Man of Honour
I hate to be a party pooper but I think you should remove the references to altitude. You should not legally be over 400feet indicated with Any RC aircraft.
All of you should read up on this http://www.fpvuk.org/fpv-law/
It's very important as the legal aspects of this hobby will become more and more relevant and you really want to be on the right side of the law.
Coming from a full sized aviation background, do not underestimate the potential for these things to cause damage to full sized aircraft regardless of what that tool Trappy from Team Black Sheep says - if you've ever seen the mess that a bird does to an aircraft then you'd have second thoughts about taking risks.
Just as an example - I've seen the hole (about the size of a football) in the side of a fighter plane after a bird got ingested, made it's way through the engine and got thrown out the side of the fuselage. Having a quad or a foamy which is significantly more solid than a bird, contains a highly flammable/explosive LiPo on board at an altitude that 'could' potentially end up in a flightpath is not a place where any of you want to be.
Please be careful guys, TBS is NOT an example of where you want to be at with your FPV.
I know about the 400ft limit, but is the law above sea level or the land below ?, makes a lot of difference.
If above sea level I wasn't far over, and I couldn't confirm this until I got down and read the altimeter.
The weird thing is though, the 400ft limit means nothing when you see low flying small aircraft buzzing around at what looks like below that ?
