not really i ran the 3.5 geared at a 9.42 fdr and it came off the track after 6 minutes around 150 degrees
Austin was running lower than 8.0 fdr on 6 cells with a 4.5. You need to gear up a ton. I ran a 7.5 fdr on lipo with a 5.5 and nothing got too hot. We were both crap your pants fast at SS Speedway.
