    Can't help but wish the great UL-39 team had created a similarly powered, updated version of an RFB Fantrainer or the Fanliner with a 5' or 6' duct. The rate of climb would be terrific.

    This is for all you aspiring Jet Jockeys.

    A very good friend of mine, Josef from the Czech Republic who used to live here in Aus but returned to his homeland about 6 years ago, has been keeping me updated on the progress of the all carbon fibre Ducted Fan Ultralight Jet a group of University people specialising in aviation have been working on for about 10 years and they finally have their Ultralight replica L39 completed and flying.
    Check out the Pics, a brilliant dream come to life!
    This is all the info I have at the moment and as soon as he sends me all the specs I will put them here.

    Cheers,
    Graeme

    It's Malish's single duct bird. Almost exactly. Interesting parallel evolution.

    Pretty thing.

    I thought Malish had dual ducts.

    Beautiful. Nice work! I'd love to see some pictures of the fan if possible.

    Thanks. A little more elegant than my aluminum blade, wood/fg stator test fan. I like it.

    Haven't seen it mentioned so does anyone know what engine is used in the UL-39? Going by the video, it sounds like a very noisy 2 stroke.
