"Larger helicopter with doppler autopilot could be considered as last resort but we will be over built up areas so noise is a big issue as is fitting our camera."
Just curious, in this era of Big Brother and one cctv camera to every 14 members of the population, as to WHY you want to hover over built up areas to take photographs with that level of precision.
I may be being over sensative about the noise issue, but the kit would have to travel to various countries so AS355s would be aircraft of choice due to availability of aircaft and brackets and we could take our own handling pilot. I think using two pilots is a no brainer.
Why do it? There is money in it if we can make it work
We wont be doing council housing estates
