I agree, I have a Quark 33 pro in my inferno with a hacker and it rips. Email Frank@Quark.com and tell him what you are doing and he will recommend the best esc and hacker motor for you. He knows about this stuff, he just won the 18th scale National event with this setup.

I had a Mamba that I had terrible cogging problems with to the point that I gave it away because I was so dissapointed in it. That is how I came across the Quark, and I have had no problems with it what so ever.:027:

As for the article, be aware that although the review of the Quark controllers were favorable, the pricing on them was mentioned as too high. This was a misprint on the magazines side. They had wrong prices listed for some of the controllers which made them seem like they were overpriced compared to their competition, when in fact in some cases they were less.
