Well, flashing a config file (from Peabodys old web page) for the brushed sparky seemed to help. There seems to be a default setting that it does not like with my hardware. Will see if I can replicate this sometime.
The radio calibration for the CGS does not work. I was having major freezing and poor UI performance with Mac OS CGS. Windows was better. I actually got this thing flying for a few secs but servos need to be reversed - pretty mundane stuff. Further than I got with Taulabs.
The Peabody voltage and current sensor coefficients are way off. Wonder if this changed subsequently.
All in all it is not a very easy process and I am pretty experienced in such things (though not in these flavors of firmware). That said I am pretty sure this mostly is due to this board. On the RCGroups thread very few people managed to fly this thing. I think it's launch coincided with the transition from Taulabs to dRonin.
Think I need to ditch the Taulink and just get a micro FrSky rx.
Or better still get a Seppuku!
