    An entertaining account and well written.
    Your comments about the mud remind me that Spats are not just for show. They also allow my T600 to carry my own supply of mud!

    We now have a (relatively) shiny newish windsock and some of the hedge has been cut back, improving visibility of the sock and reducing rotor at the south end of the strip.

    Yes. And No.
    Yes, it is certainly possible to assemble a battery and motor to fit into the proposed 600kg microlight.
    If you want the power of a 912, you can have it. What you won't get is the...

    Ok, here goes:
    If we assume 6 electric microlights will be flown once per week and each uses 30kwh per flight, we have an energy requirement of 180kwh per week or 26kwh per day, or just over 1kw....

    E power is hardly in its infancy. At the turn of the last century (c1900) electric cars were dominant, pre-dating and out-selling IC engined cars, holding speed records and in use as taxis.

    Electric power has much to recommend it over IC, but it is not a direct replacement in all applications. Where power and endurance are required within a strict weight limit, electric power will never...

    If I understand correctly, to maintain an LAPL you would need to keep up hours on non-microlight aircraft. If your plan is to fly microlights, then maintaining hours on non-microlight aircraft in...

    Parasistic drag increases with the square of airspeed.
    Induced drag also increases with the square of airspeed, but so does the lift it generates. Thus as the aircraft is...
