![]() Biplanes are less efficient than monoplanes, and triplanes are worse still. The stack of little horizontal Venetian blinds in the tail group is not a sensible way to achieve an effective horizontal stabilizer. The vertical tail surfaces are not large enough to keep the center of pressure where it needs to be, aft of the CM, given the long enclosed body. In this case, the person who made the drawing may be a great comic-book illustrator or computer-game designer, but he/she does not know the basics of aircraft design. Generally, the fancier the advance artwork, the less real engineering is being done. wanyanzhou has updated details to GMC(Gesture and Myoelectric control).It's just more vaporware until the hardware shows up and flies for the public.MaBe42 has updated the project titled Chaotic Lighthouse.MaBe42 has updated details to Chaotic Lighthouse.skrivanekadam11 liked My (almost) 8-bit CyberDeck.joey castillo has updated the log for Feather Op Amp Lab.MaBe42 has added a new log for Chaotic Lighthouse.Jan Říha has updated components for the project titled PionEar: Making Roads Safer for Deaf Drivers.Conor Stewart on Learning 3D Printing Best Practices From A Pro.poiuyt on This Week In Security: Gitlab, KeyPassMini, And Horse.Andrew on Learning 3D Printing Best Practices From A Pro.Dubious on 3D Model Subscriptions Are Coming, But Who’s Buying?.shod on Simulated ET To Phone Home From Mars This Afternoon.Supercon 2022: Nick Poole Makes A Jolly Wrencher Tube 5 Comments Posted in drone hacks Tagged drone, flight controller, helicopter Post navigation This latest craft is very similar to ’s spinning tricoper, and might be able to take advantage of the control scheme. is no stranger to giant VTOL aircraft, having built and flown in his own manned drones, powered by both internal combustion and electric motors. After a second test flight session to tune the flight controller settings, control authority improved, although it is still very docile in terms of response. To compensate for lag when switching between channels, had to tune the offset of the commutator disc otherwise it would veer off in the wrong direction. This means each of the servos switches between six different PWM channels throughout its rotation. Each control servo’s PWM signal routes through a commutator disc with six sectors, one for each motor of the virtual hexacopter. Instead of trying to write a custom control scheme, he configured the old KK2.15HC flight controller for a hexacopter. ![]() control setup is very creative but somewhat imprecise. Each blade is equipped with a servo-driven control surface, which can give roll and pitch control by adjusting deflection based on the blade’s radial position. The flight controller, with its own battery, is prevented from spinning with the blades by counteracting the spin of a small DC motor. The blades are simple welded aluminum frames covered with heat-shrunk packing tape, braced with wires for stiffness. To get around this, drives the 5m diameter propeller from the tips using electric motors with propellers. One of the challenges of large propellers is their high torque requirements. Small and fast tend to be the most practical for many applications, but if you’re thinking outside the box like, you can build a massive propeller and make it fly at just one revolution per second. You can either move a large volume of air slowly or a small volume of air quickly. Picking propeller size for any aircraft, but especially VTOLs, it’s a tradeoff between size and RPM. ![]()
