And after all of that I flew it again last weekend (nervously hoping it wan't going to trip. and the motor would stay in) and it is awesome. I have taken the prop back to a 12 x 7 to avoid too much current drain (and heat -- it still sits at about 900 watts). Neither battery of motor came out of test flights overly hot/warm respectively.

It now takes a little more out the batteries but still looks good for 10-12 minute aerobatic flight. And with a battery cost of around US$240 for a 3s and 4s 3,100 I can live with it.

Now I am through the building and first pass sorting I look forward to getting back to the field and setting about trimming it properly. Will update as I get more experience with it. At this stage it looks like it will fill the bill very well for our local field!
