The GT V2.1 EX was recognized and looked all the world like a Hobbywing esc. I flashed the V3_508_no_timing software to the ESC then set all of my 1s parameters. Now the Hobbywing programmer works (and it would have before flashing software) just like the Speed Passion ESC is a Hobbywing (and it probably is). Nice 1s esc for about $65.
Awesome. That ESC is still a beast. Many guys are or were running it before the Reventon 1.1 EX came out.
