    some news..
    i ve checked the empty weigh today : it comes at 200 kg / 440 lb with 5 liters of gaz.. not bad
    about roll connections, i read in book the connections must be tied strong because flutter, but i feel they are not enough soft, btw i did not checked yet in relative wind.
    what do you think they are on your plane?

    how to stop for few days
    with the inversed cylinders, you got some oil on plugs until few days, i guess for a long stop more than a week, i shut off valve
    and let engine burn all gas in lines and carb. good or bad idea?

    582 Component Tests
    as you could read in my avid topic, i lost the rpm 5 min after start
    the instrument still on but shows 0 rpm
    the line is not cut and i got 6 ohm resistor between the grey line from engine and ground: is it good number ?
    then i checked ligntnig coils : one 255 ohm, other 285; not very similar

    this is the wood speedwing prop, so i admit it turns lower rpm static but with the rpm issue appeared 5 min after start, i wonder if the numbers were good, i'll wait till the tiny tach to verify this.

         hi all!!!!
    those times give some time to work on the  avid
    today i started the engine, this means plane is finished. 
    i put 5 liter of mixed gas in tank, checked all , pressed 3 times the bubble, engaged contacts, choke, and pulled the rope; on the first try the engine wanted to live; i turned off the choke, and he started at the third pull. running smoothly. idle is great at 1800rpm,,i can go much lower but not very confortable. i got more of 5000 at full power static(iis it enough?) i run a wood  propeller.
    the temps are right in the green, water temp 140/150 F, egt between 800 and 1050 F, i saw the top egt at 4300 rpm, i guess this is the rpm to avoid inflight.
    then i lost rpm indicator, as i run the digital avid gauges, i don't kown for now if this comes from engine or instrument; btw, i think to put a tiny tach 
    then i saw liquid coolant spaying on the firewall.. after a quick search i found a micro hole in the alloy bottle. 
    Even with those little issues, i feel very happy of this first start.
    i was  afraid of the pull start, but it's ending to be very easy, and i'm happy to have keep the plane very simple; i didn't do the weigh balance yet;
    next operation: move the plane to the airfield, a very quite place with a big and long grass runway

    hello, finally the major work is done, only have to do wiring , fuel line and rigging.
    yesterday i deployed the plane, it was like a big present in the garden.
    i realy feel happy to have a new plane so vintage, from the 80's the avid now a kind of collector, now the pics :
    my best hunting :

    Chritmas present in the garden :

    the pitot made after all, not so difficult to put tube in the covered wing

    this solo 580 number is relative to performance numbers showed under, so customer can have an idea how can perform the plane if he fies solo or dual

    in this area it is more compression than flexion i guess, so the fiber tank helps a lot for this. if it was mine, i would go for repair and special care between each flight

    so to resume : -3 ° is up flap, everyone got is own rigging in range of -3/+3
     i will go for about a gently 0° first ;°)

    rigging flaps
    manual says  -3 ° for better crus speed ...so it is up or down? personally i would go for 3° down, so when you push for speed, the AoA decrease and flap finally is 0° in relative wind so less draggy.....or... -3 is up cause the flap airfoil chord is not the bottom flat line, so flap is 0° when bottom is -3
    i'm lost and don't feel very confortable with the idea of flying with up reflexing flaps
