There days brands like Syma, Modelart etc are offering spares for their helis online. But the problem is that fixing these spares on your heli requires technical knowledge. It will be helpful if one takes the spares to a 'RC service center' or 'RC mechanic'.
So I ask- Any RC service centers or mechanics in India?
What does one in India do if his heli does not work anymore? Get a new one?
