Hobby Lobby used to publish thrust figures with their electric ducted fan units. I was just on their site and noticed that they no longer do so. Kress jets does, but I'm looking for something smaller and possibly less expensive.
Are there any good resources for finding the thrusts of various fan/motor combinations so you can order parts and know they'll work _before_ you have them in hand? I know there are a kazillion variables at work here, but it'd be nice to have _some_ guidance!
