Without reading through the whole thread, what weight range is acceptable? Also, CG is right in front of the holes on the bottom, right? Tested the power system tonight. With a 'right out of the box' battery, I got 408 watts at 30 amps, 13.6 volts.

Don't worry about weight .... she will carry weight OK ... the canopy / battery area will make sure you don't over do it !

Balance point is spec'd for middle of finger holes ... but note that deltas are particularly bad if CoG is back even just a little bit ... so many err on safe side of forward half of finger holes ... some even to the front edge of them. As I say - do not go rear of mid hole !!

I have found the above advice to be spot on, exactly correct. Thumbs up.

Thanks. I re-balanced to the front of the holes. Now weighing in at 415.4g (14.8oz). Unfortunately a friend was having a look and dropped it (broke off the stabs) so it's back to the paint shop. On a positive note, my power system looks promising. With an APC 5x5 i'm getting 540 watts at 36 amps, 14.1 volts. Not sure if it will be as fast as yours though.
