---Later that same year, the 250 Comanche was approved for fitting of Edo floats sporting an 88 inch prop. Apparently this conversion did not become popular, as this is the only known example.
The original PA-24 prototype N2024P, was meanwhile being used to test a variety of engines, including a fuel injected 180 HP along with a 265 HP Lycoming.
Around this time is when Max Conrad made his historic long range flights to promote the Comanche for the Piper Aircraft Company. Max flew a 180 about 7000 miles and a 250 about 7700 miles across the Atlantic. He was well over twice the gross weight of his aircraft. What impresses me, is not so much the distances that Max flew, but the incredible strength of our Comanche airplanes. By the way, the 250 Comanche that Max flew, N110LF, is owned by The Comanche Flyer Foundation, and is on display, with the long range cabin tank installed, at the Liberal Air museum, in Liberal Kansas.
In 1961, Piper began testing a fuel injected 250 HP Lycoming, and it became available as on option later that year.
In 1962, the PA-24 design was improved with the addition of Fowler electric flaps, toe brakes, and the 15 gallon auxiliary tanks were made standard equipment on the 250.
In 1964, the 180 was discontinued, since it had accounted for only 30% of sales since 1958, and it was becoming less popular.
---In 1964, the fuel injected PA-24-260 was introduced.
---The 260-B model came along shortly thereafter.
