Very, VERY encouraging. I tried an air-to-air test at the weekend using two plastic aeroplanes with bubble canopies, both aerials vertical, but I only managed about a mile and an ARF - so disappointing (and sadly expected) that I didn't bother posting. It looks to me like the new P3I module has a range in excess of ten miles - excellent work, guys!
All of which just leaves one question... when can we order the new board? I'll take two!
