Default Novak GTB Problems

Hi, I recently bought a second-hand GTB 5.5 Brushless System and I tried it out for the first time today but it was having these wierd problems. Sometimes the throttle would work, other times it wouldn't and the blue LED would blink suggesting a locked rotor.....but the drivetrain is completely free, the funny thing is that if i give it some throttle and push the car with my foot to get it rolling it actually gets power I have no idea what could be wrong with it....the setups are all ok, but it looks like the previous owner tried running the brushless without a power cap and melted a bit of the plastic on the case, other than that once it gets going it works perfectly fine.

i have a new power cap.....or more like two 10v/4700uF power caps wired in parallel for a dual throttle look and some good cappage performance the motor also sounds like it has some rough cogging in the low revs....not sure if it has anything to do with the locked rotor detection problem or not...
Can anyone help?

what it means is that you have a burnt out mosfet on your speed controller. it does not fire up when the rotor is in a certain position. you need to take it back to novak for service. i had this problem with my first 5.5r system and that is the explanation i got. same exact symptoms as yours.
