well ran my prototype ESC this past sunday at a local throphy race, what can I say? qualed 2nd and won the main. the quality is like nothing else I ran tekin prior and the viper takes the cake! I did have to gear way up compared to what I ran prior I had a 88/26 ended up with a 83/30 motor timing at 35, no boost allowed in the 17.5 class
