The spektrum is a rebranded savöx pretty much yeah.
I got the became on order, its coming from new Hampshire to here(Arizona) so it'll probably be next week b4 I can drivey wraith again :/ at least my exo and honcho are still good to go lol.
However what's weird is that my exo has a hobbywing sc8 ESC, a spektrum avc receiver, and a savöx 1256tg servo and it doesn't brown out.
Those 2 servos are very similar.
