Rob Haines replied to Adam Kimberlin's discussion Ducted Fan Design: Is It Worth It?
"I gave this ago a couple of months back mainly to protect the props but i didnt research the science behind it all. It's a 30cm duct to fit a 12" prop. It was U shaped to begin with but locked itself on to the mould. Had to trim it in to a J and had…"

"Carbon has high tensile strength but it's very brittle and cannot take much in the way of shock and would catastrophically fail. Adding a core such as closed cell foam would make it too thick. Adding a core like soric defeats the object of least…"

"Martin, very nice carbon frames. I was looking at making something myself but have been tied up with other things,

Any idea on the composite…"

"That kind of sounds like what im working on a the moment. Its a 34mm ID duct 50mm deep.
