A dramatic finale to the lunchtime kick-off at Loftus Road saw the Reds turn around a one goal deficit, given to the R's by Charlie Austin, thanks to a Henri Lansbury penalty and a debut goal for loan striker Nelson Oliveira.
"I felt we were the better side and deserved to win the game," said Dougie Freedman afterwards.
"We played some fabulous football in the first half and took the sting out of the crowd.
"QPR had a 15-minute spell in the second half but, even when it was 11 versus 11, I felt were we playing well.
"Obviously the sending-off helped, although I felt that but for a trademark goal from Charlie Austin we were the better team."
