Fin-Less Delta Wing Experiment

by schraut5 | May 10, 2012 | (16) Posted in Just Fun

Experimenting how small I can make the fins on my delta wing design, while still maintaining control in the yaw axis. Hope that you enjoy!

The plane that I am using here is a pusher version of my Delta Wing design. All of the same dimensions, except the root chord has been moved up a 1/2 inch and the back has been squared off to accomodate the prop. Flies great!

PDF's for the puller version of this plane, it's exactly the same, just take off 1/2 inch in the back and square it off:http://www.intensewalkera.webspace.virginmedia.com/public/PLANS/SCHRAUT5%20FL...

Wing span: 30 inches
Root chord: 11 inches
Tip chord (including 2 inches of elevon): 9 inches
Sweep: 11 inches

Motor: 1300 kV blue wonder (and 1500 kV)
Prop: 8x4 (1500 kV has a 7x3.5)
ESC: 18A
Receiver: Orange Rx
Battery: 1300 mAh 11.1V 3S lipo
Servos: T-Pro 9 gram

Very, very cool. The whole time I was thinking "NO! He's going to destroy that beautiful plane!!" but it all worked out fine. Would have never known, thank you!

Yeah! I was a bit anxious flying it too. I had no idea what would happen

Good work. interesting vid. Wish I had your talent in construction and deconstruction ;)

Thanks for showing this. I actually wanted to know what would happen without those also.

Man, nice experiment there, thank you so much for posting the list of the parts needed. also I already downloaded the PDF and will be building my own soon.

BTW in one of the recommended videos at the end I saw how you build your airfoil. Loved that video.

Thanks a lot man, really good stuff.

Great job! Very interesting. I tried this with my Swift II and it didn't work that well. Maybe it's because of the airfoil you're using.

I do think that this airfoil adds a lot of stability
