Simple and gets the job done. Some potential questions answered: Yes, it will degrade your axe for each block mined; Yes, it has a range limit (it will stop mining if you go too far away); I think it only allows one at a time (but not sure I remember about that one).
Building it was pretty straightforward, and creating a little runway was fun. The controls are pretty good, though a little cryptic; I suspect there's some flight-y jargon that I'm very unaware of that it implements (I've not done anything more realistic than GTA!). I played only with a multiplayer server with relatively low ping but noticed a lot of jerkiness. The flights are quite fun and relatively smooth.
The gauges are a little perplexing to me and could be improved. The repair tool also should probably be renamed to "Trike repair tool" so that it's not confused as a general-purpose repair tool.
I've been aware of Minetest for many years, but only just recently started playing. This was the game of choice for a small five-person server and we've had a blast. Even though it's a big pile of mods, and some of them we don't like, it's a great introductory experience for us to see what's out there.
We've played for several hours and have resorted to installing two other mods: anvil and travelnet. We all hate weapon degradation and found anvil to be a good compromise. We also hated how it took many minutes to go down ladders to Minetest's 4096 resource-dense level.
Eventually we'll probably adapt our world with other mods but this has been a great way to just play. Thanks to the maintainer(s)!
Simple, straightforward, and speedy. Would be nice to be able to see out of the sides but perhaps it's to hide jankiness from the speed.
I'm not sure about the advertized 990 Km/h, though... It took me about 6 seconds to go 250 meters and 16 to go 400. I also would love configurable speeds. But overall really solid and with nice textures.
