Stab for Spitfire

Postby NYKiter » Thu Dec 10, 2020 3:57 am

Added some roll stability to the zeeko with an Fone stab....this shim was 3D printed with a carbon fiber filament. Surprisingly strong.

Here are some images.

Sorry. See above. It will probably breach but will have to see.

I'm not sure I get it, If that F-one stab is curving up like that in its previous life as a stab, that means it is profiled to create a downward force. Shouldn't you then bolt it the other way around for positive lift, i.e. tips curving down? I understand that through massive shimming you can possibly make it generate some lift the way you want, but wouldn't it be better to use it so that the profile is working the way it was designed for? That would also mitigate your breaching concerns!

I think your right. :anonym:

This is always confusing....especially on a canard... good thing I had a nice sesh before trashing myself on the zeeko...

I will make another one and try it the other way

I think the stabiliser is oriented for seaweed scything, just needs a bit more sharpening. :thumb:
