    Im sorry to hear that guido.
    The 450g you had to add probably gave the plane the extra push to be too heavy.
    I’ll have some free time soon and Im gonna try to Improve as much as possible. I unfortunatly cant fix an already printed plane completely, but i’ll try to make you happy again.
    Let me know if theres something I can do for you.

    Hello Ivan,
    all parts should still be printable, but you might have to rearrange some of them.
    Depending on the orientation of the 190mm axis, F4/F5 and the F6ABCD package could be critical.
    Let me know if you have trouble rearranging them, I can send you different gcodes.

    Hi Guido,
    I used black carbon rods, but cant see them at all. What kind if filament did you use, I used white Pla. Or maybe your filament is just less pigmented.

    Hello Brian,
    if you have trouble fitting the pins, you can try to use a 4,2mm drill and manually redrill the holes.
    I tested all holes and had a perfect fit using tubing from https://www.r-g.de/en/home.html .

    Hi Guido,
    the servos are located in the tail/rudder, so you only have extension chords going through the fuselage.
    You should glue the outer parts aswell. To avoid glue dripping outside, I allways wipe the seam with a cloth before applying activator.

    Sorry for the delay.
    I prepared some visuals to show the necessity of the Glider conversion kit or similar accessories to extend the shaft.
    I hope this helps

    Hi Guido,
    The glider conversion kit is basically an extended motorshaft. It is needed because there is not enough room for the motor.
    The motor is mounted further back in the nose. I can send you a picture when I get home.

    Hi Guido,
    nice to hear about your plans. Unfortunately there is no Build-video for the Kobuz and there probably never will be one.
    I would suggest you to build atleast one original Labprint plane before moving on the the LabGang section, because unlike the Labprint staff I am not a professional designer and therefore cant provide the same fail-proof quality. If you´re very confident in your abilitys as a builder and pilot, you can probalby do with a few tipps from the forum, but to print a little spitfire would help alot.
    Regarding the motor there is no problem with using a different one in terms of power, but it should be compatible with the Glider conversion kit (which is still necessary), should be similar in size and it should not have bad thermal properties.
    Let me know if there are still any questions.

    Greetings, Markus

    If you want, you can print them with 3 top layers. But in the testing I did the wing never broke at a glued spot, because of the pins connecting the pieces.

    Oh, my bad. But I know what you mean I’ll try to include it in the wing rework.
    This the first plane I ever build and I really appreciate the knowledge you’re giving me. If you know anything else please keep it coming.

    Hi Thomas,
    I was thinking to add some washers just for scale purposes, since the original often uses them.
    If you want to design more efficient washers, I’ll gladly add them to the files, if you want.

    Hi Randy,
    while testing, this version of the wing had the best toughness. I wanted to make sure the wing holds up even when you make faster turns or have catch the plane after a stall. I am planning to release a lighter wing and a wing with an aerobatic airfoil in the future.
    It is not easy to create a stable wing with the 3dLabprint method thats bigger than 2,5meters, thats probably why there are no larger planes.
    I cant give an est on the lighter wing tho, because I dont want to release something thats not fully stable.

    Greetings, Markus

    Hi,
    you´re right, I also noticed this Error and updated the Userguide.
    Thanks for pointing that out and let me know if you find anything else.

    Hi Thomas,
    The black parts are the upper nose cone parts and F1B.
