Team boss Alun Rossiter declared himself content as Swindon progressed in the Knockout Cup despite a 51-39 second-leg loss at Rye House.
The CFS Filtration Robins went into the clash 28 points to the good after a power-packed display at home on Monday and qualified with four heats to spare, winning 98-82 on aggregate.
Their dominance was briefly threatened during the adjustment to a slick track that contributed to an on-the-night deficit of 12 points after five heats.
A couple of shared races steadied the ship before Adam Ellis picked up Swindon’s first chequered flag in the eighth, dominating the first turn with Zach Wajtknecht in support.
Racing improved as the night went on with Troy Batchelor’s heat-10 victory enough to close in on qualification despite Chris Harris passing David Bellego for second.
Ellis saw off immense pressure from Scott Nicholls to seal the deal and his second race win in the 11th, while top scorer Batchelor rounded off his night with three straight victories.
“We started slowly but the track was very slick. I have probably never seen it that slick and we had to adapt,” said Rossiter.
“It took a while to get the right set-up but we were comfortable enough from there. We know what to expect next time
“Everyone got stuck in and saw it through which was all we wanted, that and to avoid injuries. We knew what we had to do.
“Troy was on the money, David worked hard and Zach had a strong night but I was happy enough all round.”
