The best thing to do is to learn what forces are involved in the hand launch and the techniques and control inputs needed to control, and/or work with those forces.

That's 'sort of' true but flying a plane that has very marginal thrust is actually really hard because the plane is constantly flying on the edge of a stall, and even doing a gentle turn can cause it to fall out of the sky. Having a little thrust in reserve does make a plane much easier to fly.
Having good thrust also makes hand launching much easier because the plane gets up to flying speed quicker, even if the launch is poor. This is especially true for heavier faster flying models where it's hard to get the plane up to flying speed by throwing alone.

With my 3D models all I have to do is point the plane up, open the throttle, and let go... and away it goes straight up Try doing that with a plane with marginal power.
