Edmond,
hold off on your purchase for this application, we are working on a new ESC version that will handle the high demands and high heat we have here in Vegas in the 4wd SCT class, I have been running a VTX10R v.2 prototype for quite some time now and have had great success and results with it, we should be seeing the final product hitting the market real soon. I cant say too much about it, but the performance is awesome and will be worth the wait and be very competitive against the others makes out there
