    Without choke it cannot be started by hand. the carburetor has to be flooded until it makes a smacking noise, then it starts immediately. I own and fly this engine since three years.

    Is it a bought off the shelf engine or home built? The prop shapes are due to the “Rolling” shutter of the camera sensor, where the pixel rows are read out in sequence, unlike a more expensive design that uses a “Global” shutter where all pixels are read out simultaneously. Thanks for sharing very nice engine. Greetings from Tasmania Australia.🇦🇺🦘👍

    • @davidmulcahy4864
      @davidmulcahy4864  Před rokem +2

      Off the shelf from UMS they so a range of 7 and 9 Cyl engines. Nice to see someone who understands global shutter - hard to do with CMOS sensors but can be done. Simple to do with CCD sensors as they have masked off storage areas - a bit like winding on film - CCDs used to be more sensitive than MOS years ago but MOS sensors had billions of deveopment money thrown at them for mobile phones. I spent my life in imaging :). Was UK CCTV prodoct manager for Bosch before I retired. Just saw 4K introduced into CCTV :).

      @@davidmulcahy4864 I have a medical background but also scientific/medical/forensic imaging one, but where the read-out is important for me in in my astrophotography where it makes a big difference when imaging the sun, moon and planets. Started with film in the early 60's to the present day and have too many cameras, both film, CCD & CMOS. Impossible to keep up with the newer developments in digital hardware now unless one has very deep pockets. Also been into R/C aircraft from valve radio Tx & Rx days. Done a lot of climate study, carrying cameras & recording gear up to 1.3km high with a 10' wingspan R/C-and Tx the data to a ground station. Used to be the chief flying instructor in R/C for Tasmania, Australia. Too many interests!! Clear skies, Shevill. Southern Cross Observatory Tasmania 42 South.
