Few days ago I bought the drone Syma X8C Venture, very cheap, under 120€. It’s a good initiation drone, but it has a few problems.
This is a typical indoor training flight, transitioning between two landing zones, flying it on all axes and speeds:
But not everything is so beautiful, the cheap engineering and overall quality reulted in a bolt being loose and stricke into the gearbox, causing random engine failures and crashes like these:
No problem to repair it, but now the gearbox is damaged and the drone does not fly so well as before.
