Twin-channel ESCs

[mole55]

What are some good twin-channel ESC's for featherweight? (Brushed motors.)

A good twin channel feather ESCs would be a Ragebridge...

Scorpion XL and the larger Sabertooth models also do dual feather sized ESCs, but they're not as bulletproof (or as expensive).

It's rare you need a dual ESC though; most people just use a pair of single channel ones like TZ85s

For the batterydrill machines with 540-550 size motors, the IBF series is good stuff.
Looks a tad low in amps, but those are German Enginering Ampères, not Chinese hobbyamps.
