I just thought you'd had a beer or two Alan
(Note: I am only joking here. I am not in any way suggesting that you like to drink or that you have a drink problem - or that anyone else in the world has a drink problem, or that having a drink is any kind of problem anyway. But if I offended you, or anyone else, it was completely unintended and I apologise in advance)
Anyway: I just got through drilling-out the V-7's needle-valve. What a tiny hole it is! I could get a .8 mm drill shank to go through the original hole ok, but .85 mm was "just" too big. I decided to drill it out to .9 mm and will report back after next week's flight tests. Thanks again for your help on this one
