Ago C.IV

The Ago C.IV is instantly recognizable by its sharply tapered wings. While aerodynmically efficient (as hundreds of WWII designs proved), it made the C.IV difficult to manufacture. Their crews found them difficult to fly and with limited climbing capability, which is surprising given their excellent Benz engine.

The addition of double ailerons, a curved fin, and extra wing bracing improved its handling, but by that time there were much better two-seaters available.
