The 480nm number is really impressive at this size. Especially at 5000rpm with the 4-1. Compared to a ICE motor that weighs ~200kg, you effectively free-up 40kwh~80kwh (80 if you believe the 400w/hr claim that Tesla makes) of battery capacity right there. I think there's still a long way to go, but seeing things like this and planes like Pipestrel's electric planes, GA electric planes are more and more feasible.

Absolutely. It's easy to focus on comparing what we are working on with the other (few) electric solutions being built out there, but compared to combustion engines the specific power is a big step change. When you combine that with improved specific energy (either from cutting-edge batteries like what QuantumScape is working on, or cutting-edge fuel cell systems like what HyPoint is working on), you can see the path to GA electric planes and even small business jets is not far off.
