I hit 65.7 MPH today with a 1515 1.5 on 5000 mah 6S. 23/62 gearing. I would have had a video of it, but my buddy thought my camera was rolling when it actually wasn't. I do have a 62.5 MPH run on video that I may post soon.
Blew out my HPI Phaltlines - well one at least. They glue those on top of the "chrome". Lousy.
Anyone hit a higher top speed than this? I think I could hit 70 or close to 80 with the right gearing. I could tell that gearing was the limiting factor.
Heat was no issue at all. After multiple speed runs and 15 minuets of hardcore bashing, my motor temp was 151 and my MMM V3 was 155. Awesome set up to say the least. I'm glad I went with the 1.5 instead of the 1Y now. It had plenty of torque on tap, even while geared on the high end.
