Also, please note that your supplied wood cowl mounting brackets are NOT the correct shape. They have way too big a radius to fit the shape of the cowl. This is easy to fix. Just hold them up to the front ring after you have it fit to the cowl, draw a line on them and shape them to fit the new curve. They will now fit perfectly.
The Omnipotent CARF strikes again. And they will never admit it. Add this to incorrect embossing, the miss shaped tail gear door area, the incorrect rudder shape, the lack of any indication that this aircraft actually did have wing guns, the completely ridiculous hydraulic wing system, well, I could go on, but it is what it is, still a great plane.
