Hi Don, One thing to consider and I've read a lot of stuff off the net on this:
Adding fowler flaps or any other stall reducing device on a KR will also require a bigger elevator to keep the aircraft trimmed level under these different situations. Just something to keep in mind.

I have been drying to find some information on what is importent in the design but all I can find on the subgect applies only to "Slotted Flaps". I know what LE slots do to lower the stall speed but they also give a nose high attitude that can be objectionable and maybe worse but can fid nothing that helps give a design with predictable results. The 1/4 scale wing wounly be about 22-1/2 inches long with a 12 inch chord but have know clue as to what scale effect might be. I guess that is why NASA has tunnel big enough to put an entire F-18 in as I witnessed when I worked for them in '91. I am not all that knowledgable, perhaps enough to be dangerous but willing to recognise that 50% of smart is knowing that you are ignorant so I do make stupid sounding statements sometimes and often ask the wrong questions. don _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to [email protected] please see other KRnet info at http://www.krnet.org/info.html ----------------------------------------------------------------------------------------- This e-mail is confidential and is for the addressee only.
