1:1 thrust is fine for a non-performance application. Energy management is still very critical because there is nothing left to counter drag once the nose is pointed up. All my old planes with 1:1 would generally climb vertically about 100' from take-off or 200" from high speed and then just stop until it fell over. All that was a long time ago when planes tended to be very heavy. Nobody has to learn energy management these days and it shows by how many crash when their engine quits.
