How about a Cub only Forum? I see stuff about Cub posted all over this site and thought this would bring it all together.

Probably too specific right now. What we are working on though is a tool to get all like manufacturer or type of planes in an easy link format so you can find them not only with search but through other methods easily. The beginning of this is the product linking tool which lets you link a new thread to a specific product it is associated with.

How about it as a sub forum of scale?

place a poll in scale and see what the other members think. I would like to see a majority of votes in favor of before making a single design specific forum. that is fairly narrow in topic so I'd leave it up to what most members want.

I did as you asked. I placed it in the scale forum and received a few votes, it has dropped down off the first page now. Looks like those the voted are leaning toward wanting it.
