Two portals. One gun. Whatever speed you carry in, you carry out.
Fall far, come out sideways, and fly.

Portals only stick to lit panels. Momentum is conserved through
the gap, so a long drop into a floor portal becomes a long flight out of a wall portal.
Red fields dissolve portals. The void does worse.
