thanks for the info im running 13 pinion with the standard kit spur. the timing on the esc is still at default. i was kinda stressing the timing did not want to turn it up too much the motor temps after a good race are at 145-150 its nearly 100 deg here every day in south louisiana. ill check tonight to see where my timing is at. i thought it was safe with 3s on the 5.5 ill check. my plan is to get one of the new pro4 tekins when they come out i called them today for a release date they said they dont know when yet. i had a novak ballistic 5.5 in my jammin for a year or so on 3s never had any troubles but the lrp scares me i had the 4.5 for two packs and the rotor spun on the shaft thats why it went back ill check with them to see if the 5.5 is 3s safe
