yup...i did put the schottky diode for the motor. I'm using 1N5819 (1 amp) as I can't get the 1N5822 here.
Hi Kwai Weng,
If you are using Mabuchi motor (RK370SD), below is the datasheet link:
http://www.mabuchi-motor.co.jp/cgi-b...AT_ID=rk_370sd
If I'm didn't remember wrongly, GWS300 or GWS350 is using RK370SD.
You can get 1N5822 easily in Sim Ling Tower (Singapore) or you can order through Farnell (Malaysia).
