Yes! That's it. Two servos would be enough and we could "sell" it as an option too.
In the data sheet of this current-sense amplifier they even use a PCB trace as Rsense!
"My" data sheet is from 2011

Here is something similar with a Allegro acs756 current sensor

[]Arducopter forum[/url]

HEre you can buy one of this:

Some data about the Allegro - but this is using Hall effect from a near by copper path - sounds like lots of try and error in the board layout?

This one is using a TI INA-169

see here ->

I can source the INA 139 and 169 in a "stupid" all people pharmacy price like shop (Conrad) for 2,24 Euro
The Data Sheet is from 2000 and revised 2005

Can't find the MAX4372T in this shop.

But found a LTC6101BCS5 for 2,59
and a LTC6101AIMS8 for 3,22

In the other German "all people shop" Reichelt I also can't find any of this...
