ESC advice - instant reverse

[LongRat]

I'm looking for an ESC that has instant reverse. As soon as you go through the neutral position and into reverse, the motor must begin to turn backwards. The problem is, it needs to run a sensorless brushless motor and not a brushed. I've been unable to find any ESC that definitely has this feature that wasn't a brushed-only ESC. It's for a skid-steer system (twin track, tank style drive) and there are plenty of tank ESCs about but they are all brushed only. Only needs to be able to sustain about 10 amps or less. If anyone can point me in the direction of such an ESC I would appreciate it!

There are some speedos that do this used by the oval crew, pretty sure there is a hobbywing profile for the hobbywing range too

Thank you Mark, I just took a look at the HW range and the micro 18A sensorless car ESC does have a rockcrawler mode with this feature. I will buy a couple of them. Actually used one in my Mardave for a year or so and handled a 13T ok... pretty solid unit. Shouldn't have sold it I guess.

Old tech brushless novak GTB has instant reverse if I remember right.

Cheers Col, but none of the old Novak stuff will run sensorless. Plus I'm looking for something low power and as light as physically possible (think flying tank).
