    It's will be very difficult to build counter rotating gear box with outer dimensions only 200mm(7.9")

    PJ-II "DREAMER" has landing gear position indicator installed.

    Green lights - landing gear down and locked. When yellow lights is ON - gear is up.

    When "Check lights" button is pushed - all lights will stay ON.

    Today we did run power plant first time since aircraft was grounded for landing gear modification. Everything went well and PJ-II "Dreamer" is ready to fly again.

    Copilot are not needed for test run of power plant, but thanks. And to install wings takes about an one hour.

    PJ-II "Dreamer" need to get new Airworthiness Certificate - process will take about a one month, by end of March it's will be no snow left in Volgograd.
    Today we did install horizontal tail serfices. Outer wings panels we will install later, to save hangar space.

    Today we did "real live" test - checked operation retractable landing gear with engine running, to make sure that everything will work in real flight.
