Free plans for Seven UP



  • Rewiev:

    During the lockdown I had time to design a pylon racer based on a model called Petit Chelem. I have redesigned the plane to be 3D printed and wanted to use a very thin wing profile to increase speed.

    I bring you a pylon racer optimized for LW PLA. It is very light and quite strong, very easy to print on a 3D printer of a minimum of 300x300x300mm (Sidewinder X1, CR-10, ...). Two versions of tail, fixed or removable.

    Two versions of fuselage, with or without landing gears (only change part 1 of fuselage).

    SPECIFICATIONS:

    • Wingspan: 1014mm
    • Length: 782mm
    • Est. weight: 600g (without battery)
    • CG: 63mm
    • Airfoil: MH-33


    Fuselage and wings are optimized for print with LW PLA
    Cowl is recommended to print with ABS, better withstands heat
    Servo covers could be made with ABS or PLA, not recommended with LW PLA (very soft)
    Version with landing gear I recomment to print with ABS or PLA/Nylon with Carbon Fiber, little more flexible and stronger.
