    the push pull create friction, i put it new and never removed it so i know it is not bent, i will put some oil a every nylon points and we'll see

    hum guess my bad english makes things unanderstanting
    so i ask again :
    i have some  friction in pitch control, is it bad?

    engineer turbo will confirm
    but i guess you gain  lift because more suface, and lift because  more reynolds number due to new wing span;
    fast calcul for complete extension :
    wing area is approx 4/3 more so you will gain minimum 1,33 more lift.But it is not completely true because washout reduces lift but on other side with more  stability at the edge of stall
    i guess you to not going longer than standard stol wing because it will change the max momentum at the wing strut liaison, and spar may not support new flexion at Gs avid is certified for. And the tail will not assume whole control if wing area is to big.

    it is usually ( for stol span) 2x18 or 3x12 per wing, perso i made 1X18 and recover lift by airfoil, so kept short flaps ( a bit extended)

    control linkage friction
    hi,
    yesterday i made some rigging, i find control colon for stab is not moving freely, there's some friction on the long command going in tail. i've read on manual commands must be tied and not loose, but in this case i really wonder if the air will act on stab to feel micro variations. i'd like input from experienced pls; do i have to trim somewhat or just put some oil ? do i need to have a very light mouvement on control colon? thx

    thx turbo, we already have talk here about trim:
    the diff between real tab and stick force mitigation is in case of broken linkage , with tab you can keep control on flying.

    all that stuff to cool inside drove me crazy. i made choice to save lot of work and weight by going on belly, then i can keep free of holes the cowling ; more aero benefits i think, specially with C cowling even if belly add some drag

    yes i got it pre welded and mounted, that's good news turbo you can start engine "easy" inside plane, was wondering how much strength i need to fire it up;
    for the trim, i updated my topic where u can have look

    it takes time .. but .. finally trim is done :  with car glass switch, it works perfectly. i used rc plane connections and wire so i can easily disconnect trim from elevator and stab from fuselage.
    the switch is on panel near the throttle command, so i can activate it with only a finger without pull hand from command. same for radio red button. allowing   to use them with no matter if pilot is left or right side

    hi  turbo i see you have pull start, do you have the pull inside cockpit? how does it feel ? i'm building with pull start choice

    the butt rib is the top stol airfoil cause it has to match the fuselage and false ribs of canopy, so the owner can switch wings with no gap
    you can see on files here how wings are made , stol,heavy hauler, speed, aerobatic

    hi
    thx turbo for your input, to extend spars, i had the big luck to find a metric sized tube that goes perfectly in speeding spar, i had to insert them by gently hit.
    as for wing span, i decided to go on a half extension to keep original short flaps and reduce big adverse yaw given by long wings and gain yaw stability with less inertia for the small avid tail
