I had a chance to run my rx8 1550kv system this weekend at a club race and all I can say is wow. It is ultra smooth (no cogging whatsoever) and very powerful. The 1550 had more power than my Neu 1515 2.5d. I had to gear the tekin down two teeth to make it equilvalent. The system ran cool and no issues.

bottomline, the rx8 has definitely raised the bar for all the other manufacturers.
