    And the winner is: Avirex (the French Rotax representative): $883 for the  starter only! (Loravia, another French supplier, quotes $300)

    By the way, is it possible to replace the brushes without removing the whole starter - just its back cover?

    Ok  thanks this seems to be a very good idea - i had a look at all the cables and wires to be dissasembled to take the engine out and was quite discouraged!

    582 starter trouble
    Hello all
    Some time ago, (just before the COVID mandatory containment stopped all flying activity in France) I tried to take off for a local flight, but could not start the engine. The battery was fully charged, and I even tried with an external car battery without success. I could hear the solenoid clicking, but the starter did not rotate the engine.
    What are the possible or most probable causes? (I have in mind the brushes or the solenoid contacts)
    I would if possible avoid to take out the starter, because on the MkIV this is not a simple task: I think it is not possible without removing the engine.

    Be aware that the fuel totalizer gives you the total remaining fuel. in a 2 tank setup, the motor can run out of gas with a tank empty, and fuel remaining in the other. I learned that lesson the hard way!

  8. Jeromef added a post in a topic Brake - dual calipers?   

    Hello Fred, I don't agree with that statement. In fact the pressure in the hydraulic circuit equals the force applied on the master cylinder divided by the area of the piston.
    The force applied by the caliper is the pressure multiplied by the area of the piston. If you put 2 pistons you double the force.

    Nice castle in France
    The "Chateau de Neuville", XVIth-XVIIth century, some 50km from Paris, as seen from my Avid on a bright February day.
    It is for rent for weddings or events, if you like it!

    This machine seems interesting: its a Speedwing shortwing with leading edge slats (to comply with the French ultralight requirement of a stall speed below 65km/h)
    Seems to be a C model with Mk IV cowling. (on the right in the picture)

    Hello
    Where does the name "fiber optic airstrip" come from?

    MATCO caliper P/N for MK IV?
    One of my calipers is leaking, I disassembled it and the leak is caused by corrosion in the O-ring contact area.
    This model of caliper seems to be obsolete, could someone point me to the replacement P/N?

    Just after WWI, Udet was very active in  soaring (which was at this time the only flight activity permitted to Germans).
    This could explain its exceptional ability in deadstick flight!

  19. Jeromef added a post in a topic MK IV Aerobat speedwing spar gouge/repair   

    Sure not: as the repair tube is inside the original spar, its section inertia will be lower.
    Moreover, the rivet holes will further weaken this area.

    Are the notches really useful?
    As a handle, you could use a golf ball drilled and bonded to the lever, the touch  is unmistakable!

  21. Jeromef added a post in a topic MK IV Aerobat speedwing spar gouge/repair   

    If you confirm hat the dent is less than 10% of the wall thickness, I   doubt the repair solution (from the Catalina spar extension) will be any stronger than the spar in its current state.

  22. Jeromef added a post in a topic MK IV Aerobat speedwing spar gouge/repair   

    As a structural engineer, I would say that the scratch is not in a high stress area of the spar (as it is essentally bears vertical flexion loads, the stresses are mostly at the top and bottom.)
    Personally, I would make a repair as you suggest. But its your butt in the seat, not mine!

    Are you using the flaps regularly? I tested them once, but was not convinced: they cause a lot of forward pitch. As my strip is quite long (350m) I dont really need them.
