We did test that at the time but it was so long ago that I cant recall the figures. I think the 27 turn was somewhere in the ballpark. If you can even find a 27 turn brushed motor now anyway?

In our experience, once everyone found out that the Hobbywing was able to be used (and was only $120 AUD for the complete system!) pretty much 99% of people changed within a few weeks, no-one ever run brushed motors again.
