Does anyone know what the hole in the belly skin in which optional nutplates can be added? I tried the standard radio antenna & the holes don't come close to matching. Is there a different antenna that I don know about?

I think it IS the radio antenna. It is the one that is a long piece of metal with a bend in the middle.

Stan, what do you mean by the "standard" antenna? Do you already have the avionics kit?

The hole is for the com antenna as described in post above. In early kits like mine they were bolted in. This required reaching inside the fuselage with one hand to install the nut. Not impossible, but awkward. The nutplates make installation easier, and eventual replacement, if necessary, more convenient. Not a BIG deal either way.
