Brief History
This is one of two Hall-Scott Aircraft Engines, 1918, in MOTAT's collection.
In early 1918 the New Zealand Flying School ordered two Hall-Scott A-7A 100 HP engine
s from the United States. One was used in their “A” flying boat to replace the existing Roberts engine. The “A” Flying boat was designed by Leo Walsh and built by the Walsh Brothers with help from woodworkers (including boat-builders) in 1916.
‘A’ was a larger version of the Curtiss flying boats they had. The Roberts engine was started by a man standing on the seat and turning a crank handle which came out of the front of the radiator. Damaged occurred to the Roberts engine in November 1917 and it was replaced by the Hall-Scott A-7A in the early months of 1918. The Hall-Scott had a self-starter and did not need to be cranked.
An enormous improvement was found in the aircraft’s performance. George Bolt noted in his diary for 19 May 1918 “I’ve just flown “A” with her new engine and she’s just a peach! She carried four of us up to town, and with two aboard romps out of the water. She’ll fly at half throttle and her self-starter saves a lot of cranking.”
