Trigger74,
You have the same model I started with.
If you use Cobra's kit you won't have to do any scratch buiding. Here ( http://www.aircraftresourcecenter.com/Gal-Fea%20Archives/helicopters/MH-6/MH-6.htm ) you can find gallerys of two MH-6 build with Cobra's kit.
I didn't use Cobra Company's kit for several reasons:
1. It's hard to find here in Italy
2. The planks didn't look like the ones I saw on the pics I found o the net.
3. I don't like how some of the parts are made.
So I had to do a LOT of scratch-building starting off from the planks ending with the antennae. If you have a look here ( http://album.foto.virgilio.it/klaus_models/301984 ) you can see some pics of my model before painting. All the white parts are built from scratch (mainly using plasticard).
Hope this helps.
