    Not sure if these are the size you need but easy to make as others have suggested.

    Fisher Flying Products Announces New Electric Propulsion Systems

    An electric trainer with quick swap batteries makes sense for a flight school.Pipistrel Alpha Electro fits that mission. How about an electric helicopter with helipads for charging.

    Lets talk about diesels.

    Another opposed piston diesel is Achates Power who Cummins are working with.

    Spark redundancy.

    Thanks to both posters.The MSD unit looks like it works like a diode. I have a distributorless system so maybe need 4 units.

    Spark redundancy.

    How do people do redundant spark using two feeds to one spark plug? I am thinking of using computer spark alongside magneto fixed advance as a dual system into one plug. Most auto conversion failures are ignition related.

    Glues for foam to alloy tube?

    Look at the glues used in the car industry for gluing aluminium panels. I think the primer is the critical part.

    Ragwing RW20 Stork

    I think this plane needs some horsepower to get the best out of it. Maybe an Aeromomentum or similar?

    Raptor Composite Aircraft

    Can anyone explain how the Escrow works. My understanding is that if the plane does not fly or worse the Escrow holders get there money back. So what money is really being used to build this plane?

    Hi call me Cooper, just got a J3 kitten by Hipps superbirds

    Plans are readily available on the net that can be built from . You would not in my opinion infringe on any copyright because everyone blatantly copied everyone else back then. I have copies of 3 different versions where the only difference in the wing drawings is the title block.

    Raptor Composite Aircraft

    No idea of weights but original poster seemed to think that an 0-540 would save 500lb.Would be nice to see motor and redrive on scales.

    0-540 weighs 438lb dry and Audi weighs 425.5 lbs(Audi introduces lighter, more efficient 3.0L V6 turbodiesel, can cut consumption by 20%) so only difference is redrive.

    Light weight diesel auto conversion

    Maybe Air Trikes who posts here could supply a gearbox for you. Fitting a mechanical pump and injectors is not that hard either.
