I would say dont bother getting the X8 unless you need to carry heavier cameras. But at dronetrest we all prefer to go for the DIY drone solution. We recently build a drone based off our U580 frame which has a max flight time of around 30min with no payload. But the great thing is that it can also carry cameras up to 1Kg (with less flight time of around 15-20min) so its a flexable option. You can read more about the parts in the topic below, and it also works out cheaper than storm drone. If you have any questions just let me know.
