Lavochkin La-11 RC Plane

**ATTENTION:** Original wing design has a critical flaw that needs to be addressed. A new correct wing design is available for download. The strong recommendation is to print the new wing, as all provided instructions below are based on the outdated (original) design. https://www.thingiverse.com/thing:4490163 ***Lavochkin La-11*** Wingspan: 760mm Takeoff weight: Approximately 720g Battery: 3S 800 - 1800mAh Motor: 2830-1100kv Propeller: 10x6 Flight time: Over 10 minutes (1800mAh), 8 minutes (1000mAh) COG: 70mm from the front of the wing part, exactly on the main longeron Content: /fuselage - Fuselage parts /wing - Wing parts /controls - Control surfaces /motor - Motor frame /source - Project for FreeCAD Recommended printer settings: Layer height: 0.25mm Nozzle: 0.4 - 0.5mm Filament: PETG / PLA Assembly recommendations: 1. Place the receiver in the battery tray. 2. Attach the wing to the fuselage; removal is not necessary for the entire lifespan. 3. The elevator lift should be between 8-12mm by the tail edge, no more than that. 4. If you experience difficulties with aft COG positioning, consider installing a spinner. 5. Drill a hole in the motor frame for the upper screw. 6. You may want to add tape on the cover lock for better locking. Flight recommendations: 1. Maintain airspeed; low speed equals spin stall, which is fatal. 2. Avoid sharp maneuvers using the elevator; fly smoothly. Other: You can upscale and print this model. Upscaled versions perform much better. The photo shows original 760mm and upscaled 920mm versions. The 920mm version uses a 3536-1200kv motor and a 9x6 APC-style prop. On the upscaled version, you can execute sharp maneuvers. Normal takeoff weight for the 920mm version is approximately 1050g. PS: This is my first design. I began designing a new one in another CAD with a 1.4m wingspan; hence, no updates will come for this model unless you want to do it yourself and notify me. **Update: January 20, 2020** * New fuselage_02.stl * New FreeCAD project with the corrected fuselage_02 **Update January 23, 2020** * Printed parts weight added (PLA / 0.5) * Assembly manual coming soon... **Update January 27, 2020** * Assembly manual added **Update June 21, 2020** * Spin-stall wing introduced - https://www.thingiverse.com/thing:4490163 Flight video.
