With a plane that weighs only 2kg and a .46 in it, I don't think you will have trouble getting it to fly.
Trimming and handling is another matter entirely. Though you haven't mentioned a wingspan.
Work out your wing loading, weight/wing area, that usually gives an INDICATION on how things are going to go.
More wing loading = more speed to fly, higher stall speeds, etc.

Add enough power and you can get a brick to fly.
