Hi Danny - will be glad to help with any questions, it's funny because I was only looking at the plans last weekend, I'm toying with the idea of scaling it up to about 80" span (in the future!!)
I seem to remember an issue with the aileron's, bear in mind I built it in 2008/09 so a distant memory. I also did away with the top forward hatch, access is from the bottom wing opening.
Hi John - not sure on the weight, but she fly's very scale like on the 120. And sounds good too!!
Richard
