Flying Spur filly Avionics put her Thousand Guineas campaign back on track when she responded to a five-day back-up with a victory at Moonee Valley.

The Robbie Griffiths-trained filly led all the way in the Fulton Hogan Pty Ltd Hcp (1600m) after blowing the start in last Saturday's Thousand Guineas Prelude (1400m) and finishing a moderate eighth to Ortensia.

"When she came through that run so well we elected to go for the quick back-up," Griffiths said.

He said he was hoping that Saturday's race might have taken the edge off the filly who has a reputation for overracing.

"We have got a high opinion of her but she has been a bit aggressive in her races," Griffiths said.

"We planned to ride her forward from a good barrier at Caulfield but she slipped at the start when she lost her footing and got back in a slowly-run race."

Drawn the outside of the nine runners, Avionics led for the first time in her career and despite throwing her head about in the middle stages, Peter Mertens was able to get the best out of her to win by a half-length.

Charzoo, who Lee Freedman is also aiming at next month's Thousand Guineas (1600m), finished second, 1-1/2 lengths ahead of Testa Monte.

Griffiths said Avionics still needed to improve to justify her place in the Thousand Guineas but was hopeful she could get there via the Group Two Edward Manifold Stakes (1600m) at Flemington on October 4.

"Physically she looks right and she has the right pedigree to go there but she has got to learn to rest a bit more to go to the top level," Griffiths said.

Meanwhile, one-time Caulfield Guineas prospect Naku Penda emerged as a Carbine Club Stakes contender when he scored a timely win in the Citywide Service Solutions Hcp (1200m).

The David Hayes-trained three-year-old lost momentum going into the spring when he confounded the stable with a lacklustre sixth to Time Thief when resuming over 1000 metres at the Valley on August 27, but impressed with a strong finish to score by 1-1/2 lengths from the talented Tindal with Gold In Dubai a head away third.

"He is a pretty talented horse but he disappointed us a bit first-up," assistant trainer Gary Fennessy said.

"We thought he might have been a Guineas-class horse but he is probably a bit behind now.

"I think he will arrive at the Flemington carnival."

The $250,000 Group Three Carbine Club Stakes (1600m) is at Flemington on November 1 and is a traditional lead-up to the Group Two $400,000 Sandown Guineas (1600m) on November 15.

Naku Penda has won two of his four starts including his debut at the Valley before finishing midfield in the Group Two Pago Pago Stakes at Rosehill at the end of his last campaign.
