2 were early aircraft designed by John McCurdy and Frederick W. "Casey" Baldwin, under the guidance of Alexander Graham Bell for the Canadian Aerodrome Company.

The aircraft were constructed at Bell's laboratory at Beinn Bhreagh, Baddeck, Nova Scotia using local labour.

The only main changes initially involved fitting a more powerful engine and reconfiguring the radiator to provide lift.

A distance of 100 metres was achieved but engine problems resulted in curtailing further flights that day.

[2] After being repaired, and with new coil springs on the undercarriage, the installation of "between-the-wings" ailerons, an added biplane tail and the cambered front elevators replaced by flat ones, the aircraft continued to fly in a series of proving flights at Bentick Farm in Baddeck.

2 was towed up the Baddeck River from Beinn Bhreagh to the Bentick Farm testing grounds.

1 repaired, McCurdy made its first post-repair flight of 90 meters off the ice on Baddeck Bay.

2 was flown over Baddeck Bay, with McCurdy at the controls and on 18 March 1910, with a single float mounted under the center section and stabilizing floats on the ends of the lower wings fitted, the aircraft carried out a trial water landing at Baddeck Bay.

Although McCurdy was drenched, the engine and wings remained undamaged, and the test was considered a success, the first seaplane flight in Canada.
