Topic: ARD2 tail fin gunship

Fitted a tail fin today which works surprisingly well for straight line stability.

Check out the pics.

Looks very cool!
Is there interference in turning with this fin mounted? (straight forward should be great  big_smile )

Cheers!

Re: ARD2 tail fin gunship

I've just come back from a test flight in quite windy conditions (with and without the weapon packs):

- straight line stability is massively improved, at both high and medium air speeds.
- at low speed, and hovering, the fin acts as a sail, catches the wind and drifts a bit, but it doesn't spin, presumably because the wind is acting on the front and rear of the drone. This would be lessened if it wasn't so windy.
- the weapon packs don't make much difference to overall performance, although straight line speed seems a little reduced, probably extra drag.

I'm going to make a different fin configuration, with a smaller one underneath, and one mounted on top too. The key I think is total surface area of the vertical fin surface - it needs to be roughly the same as the front overhang of the drone.

Thanks TonyTHT for the update.

Have fun tinkering with the fin.

Cheers
