Charliet RC Plane for Sports & Aerobatic Flying - 3D Printed

Charliet is a fully 3D-printed RC-plane for sports and aerobatic flying. It´s easy to print in regular PLA or PETG on standard sized printers. Assembly is straight forward, a comprehensive manual is provided. The design has undergone multiple iterations, balancing robustness for every-day use at a relatively low weight. The overall design elements recall classic sports RC-planes from the times, you had to build them yourself from balsa wood. Charliet prefers a dynamic flying style, yet being forgiving at low speeds. It easily does all classic aerobatic manouvers and is also fun zooming around the flying field fast and low. If you go to low – re-print. I am happy to provide this design for free to this great community! Tech. data: Wingspan: 1100mm Length: 950mm Flying weight 1250g Wing loading: 55g/dm^2 CG is on mainspar (65-69mm from leading edge) Controls: Aileron, Elevator, Rudder, Throttle Drivetrain: 35mm Outrunner, e.g.3542 1250kV / 3S 2200 mah Lipo (or similar) Requried printer build volume: approx. 220X220mm build plate, 220mm print height Design features: Airframe parts designed in desired wall thicknes – no fancy slicer settings required Comprehensive instruction manual for printing and building Rugged design for every-day use Easy battery access through removable canopy Wing-spar design can easily handle high-g manouvers Takeoff and landing from grass fields is possible Ailerons and elevator are printed in place with optimized and tested living hinges for ease of assembly Minimum amount of sourced components needed Material needed: 800g Filament (PLA / PLA Plus / PET can be used) 30g TPU 95a if you want to print the tires and hinges for the Rudder, if you don´t want to print TPU, you can source these components from your hobby shop. 1pcs. Bowden pushrod, 1000mm length, outer diam of tube approx 3mm 8pcs. Clevis for control suface linkages CA glue in thin and medium viscosity Carbon fiber pultruded stock material, 1000mm lenght (in US you can source this from Aloft Hobbies, in Europe it´s easily available e.g. at hoelleinshop or R&G): 2pcs.4x1mm Carbon strip 1000mm lenght 1pcs. 4mm Carbon rod 1pcs. 6mm Carbon tube, 4 or 5mm inner diameter works Drive train and RC-components 35mm brushless outrunner, recommended types are from 3536 to 3546 with 1200 to 1350 kV (weighting 115 to 145 grams). On prototypes, a 3546 1300kV motor on a 9x6 prop gave very good results (vertical climb, and a nice top-speed) 40A ESC 2200mAh 3S Lipo battery (there is room for bigger batteries, if you don´t mind the weight) 4 pcs. 12G servos, 9-12 mm thickness, metal gear is recommended. Don´t use the super cheap ones, this plane can go fast and you want precise controls. Go at least for medium quality. Recommended budget servos are PTK 7452 MG-Digi from Aliexpress. EMAX ES3352 Digi work very well, or you invest in KST DS113MG or similar, Receiver Servo extentions 2pcs 200mm, 2pcs. 100Mm Prop and Prop-adapter ( Small Parts: 2x M3x15 to M3x20 screw, nut and washers for mounting the landing gear, similar UNC N4-40 works as well M5 nylon bolt for screwing the wing
