I was at the field today between 14:00 & 15:00 all on my own , good flying too. There is a dead sheep along the fence line towards the gate from the pits, I saw the farmer so reported this to her. I hope no one had plans for a BBQ Smile .

Not sure I agree completely with his findings on passing a 2.4GHz signal through trees. It has been scientifically proven that the wavelength of 2.4GHz signals is absorbed rather well by water (it's how the microwaves work in your kitchen). A damp tree, or different types of trees are going to give different results.

The same goes for passing a signal through a human body. It is going to attenuate the signal somewhat, the exact degree of which is rather variable....

Those of you that are interested may find this of use http://www.rcgroups.com/forums/showthread.php?t=1177191
Range tests for various manufacture/rx/tx combinations, the 'park fly' rx's are not that bad especially with the aerial mounted verticaly.
