[RCSE] Kevlar leading ledges

[aneil]

Hi there, I've been making some Kahu DGL wings http://www.charlesriverrc.org/articles/kahudlg/chriskaiser_kahudlg.htm I've been using 1oz Kevlar and a 1.7oz (1inch) leading edge. I'd like to know if anybody out there has any insight on how to get prefect leading edges so they don't need any sanding (which you can't) after vacuum bagging? How do you get the leading edge to stop pinching under vacuum I guess the guys at Mapleleaf know how to do this, wana' share some secrets with us. Regards from DownUnder Aneil Patel.
