Darren Duffield wins the 15th annual Leyburn Sprints

The Leyburn Sprints have been running now for the last 14 years, the event celebrates the running of the first Grand Prix in Queensland some 60 years ago. This year was one of the best events to date and with one of the largest recorded spectator crowds the organizers and officials must be congratulated and should be proud of the event, with proceeds going back into the next event to make it even better. The other beneficiaries of the proceeds are the local Leyburn community projects like the Rural Fire Brigade, the Leyburn State School P &C and the Leyburn RSL just to name a few.

There were 190 competitors all ready to attack the 1.1Km track around the houses in Leyburn, they ranged from a 1930 Ford A Model Indy Special, a 1999 Porsche GT3, 2 Mitsubishi Lancer EVO 9’s just to list a few cars and only one Rotary Hillclimb Racing Car of Darren Duffield (RPV 01)

Hillclimb Results Round 5

TIGHE CAMS HILLCLIMB, ROUND 5, Sunday, 9th August 09.

It was another beautiful day at Mt Cotton for this round 5 with the weather warm and ideal for some fast times on the track and with only 73 competitors this round we were expecting about 6 runs.

Alan McConnell and Rod Johns were impressive once again with sub 40 second runs. Warwick Hutchinson in his RPV02 came tantalizingly close to doing a sub 40 time with a time of 40.09 seconds. Darren Duffield in his RPV01 not far behind with a time of 41.02.

Fixing Brake issues and reworking uprights on the rotary hillclimb racing car.

We have been running the new rotary hillclimb racing car for 4 months now and during this time the car has performed very well with only a few small teething problems.

It is competitive but the braking system has not been very consistent, and it is hard to drive the car to the max when I do not have confidence in the brakes.  The front brakes keep locking with the bias all the way to the rear, so we have changed the size of the rear master cylinder to 5/8” from 3/4” to get more rear bias but the front wheels keep locking under hard braking.
