Not to take away from the exciting achievement, but I always found comments like this kindof unusual. Really, it exceeded even your _most optimistic_ simulations? If the high end of your simulated performance was below what you actually measured, I am worried that your simulation is seriously neglecting something. I used to work in decent depth with three phase bldc motors, so I feel I can say with some authority that these things _can_ be simulated, and while real world data is hard to exactly predict, getting something outside of the predicted range would generally be interpreted as a sign that your simulation isn't so good. But maybe this is just marketing-speak, and their simulations are actually totally fine.

Short-term peak ratings for electric motors are always huge. You can put in higher voltages up to arc-over. More interesting is sustained output. 1 minute, 10 minutes, 1 hour, continuous duty. That's all about how well it can get rid of heat.

That's why electric motors have a "temperature rise" number on the data plate. That's the steady-state temperature increase from a cold start when run continuously at rated power.

A typical Rotax 912 with accessories goes over 55 kg for 80 HP max and ~ 60 HP cruise. The 100 HP/75 HP version is around 65 kg. The same continuous power with this technology looks like a 5 kg motor and 60 kg of batteries for a direct replacement, if we consider the regular fuel tanks of 50-100 kg on some planes (I used to fly a plane that took 140 liters of fuel with a 100 HP Rotax, but it was modified) then there is enough battery for a flight school needs.
