Reventon R and S have poor reverse. It either actually doesn't work at all, or has a delay.

I like the smoothness of the esc but the problems listed are making me seriously consider selling all my Speed Passion equipment and buying another brand as my racing enjoyment is being spoiled. I would like the SP advisor Solara on this thread to advise on these in case I can make some improvements.
