Isacco Heliogyre

Use it to scare trainee pilots into trying harder?

“Top 1/3 go to F2B

Middle 2/3 will be trained for Boulton Paul Overstrand and Sidestrand

Bottom third get to fly this.”

Doesn’t anyone know? I can hardly believe that on this forum!

..From the SARO Putnam volume.

Martin, where do you find them. Whatever search engine you’re using, I’ll have one too – please!

The “RAF” version had four Bristol Cherubs and an AS Genet, again driving four blade airscrews. It was built by SARO and tested in the Balloon hangar at Farnborough…damaged beyond repair. Fortunately? Photo and gen in Air Brit K files.

As one of those deprived so and sos who don’t have access to the AB monograph, can someone post or direct me to a photo of K1171?

At least two of the Bristol Cherub engines found good homes in Buckinghamshire with the Halton Aeroplane Club, where they provided the motive power for at least one of C H Latimer Needham’s, Halton HAC, light aircraft.

Sorry. Please put it down to the time of the post. The serial is actually K1171. Whatever the Isacco Heliogyre was, according to ‘British Military Aircraft Serials 1911-1979’ it was in use from 6 January 1930 to 31 December 1931.

Probably not relevant but the 504 comment reminded me about Ciervas early experiments using 504 fuse.
This link may be of interest, there are some good pics

The serial you quote comes in a batch of cancelled Avro 504K’s and does not appear as a single entry in the Air Brit “J” register.
