Ivan,
Having built an aeroplane I know where you are - thankfully mine was from a set of drawings and did not require the engineering hoops that you've successfuly jumped through!
It is the BAeA national championship that day so if we finish early or I have to throw my towel in, I intend to hotfoot it down to Kemble on Sat evening.
I'd be delighted if you'd care to show me around your creation, Sat eve or Sunday morning!
Well done!!
Stik
