The weight makes you go mental, and the drag is detrimental, as long it is not
dental....then it is just a drag.

The penalty of added weight is incremental while the savings of aerodynamics is

If I don't mis remember, the ads in different magazines out for the very first

tailwheel. It never caught on though, but's gotta do something.

I think it is a matter of things that adds up.

.....the position lights that is not too aerodynamic, the little antenna, the
little temp probe sticking out, the exhaust pipe that sticks out excessively,
the not so flush tanklid, those unsealed gaps, the naked tailwheel, and so

Each one of them doesn't amount to much, but it's like added on weight on the
aircraft,.... it ads up quick.

I think the drag of the "aftermarket tail wheel" is less important than
having an airplane you can control on the ground. Also, the tailwheel
hangs in the disturbed air coming off the slip-steam and fuselage, so
perhaps less increase in drag than what showed in this video

However, there could be other solutions. A fairing on the tailwheel? I
remember seeing a D-fly with a fairing on the tailwheel. The owner said
he couldn't tell any difference in climb or cruise, however it was a
very small tailwheel. I don't remember who had that plane.

Nice one Sam,

That certainly puts drag into perspective.

Looks those aftermarket tails wheels that hang down are a high drag item.

Merry Christmas all.
