Dear Sir I do not have any money buy an expensive drone so I bought a Ttr003 hornet, and on the first flight it caught in a tree and stripped the small drive gear, I have tried to get in touch with the manufacturer, with no success and spares seem to be nonexistent, the shaft is only 1mm Itried to find a metal drive with 12teeth and a 1mm shaft. I would be happy if you could suggest something , possibly throwing it out the window or a solution.
