Tekin RS (Pro) all the way!
In the course of last year, I've tried various LRP and SP speedos, and the Tekin RS. If you are looking for a low(er) priced ESC that is reverse-capable, go for the SP GT 2.0 LPF or the Hobbywing/Xerun/Whatever version, you should not be disappointed. If you want a reversing, small, user-friendly competition ESC, get a Tekin. The LRPs are also nice, but do not reverse. I haven't tried their new PC interface, but I doubt it can keep up with the Tekin Hotwire.
I can't say anything about Novak today, as I stopped using them after frying two brushed speedos without any apparent reason (410 M1C and Rooster)...
Reverse is such a complete waste on a ESC.
I can't wait to try the Kinetic. Now I just need to decide if it goes in my B4.1 or the new to me Schumacher SX2.
