well anywhere i place the tank there is no any movement for the turret. everything just works only the turet movement, i test the motor alone and it'working, i check the 8 pin conector and connection betwen the board it's fine.....check the wire no broken wire from the connector from board to the turret, one of the ressistor does have burn marks but it's still working when i tested it with the electro tester( you know the tester which have meter and red and black cable i do not know the english word) well if the transmiter from the controler than it would not make the turning sound from the speaker. but tonight i'm going to replace the resistor and try it out again maybe tommorow i will post the pic of my board......anyody from this information knows anything, it would be great if somebody has this expirience ........thanks for the concerne.
