Depends on the machine. Antares has better motor cooling,
but batteries start to get hot and require early shutdown
at Uvalde for example (I typically shut down 800-1000 ft).
Perhaps cooling for enclosed FES motor isn't as good?

See ya, Dave

Pylon mounted motor will obviously cool much more easily than enclosed motor cooled through a small hole. Each concept has it's trade offs.
