Instrument panel that was included in the kit was already cut and drilled for a lot of small instruments. My idea has been to use a GlassCockpit, radio and transponder. And a minimum of switches. I bought a 1 mm 6061-T6 AL plate and cut it to fit my aircraft. I removed the ventilator brackets, 6-B-20-57 from underside controlpanel. Those are now a part of instrument panel.
