Mike,

I have will have my camera with me today. If I can stop by my Dad's after work I will snap a few detail pictures. He made a removable chin cowl from balsa. Then he strengthend it with Fiberglass mat (available at home depot, about 2 Oz wide weave great in two layers to strengthen curves -- 3 to 4 if your making just a fiberglass cowl). He used hardwood tabs on the firewall for the #2 button head screws.

If your interested in shaping and making a cowl out of fiberglass, its pretty easy and there are a couple of methods.

and installed on the plane (left-overs reassembled -- but easy enough for a 6 year old to fly)
