Guys,

thanks for all of these suggestions. There's some great ideas here, I will have a go at some and see what difference they make. Although it may be for a while, if the current crappy weather continues. OK (just) for flying, but no good for noise testing!

I should point out that it currently meets the FAI limits, it is the UK's DoE limits, which are stricter, that I am trying to meet. I am not expecting any one change to make a huge difference, rather a few small changes that hopefully will add up to a reasonable reduction in noise.

Thanks again to you all,

James
