my V2 good after 40 minutes driving 4x cell, medusa 2000kv geared for 40mph...but do expect it to blow
funny thing is my Novak HV 6.5 lasted 5 minutes before it blew the capacitor and now back with Novak for warranty repair and dont have much luck with Novak as I got a GTB a few yrs ago and it blew to..sort of opposite for me
