In what case do you think i need to buy a new FET ( ESC ) coz im scared . maybe i need to buy 1 and its too expensive. My car spins its direction of wheel it self . like the steering (on the car ) goes left and right if i go full gas 2 meter away from me. DO I REALLY NEED TO BUT NEW FET!!! IM SCAREDD!!!
check your antenna first.
I dun think your FET got problem.
Or use motor draw less current to see the problem fix or not.
may be insufficient power output only.
If you have soldering skills you may want to add an additional capacitor to the motor. A third one across the motor terminal may help. You can also try to relocate the antenna connection on the PC Board. You can find tips on relocating antenna connection on Drac\'s site http://draconious.net/
