new novak, no go???

[ozpall]

I just got a new inferno conversion kit, run it about 4 times around my house and it worked good, now at the track i went to race it and no power to motor, the esc lights up like is gonna go when i give it throttle but then i get a blue light and that's it. the manual says that is the overheat shut off for the motor but if i haven't run it how can it be over heated?
please help, i need to get this going for the next race.
thanks.
