Ran the 17.5 w/6 cell in TC today, medium sized outdoor track 100x50. Geared at 4.0 and temped out in the 130*s, outside temp was mid 60s. Car was just a hair slower down the straight than the fastest brushed guy (lipo). Infield speed was good. I'm guessing that if I geared at 3.9, they would be very close. Over all I'm very satisfied w/the 17.5's performance, you guys won't be dissapointed
