opposite arm but with negative value, you can also delete the helper:
Move the upper base to close the shape:
I really hope it will be useful for other users in different models
And the plane problem has been solved
