Thanks Gents - I think it looks better too. I have to say that whilst it's not the best kit/build in the world I'm really pleased as to how it's come out - I've put off doing these modern (ish) USAF schemes for ages because I thought they wouldn't work out very well with a brush but actually it's okay - more to come. I've started painting up the Tamiya CJ (bays and intake) and will hopefully get some colour on it soon.
Really liking building the Viper though, what a great looking aircraft.
Carlos@ It comes from my years suffering with insomnia, where I'd be up for three days as a push. I could in all honesty start work at midnight quite easily and work through until the small hours. It comes in useful with my son if he has a rough night and I have to sit up with him whilst he's in bed (I sit watching movies on the Kindle) - recently because of him I've not got to bed until 5:30

But usually I try to make myself get to by by 12, and then I'll read for an hour. My wife brought me a Red Light for that purpose.
Cheers!
