New-boys Patrick Agyemang and Rowan Vine were on target, as Rangers eased to a comfortable 2-0 victory against out-of-sorts Barnsley.
In front of the biggest crowd of the campaign, the R's were good value for the two goal win, which extended their unbeaten home run to four matches.
In a first half which largely flattered to deceive, Rangers were perhaps a little fortunate to head into the break with a two-goal buffer.
Agyemang opened the scoring inside the opening five minutes with a tidy finish, before Vine made it two on the stroke of half-time, after the former Preston man played provider.
The R's went on to dominate the second half, with Martin Rowlands going closest to extending the hosts' advantage on a couple of occasions.
Following last weekend's 2-1 defeat to Sheffield United, Luigi De Canio opted for the guile and pace partnership of Dexter Blackstock and Agyemang in attack, but there was no place in the squad for Gavin Mahon, who missed out due to illness.
Tykes boss Simon Davey gave a debut to recent recruit Miguel Tininho, while Brian Howard overcame a slight knock to start in the heart of the Barnsley midfield.
There was an early scare for the hosts when debutant Matthew Connolly required lengthy treatment from physio Paul Hunter following a four-way collision on the halfway line.
Thankfully the right back emerged unscathed, and from their very first attack of the game just 60 seconds later, the R's took the lead.
Vine's centred ball found Blackstock, who in turn played a sublime reverse pass into Agyemang. The pacy front-man beat the onrushing Heinz Muller to the ball, flicked it over him and headed home into an empty net for his second in as many games.
It was a fitting reward for Rangers' impressive start, which yet again owed much to the battling qualities of skipper Rowlands and the returning Mikele Leigertwood in the R's midfield engine room.
Buoyed by their early superiority, Rangers went in search of a second, with Fitz Hall heading an Akos Buzsaky corner a yard wide in the 13th minute.
The Tykes, to their credit, were enjoying plenty of possession, but the Rangers back four, marshalled by the domineering Hall, were rarely tested.
Brian Howard's 24th minute effort from distance, which flew well wide of Lee Camp's right hand post, was the best Barnsley could muster, while at the other end, Buzsaky's cross from the by-line just evaded Vine.
Rangers saved their best move of the half for the final minute, as Vine notched home the all-important second goal of the contest.
Agyemang, who impressed on his full home debut, played provider, as he and Vine twice combined to tear the Tykes defence to shreds.
Faint appeals for an offside flag fell on deaf ears as Agyemang unselfishly squared the ball for Vine, and the wide-man did the rest, firing into the back of the net with aplomb.
Rangers began the second half in determined mood and but for a late stumble, Rowlands would've had the goal of the season all but wrapped up.
Picking the ball up just inside the Barnsley half, the midfield maestro jinked past challenge after challenge, only to lose his footing as he attempted to coast past goalkeeper Heinz Muller.
Despite seeing his effort from an acute angle eventually cleared off the line, the Loftus Road masses rose as one to salute an extraordinary individual run.
At the other end, Camp saved with his face to deny the roaming Jamal Campbell-Ryce, after Hall's slip allowed the nippy winger to bare down on goal, before strong appeals for a QPR spot-kick were turned down when Blackstock was dragged to ground by Dennis Souza.
In complete contrast to the first period, the chances were now coming thick and fast, with Connolly getting in on the act when his deft clip flew inches wide of Muller's right hand upright.
Leigertwood's 59th minute blockbuster brought the best out of the overworked Muller, who palmed the ball to safety, before Tykes substitute Kayode Odejayi somehow volleyed over after fellow replacement Rohan Ricketts sent an inviting ball to the back post.
Rowlands' all-action display very nearly got the goal it deserved in the 76th minute, with a move direct from the Harlington Training Ground.
Buzsaky picked him out on the edge of the box from a corner, and Rowlands took one touch to set before drilling his low shot inches wide.
With Hall seemingly struggling with a calf injury, De Canio even had the luxury of welcoming Michael Mancienne back to the fold from a seven week lay-off in the final 10 minutes.
That prompted a defensive reshuffle and there were yet more changes to the R's back-line in the final moments, when Damion Stewart was stretchered off and replaced by Kieran Lee.
