Well I have the cockpit done up and ready to install. I have enought PE bits and pieces left over I may use on the Airfix number if I decide to do it as well. As far as the Hasegawa kit there are no internals for the inlets, just a vacant hole so I made some ductwork to fill the voids in the wings. I made them out of plastecine and then made a mold and cast them with smooth on casting resin. A bit of cleaning up but they should fit the part.
In the "why didn't I think of it dept" after sanding and trying to fit my casting. I tried your idea with the shrink tubing. Fortunately I have tons of it in my box. Works like a hot dam and way less brain pain ! Thanks !
