It’s been over a year & still not completed!
There’s many many design choices to be made. For instance the main power switch, surface mounting connectors, battery mounting. You could do a workable unit in a few weeks but to build a high spec x4 with great attention to detail & safety will take a long long time. At the moment it’s taking me ages just to enlarge 4 holes in the back plate for grommets to protect the props, but I could have just bought some prop covers. The kit could be made a lot easier: for instance more 3D parts included, aforementioned holes cut bigger, better anti-spark switch included (maytech). As it is, the basics are there and it really is an impressive & unique design. If you have a lot of spare time & enjoy the tinkering & the achievement of building it I would recommend the X4. It’s a little lighter in weight than the xp140 & no torque & less money.
