4 / 8 channel current sensing

[GoogleCodeExporter]

Current sensing on every single ESC could be implemented, to get diagnostic 
information about electric motor-propeller-performance. When a propeller breaks 
or falls off, or a motor winding is damaged or an ESC breaks down, lifting 
force misses.
As the pilot or the flight control cannot react that fast, the copter can be 
lost (my experience last weekend).

My interest would be a 8-channel (or dual 4-channel) current monitor; i could 
design the PCB. 2 NXP I2C ananlog converters and INA138 current monitors, 
assembled on a center Power-Supply-Plate between battery and ESCs should do.

Three questions, if you are interested, please give me a feedback:
Is there a need for diagnostics on motors?
Does the Copter software concept offer calculations on single-engine-level 
(power, rpm, thrust,...)?
Is there anyone interested to impelement a monitoring/warning/safety-concept on 
engine action?
