Hi Utera, don't be sad, hyng said "Please don't simply upload the photo
without further explanation". Not means you can't attached more pictures. From my view, you just need a motor and motor driver. Cytron have sold many types of driver motor so you can choose it. About the heat resistance, maybe you can put the electronic circuit far from the muffler (Heating source). Sorry can't help much, I'm not mechanical student.
Request for complete solution for FYP? Why don't request for graduation certificate?
