What are the RC stuffs least affected by GST?

Which of the items have the least GST rates?

Thanks 

Because all RC hobby members are loyal to their motherland... and was giving already huge taxes... So no extra burden...
GST is affecting tax hiding tactics...
Moreover some items already manufactured with Excise duty, and sold with GST (incl. Excise duty), so double taxation till stock..
So, expect cost reduction in future...

Thank you for your response, but I wanted some real numbers/data for the stuffs....

I wish if some LHS or sellers could help me with that. I would really be grateful to that.
