Default RE: Tricycle gear question.

I would rebend the main landing gear (spread it apart so it sits lower and bend the axles in for a tad bit of toein) so that the airplane sits level on the ground. The engine downthrust (if 2degrees downthrust is built in the nose of the airplane) will cause the nose gear to lean back at two degrees.
You can have the nose gear straight down or even slanted or "raked" forward by tilting the STEERING AXIS forward so long as the steering axis, when projected to the ground is at a point AHEAD of where the wheel touches the ground. This is called POSITIVE caster by definition; and it is used that way on motorcycles, cars, airplanes, and vehicles where steering is required.
This was explained in LouW's post earlier, but I think it was not clearly understood.
