jazza the Academy Cobra kit builds very well. No flash or fit problems, and very minor sink holes which are easy to putty and sand. Cobra Company has a resin kit out to up-date it,
http://www.cobracompany.com/35009.htm Twobobs had a nice set of decals out, "Whiskey in the mix" they are no longer in stock. Good news though, Twobobs and Fireball Model works are planning releasing new sheets after the holidays.
As for the knobs, simply done by sharpening a tooth pick using sandpaper, then dab the paint on to the raised knobs. Just keep wiping of the paint from the tooth pick, doing so helps so that paint dots don't become large.
As for the smaller knobs and dials well...after I sprayed on my flat black and once it dried, I too my hobby knife and taking my time, I scratched of the black paint from the knobs and in the dials. Simply enough right.
Thanks guys and oh yeah, Elad it will be a OIF helicopter.
