Curtiss Pusher

Ride along with a restored, 1909 Curtiss Pusher aircraft:

The airspeed indicator appears to be an ultralight-style indicator. It shows airspeed from ram air as it moves through the air. Low-tech and very lightweight, but I’d imagine it will impart a small amount of drag. Not nearly as much as, oh, the rest of the aircraft’s rigging would.

Also, the two strings hanging from the trailing edge of the upper canard share maritime term but have a different purpose and position: telltales.

On sailboats, telltales are typically on the face of the sail and help to indicate whether the sail is in need of trimming or adjustment.

On aircraft, they indicate to the pilot whether the aircraft is in a slip. On some aircraft, they’re part of the avionics and are required!

There’s even more about this aircraft here.
