Default slope plans

hi all

just wondering, i want to build a fast and agile slope soarer from plan. it doesn't have to look brilliant, just simplyfly well.

i have already an ASW 28 (3.5m) and gentle lady, but nothing small and cheap - designed to really fly fast on the slope.

can anyone help with some URLs for plans etc. as i am in europe, i don't know of any of the normal usa guys.

any help appreciated.

You might be interested in looking at this information:

[URL]http://www.phoenixmp.com/articles/slope.htm[URL]

It discusses designs of slope soarers.

From the lack of response to your post it appears there are no plans available for download. You might think about scratch building. There are some airfoil coordinates that can be found on the internet. The airfoils can be printed to your printer, cut out, pasted to plywood (for templates) and the ribs can then be cut.

It appears that the airfoil is the most important. Consider some of the airfoils discussed in the URL above. Once you have the wing built it should be rather simple to make a fuselage and tail feathers. Weight does not appear to be a great concern as long as it is appropriate for the wind (or lack thereof) you encounter.

It seemed to me the author of the webpage article leans toward using the Eppler 374 and S-3021 airfoils. These can be downloaded from the internet and sized for your needs.

Thanks for that link Keith! Great reading for the scratch builder.
