I am about to start my new project (1/4 scale Pitts Special) and have a question. Are there any tutorials on how to build a fiberglass cowl? I have built many scale models over my 40+ years in this hobby, but have not yet had to build a fiberglass cowl. I would always build them out of balsa, just like the rest of the model. Any suggestions/advice?

Thank you,

Edwin

I have an article on our clubs web site. This is how I do it.

You should build a lighter than normal cowl. Then just put a correct layer FG cloth over it. Why people glass any long nosed plane is weird. They just create a COG problem. Short nosed planes MAYBE.

Build & finish this plane as usual. See how many ounces you can move around before your COG is.. no good. That weight is your... MAXIMUM... FG covering weight that can be tolerated.

Cowls get the MAXIMUM amount of engine vibration. Ever see cracks ? STAY with wood & paint.
I am a great one to give advice ? I only build in blue foam. [X(]
