Redknapp has inspired previous 'great escapes' with West Ham and Portsmouth and the experienced 31-year-old winger believes he can do the same at Loftus Road.
The west Londoners have drawn all three games under Redknapp since he took over from Mark Hughes, who was sacked last month.
The Hoops entertain neighbours Fulham on Saturday without a victory in 16 games and eight points from safety, but Wright-Phillips is confident of escaping the drop.
"It would be massive for us," he told The Daily Telegraph. "We are a great squad of players, great individual ability but, at the moment, it has not come out as a team. It sounds small but, for us, it's a massive positive that we haven't lost in three games.
"We are in a position where we have to fight. It's obviously hard to change it around but I do think things are slowly changing.
"The belief has come in and it is looking good. All that matters is just to get QPR out of the situation we are in because the club and the supporters don't deserve it."
And Wright-Phillips insists Redknapp is the perfect man for the job and is already getting the best out of his star-studded squad.
"Harry is great at making you believe in all your capabilities. He gets you back to what put you on the pitch in the first place. He tries to bring back what made you. He always reminds you of how good you are and the player you are. He lets me know the abilities I have.
"Most, if not all of us, only started playing football for enjoyment.
"He encourages you to go out there and express ourselves and enjoy our games. We work hard; we want to win as many games as possible but just play with a smile on your face."
