Yes, this costed lesser than $300. majority goes to power wheels. Not as strong but i can sit inside and control through window. But R&D costed way more than that. failed and left over parts will be more than working version.
I have failed or stopped version video too. Please check.
It was really fun. I have more ideas to try but not sure when you have working version even its not outstanding. it can invite complaints from my family.
