Dear Patrick,

I'm just a new comer in DLG.
Need advice from your fellow masters indeed.

For the German Slingshot, you may refer to the following web site:

http://www.handlaunchglider.de/

Slingshot is using the AG45/47 airfoil developed by Dr. Mark Drela. This is a very thin airfoil with flat bottom.

Rgds,
Alan Chan

No, no, no, no, Alan, I don't think they agree the word 'master', we are all just new on that, specially me, I even cannot fly good, you will see next time when you see me fly a plane :wink: :wink: :wink:
As I know, that Mr drela, he designed to use AG47 & 45, but it has a AG46 in between and that is one of the difficult parts to build,
I've spent 2 weeks time to sort it out.
According to your picture, your slingshot is ready to fly, right? when and where you will have a trail, I hope I can go with you n Y.C. :lol:
Patrick
