Just a quick question, are hpi flux pro motors star wind or delta wind, the reason i ask is will they run on a lrp sxx v2 speedo, all wired up and set up as per instructions, but, when the boost is set to 5 or above it starts to stutter and the revs fluctuate, it has good quality wiring and the sensor lead is new and the motor has only been run for 5 mins
