    I'd be well tempted to modify the Peggy trike to a shortened monopole - paying due regard to prop clearances. (And 4" is a bit tight - you'd be surprised how much the whole airframe distorts and rear flying wires go slack when one wheel hits a rabbit hole!) An Ivoprop is worse as you need to give lots of room in front of it as it's really flexible.
    I realise modifying the monopole precludes swapping the XL or Q wings though.

    It was a long time ago, I could be wrong, but speaking from memory, Raven had Fuji Robin EC-44-PM engines.
    May be it is this engine that differentiates Raven from Raven X

    Yeah. You could be right. Just couldn't find a TADS for it.

    I will be talking to Roy in a week or two, will ask.
    He lives near Oshkosh. Has a string of patents under his belt.
    Now working on an innovative hovercraft project.
    One of the talented people that the microlight industry and the sport lost, thanks to the Section 'S' bureaucracy.

    I didn't say the inverted 462 wasn't any good! I had installation trouble due to the oil supply for the cross shaft. The small metal pipe that exits the crankcase turns into a u bend when the engine is inverted, thus the oil reservoir only keeps the flexible pipe topped up and not the cross shaft if oil is being lost from the seals anywhere. I couldn't see how to get this little tube out without major surgery so I knocked the project on the head.

    The photo in TADS show the Southdown trike with its characteristic streamlined tank.
    But the manufacturer is given as Medway Microlights. How come?

    One irritation with the inverted installation of either the EC33 or the EC44 Robins was that the oil drains down the ports and wets the plug. Had to remove the plugs at the end of the day.

    for anyone with the "Duopoles" Hybred raven, the job of inspecting the mounting holes is much easier if you drop the wing. On my third inspection I learned that one!

    As a slight aside, I want to restore a damaged raven in my shed and I need a Keel for it. Does anyone know where I could get a good used one?

    You could try AFORS but keel on its own is likely to be difficult to come by.
    Keel is just a tube with holes drilled.
    It is made from HT30TF (old BS1471) cold drawn seamless tube.
    Current equivalent is 6082T6
    Don't know current stockists.
    Will require a piller drilling machine and a V block.
    Once you have sourced the new tube (of the same dia and guage) take it along with the old tube to a machine shop and they will be able to drill it accurately.
    Or you could try Medway, albeit at far higher price.
