The Scorpion 1400 used to be the most powerful, properly sized motor for the Trex 500... but the KDE / Neu 1708H /1Y has topped it.

The Neu 1905H is strong too (stronger than the Scorpion 1400) but it's not really the proper size for a Trex 500 as it requires you cut the bottom frame away for clearance.

Some testing of the 1708/1Y here, but keep in mind he's running on 8S and Neu doesn't recommend the motor for that kind of RPM.
