Title: Helio AU-24 Stallion

The AU-24 was an enlarged version of the earlier U-10 Courier powered by a turboprop, and first flew in the late 1960’s. It only found one customer with the USAF, it being too expensive for civil operators. 15 armed examples were obtained by the USAF, primarily for SEA operations, and all but one of these were eventually transferred to the Kmer Air Force.

To maximise value, this title contains the USAF Flight Manual for the AU-24 Stallion, and also for the earlier piston-engined U-10 Courier. The files have been scanned from the original flight manuals and retain any colour pages.


This title contains:

  • USAF Flight Manual for the Helio AU-24A Stallion (CCT), T.O. 1U-24(A)A-1 dated 1-3-73, with approx 135 pages.
  • USAF (includes US Army versions) Flight Manual for the Helio U-10A, B, D Courier, 1U-10A-1 dated 15-1-67 revised to 15-2-69, with approx 180 pages.
