Seven UP - rc pylon racer

thingiverse

I have already uploaded the correct version of wings (left and right), there was no hole to pass the CF tube. Thanks to Pallete for letting me know. I add servo cover for TGY-9018MG 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 recommend to print with ABS or PLA/Nylon with Carbon Fiber, little more flexible and stronger. Also you need: 1 CF tube 6mm x 780mm 1 CF rod 3mm x 780mm 2 steel rods 1.5 or 2mm x 100mm (aileron) 1 steel rod 1 or 1.2mm x 600mm (elevator) 1 M4 nut 1 M4 20mm screw to fix the wings 2 M3 nuts 2 M3 6-8mm screws to fix de cowl 2 wing servos (preferably 10mm maximum thickness) 1 elevator mini servo 1 brushless motor up to 28mm 1 brushless Esc (Amp. depends on the motor power) 1 battery 1600-2200mah 3S or more Option landing gear: 1 mini servo to drive (only insert into the socket and fix with 2 screws) 2 nuts M3 an 2 screws M3 to fix rear 3 wheels 25-35mm (nose wheel max. width 10mm) 3 M2 screws and 3 M2 nuts to fix wheels MY CONFIGURATION: Brushless XPower XB2825/6 RACER SPECIAL 3400KV ESC ZTW Mantis 65A with BEC Battery Turnigy Graphene Panther 2200mAh 3S 75C Servo Corona DS-843MG for wings and Servo EMAX ES08MD for elevator Propeller APC Electric 4.75 x 5.5 Landing gear: 1 servo Turnigy TGY-9018MG 3 wheels 25mm x 9.75mm
