I am no expert at these things, but I have been reading here a while. I think a sustained 50A@24V out of a Piggot 10'machine is going to burn up the stator eventually. Others will likely chime in, but everything I've read says these things are good for 600W continuous, with 1KW peaks acceptable.  

The heat of the rectifiers isn't much of an indication of the heat in the stator.

DanB, Hugh, or Flux  would likely be the final authority on the subject, but it appears like you need the machine to furl earlier, which can sometimes be accomplished by decreasing the weight of the tail.

I don't have details of Hugh's 10 ft machine so I am not in a position to pass comment.

From your pictures you seem to be using the 10 coil 5 phase winding of the type used on the 8ft machine. If so you are pushing it too hard at 50A. The odd peak to 50 wouldn't hurt but if you are in a high wind area I think you will have a short life.

For that winding ( unless it is different from the 8ft one) I don't think you can expect it to sustain more than 600W. With larger blades in a high wind area you will probably get fairly continuous power in the peak region rather than the occasional gust. Try to get it furling earlier.

Nice set up you have there, excellent work.
